    • Brief Bio

    Robert Wolfe has been a key member of NASA GSFC's Terrestrial Information Systems Laboratory for 25 years starting as a contractor in the early MODIS years and then as a NASA civil servant for the last 15 years. During this time, Wolfe played many important roles in important core laboratory activities such as the design, development, deployment and enhancement of the laboratory’s data systems, including MODAPS, LAADS and the VIIRS Land SIPS. In addition, he has been the laboratory’s main interface to the MODIS land science team and worked closely with others in the laboratory to develop essential areas such as starting the MODIS Land quality assurance team, as well as, the MODIS Land validation activities. He also led the MODIS, VIIRS and GOES geolocation teams and played key roles in development and implementation of advanced gridding techniques. Mr. Wolfe has represented the laboratory in interactions with its many partners including GSFC management, NASA HQ, ESDIS, LP and NSIDC data centers, Individual Mission Teams, NOAA and the US Forest Service. Mr. Wolfe is also the Terra Deputy Project Scientist for Data. In this role, in addition to helping the Terra Project Scientist with many other duties, he helped produce six very highly rated proposals for extending the Terra mission. He has also participated in laboratory staffing and resource decisions and representing the laboratory at meetings such as the ESIP Federation and the ESDS WGs. Plus, he has documented and publicized many of the laboratories accomplishments through many external publications as well as presentations at conferences. During Wolfe’s tenure with the laboratory he has led and collaborated with the lab’s civil servants and contractors and understands how their strengths can be leveraged to meet the laboratory commitments and to continue to make significant contributions to NASA’s Earth Science mission. In 2017, Mr. Wolfe became the Assistant Chief of the Terrestrial Information System Laboratory and in 2018 became the LAADS DAAC manager.

    Robert Wolfe has worked in the areas of satellite remote sensing and computer science for 40 years. In 2016, he completed a two-year detail at the US Global Change Research Program (USGCRP) as the technical leader of the Global Change Information System (GCIS). At USGCRP, he led the successful deployment of GCIS in support of the 2014 National Climate Assessment (NCA). He also helped deploy the NCA website and a new version of the USGCRP home page. Wolfe led the GCIS team to add more information to the GCIS system, included structured data for a set of USGCRP Climate Indicators, more detailed information supporting the NCA, and structured data for USGCRP's 2016 Climate and Health Assessment and the 2018 NCA.

    For the last 14 years Wolfe has been NASA’s Earth Observing System (EOS) Terra Satellite Deputy Project Scientist for Data and played a key role in preparing six successful senior review mission extension proposals that justified extending the unique 20-year Earth Science data record produced by Terra's five instruments.

    Wolfe has led the development of advanced algorithms to accurately Earth-locate (geolocate) NASA’s EOS Moderate Resolution Imaging Spectroradiometer (MODIS) data and to grid land science data using both proven and innovative techniques. He extended these techniques for other instruments including the Visible Infrared Imager Radiometer Suite (VIIRS) data from the on Suomi National Polar-orbiting Partnership (SNPP) and NOAA/NASDA Joint Polar Satellite System (JPSS), and the Advanced Baseline Imager (ABI) data on the NOAA/NASA Geostationary Operational Environmental Satellite (GOES) 16 and 17 satellites.

    Starting in 2005, Robert led the team selected to create and operate the Land Product Evaluation and Test Element (PEATE), then part of NASA’s Science Data Segment’s effort to evaluate the operational Land algorithms that are being used for the VIIRS on the SNPP satellite. This system has evolved into the VIIRS Land Science Investigator-led Processing System (SIPS) and is producing a long-term VIIRS Level 1 and Land product data stream for NASA.

    For more than 25 years, he has played a key role within the MODIS science support team contributing to a number of areas of including integration and testing of MODIS science algorithms and science data processing. This important and complex activity involved the integration of a large number of interdependent algorithms and coordination among many scientists and engineers spread across government and university organizations.

    In addition to his project related work, Wolfe has participated as Co-I or collaborator on a number of competitively funded research activities, including teams that: 1) developed a Landsat based map of the global urban areas; 2) developed a global forest disturbance map from Landsat data; 3) made MODIS products more accessible to the North American Carbon Project investigators by filling temporal and spatial gaps in MODIS standard products; 4) used MODIS phenology to help predict the spread of Africanized Honey Bees; 5) developed a new service for Data Quality Screening; 6) developed a new Terrestrial Surface Climate Data Record; and 7) developed a new Global Urban Map. He continues to work on proposals for new funding for additional projects and activities.

    Over his career, Wolfe published over 120 scientific, technical, and symposia papers, has a research h-index of 26, and his publications have been sited over 6100 times (based on 105 publications in Researcher ID, October 2020). Wolfe has made presentations at numerous domestic and international meetings, peer-reviewed scientific papers for many publications, and has been a key participant in many NASA science team meetings, advisory panels and review panels.

    Positions/Employment

    8/2005 - Present

    Computer Scientist

    NASA Goddard Space Flight Center, Greenbelt, MD


    Robert Wolfe joined NASA as a civil servant in 2005 after having worked in private industry for 25 years. After joining the government, he continued his primary work on the MODIS and VIIRS missions and soon assumed broader programmatic roles, such as the Terra Mission Deputy Project Scientist for Data. In 2017, Mr. Wolfe became the Assistant Chief of the Terrestrial Information System Laboratory and in 2018 became the LAADS DAAC Manager.

    In May 2016, Mr. Wolfe completed a two-year detail at the US Global Change Research Program as the technical leader of the Global Change Information System (GCIS). During his first year at USGCRP, he led the successful deployment of GCIS in support of the 2014 National Climate Assessment (NCA). He also helped deploy the NCA website and a new version of the USGCRP web site and participated in activities to support the Sustained National Climate Assessment.

    Starting in 2006 as the Terra Mission Deputy Project Scientist for Data, Mr. Wolfe played key roles in the Terra mission, particularly related to the task of Terra data production, archive and distribution. As part of his duties he has also been a key participant in the last six Terra mission extension proposals that resulted in funding to continue Terra’s very valuable science mission into the future. Wolfe has presented the Terra budget in annual budget reviews and participated in understanding and developing solutions for spacecraft and instrument anomalies. As the Terra spacecraft and instruments age, anomalies have occurred such as the spacecraft battery anomaly. Along with the Terra Project Scientist Dr. Kurt Thome, Wolfe worked with the Terra spacecraft operations and instrument science teams to understand the impact of these anomalies and to help find solutions that would maximize the scientific return from the remaining mission lifetime. He also participates in monthly status meetings with the EOS project scientist reporting on both the Terra mission and data system related issues. During this time with the Terra project scientist and others, he participated in research that used NASA remote sensing data to better understand the urban heat islands.

    In 1995, Robert Wolfe began supporting the MODIS Science Team. His duties included: development of an approach for the Level 3 mapping software for the land team scientists, coordinating and providing support for MODIS meetings and coordinating the deliveries of an integrated package of MODIS software. This was a very important and complex activity that involved integration of a large number of interdependent algorithms. In this work, he worked well across the different organizations involved: NASA headquarters, government and university science team members and their associates, and multiple NASA data centers. He played a key role in 20 years of MODIS Level 1, Land and Atmosphere science data processing, which included several full reprocessing that have created a decadal time-series of high-quality MODIS products. Starting in 2005, he led the team selected to create and operate the Land Product Evaluation and Test Element (PEATE), part of NASA’s Science Data Segment’s effort to evaluate the operational Land algorithms that are being used for the VIIRS sensor on the Suomi NPP (SNPP) satellite. This system has evolved into the VIIRS Land Science Investigator-led Processing System (SIPS) and is producing a long-term VIIRS Level 1 and Land product data stream for NASA.

    In addition to these duties, he has been involved in EOS community efforts such as chairing the EOS Science Working Group on Data (SWGD). During this time he helped organize and lead the 2002 EOS Data Access and Usability Workshop. This workshop provided valuable feedback from the Earth science and application communities that helped improving the EOS data systems. Mr. Wolfe Co-chaired the Earth Science Data Systems Reuse Working Group from 2004 to 2009. He led this group of both NASA and University Investigators to lower barriers for reusing software in the Earth Science community. In 2009 and 2010, Wolfe participated in the Data Systems Working Group for the Decadal Survey Era.

    Another of Robert Wolfe’s technical responsibilities has been to oversee MODIS, VIIRS and GOES geolocation (earth location). Work in this area includes understanding and providing feedback on the geometric performance of these instruments. MODIS land science is the primary driver for very accurate geolocation knowledge. Since the launch of MODIS on Terra in Dec. 1999, the team lead by Wolfe used a global network of ground control points to operationally reduce the location errors to the accuracy required for terrestrial global change applications. Wolfe and his team used the same techniques for MODIS on Aqua (launched in May 2002) to achieve nearly the same accuracy as MODIS on Terra. Soon after VIIRS was launched in Oct. 2012, Wolfe’s team also achieved similar accuracy and is continuing to improve the VIIRS geolocation accuracy as this new instrument’s on-orbit geometric performance is better understood. This work was extended to the VIIRS instrument launched in 2017 on the NOAA/NASA Joint Polar Satellite System (JPSS), and the first Advanced Baseline Imager (ABI) launched in 2016 on the NOAA/NASA Geostationary Operational Environmental Satellite (GOES) 16, and a second ABI launch on GEOS-17 launched in 2018.

    In addition to his project related work and beginning in 2003, Mr. Wolfe also performed the duties of either Principle Investigator (PI), Co-Investigator (Co-I) or Collaborator on several peer-review funded mission science teams and individual research efforts. These include serving as: PI on the SNPP science team from 2003 to 2013; PI on the MODIS science team from 2007 to 2010; Co-I on the Landsat Ecosystem and Disturbance Mapping Adaptive Processing System (LEDAPS) project from 2003 to 2008; Co-I on the MODIS for North American Carbon Project (MODIS 4 NACP) from 2006 to 2009; Co-I on the Improving Prediction of Africanized Honey Bee Distribution project from 2008 to 2011; Co-I on the Data Quality Screening Service project 2009 to 2011; Co-I on the Terrestrial Surface Climate Data Record project from 2009 to 2014; and Co-I on the Global Urban Mapping project from 2011 to 2014. Mr. Wolfe also continues to work on proposals for new funding for additional projects and activities.

    Over his career, Mr. Wolfe has mentored other scientists and colleagues. Recently, he mentored NASA early-career scientists Miguel Román, Ping Zhang, Bin Tan and Joanne Nightingale. With Wolfe’s help and encouragement, these young scientists are developing the personal and scientific skills needed to make significant contributions toward NASA’s long-term goals as well as their personal goals.

    Brief Bio

    Robert Wolfe has been a key member of NASA GSFC's Terrestrial Information Systems Laboratory for 25 years starting as a contractor in the early MODIS years and then as a NASA civil servant for the last 15 years. During this time, Wolfe played many important roles in important core laboratory activities such as the design, development, deployment and enhancement of the laboratory’s data systems, including MODAPS, LAADS and the VIIRS Land SIPS. In addition, he has been the laboratory’s main interface to the MODIS land science team and worked closely with others in the laboratory to develop essential areas such as starting the MODIS Land quality assurance team, as well as, the MODIS Land validation activities. He also led the MODIS, VIIRS and GOES geolocation teams and played key roles in development and implementation of advanced gridding techniques. Mr. Wolfe has represented the laboratory in interactions with its many partners including GSFC management, NASA HQ, ESDIS, LP and NSIDC data centers, Individual Mission Teams, NOAA and the US Forest Service. Mr. Wolfe is also the Terra Deputy Project Scientist for Data. In this role, in addition to helping the Terra Project Scientist with many other duties, he helped produce six very highly rated proposals for extending the Terra mission. He has also participated in laboratory staffing and resource decisions and representing the laboratory at meetings such as the ESIP Federation and the ESDS WGs. Plus, he has documented and publicized many of the laboratories accomplishments through many external publications as well as presentations at conferences. During Wolfe’s tenure with the laboratory he has led and collaborated with the lab’s civil servants and contractors and understands how their strengths can be leveraged to meet the laboratory commitments and to continue to make significant contributions to NASA’s Earth Science mission. In 2017, Mr. Wolfe became the Assistant Chief of the Terrestrial Information System Laboratory and in 2018 became the LAADS DAAC manager.

    Robert Wolfe has worked in the areas of satellite remote sensing and computer science for 40 years. In 2016, he completed a two-year detail at the US Global Change Research Program (USGCRP) as the technical leader of the Global Change Information System (GCIS). At USGCRP, he led the successful deployment of GCIS in support of the 2014 National Climate Assessment (NCA). He also helped deploy the NCA website and a new version of the USGCRP home page. Wolfe led the GCIS team to add more information to the GCIS system, included structured data for a set of USGCRP Climate Indicators, more detailed information supporting the NCA, and structured data for USGCRP's 2016 Climate and Health Assessment and the 2018 NCA.

    For the last 14 years Wolfe has been NASA’s Earth Observing System (EOS) Terra Satellite Deputy Project Scientist for Data and played a key role in preparing six successful senior review mission extension proposals that justified extending the unique 20-year Earth Science data record produced by Terra's five instruments.

    Wolfe has led the development of advanced algorithms to accurately Earth-locate (geolocate) NASA’s EOS Moderate Resolution Imaging Spectroradiometer (MODIS) data and to grid land science data using both proven and innovative techniques. He extended these techniques for other instruments including the Visible Infrared Imager Radiometer Suite (VIIRS) data from the on Suomi National Polar-orbiting Partnership (SNPP) and NOAA/NASDA Joint Polar Satellite System (JPSS), and the Advanced Baseline Imager (ABI) data on the NOAA/NASA Geostationary Operational Environmental Satellite (GOES) 16 and 17 satellites.

    Starting in 2005, Robert led the team selected to create and operate the Land Product Evaluation and Test Element (PEATE), then part of NASA’s Science Data Segment’s effort to evaluate the operational Land algorithms that are being used for the VIIRS on the SNPP satellite. This system has evolved into the VIIRS Land Science Investigator-led Processing System (SIPS) and is producing a long-term VIIRS Level 1 and Land product data stream for NASA.

    For more than 25 years, he has played a key role within the MODIS science support team contributing to a number of areas of including integration and testing of MODIS science algorithms and science data processing. This important and complex activity involved the integration of a large number of interdependent algorithms and coordination among many scientists and engineers spread across government and university organizations.

    In addition to his project related work, Wolfe has participated as Co-I or collaborator on a number of competitively funded research activities, including teams that: 1) developed a Landsat based map of the global urban areas; 2) developed a global forest disturbance map from Landsat data; 3) made MODIS products more accessible to the North American Carbon Project investigators by filling temporal and spatial gaps in MODIS standard products; 4) used MODIS phenology to help predict the spread of Africanized Honey Bees; 5) developed a new service for Data Quality Screening; 6) developed a new Terrestrial Surface Climate Data Record; and 7) developed a new Global Urban Map. He continues to work on proposals for new funding for additional projects and activities.

    Over his career, Wolfe published over 120 scientific, technical, and symposia papers, has a research h-index of 26, and his publications have been sited over 6100 times (based on 105 publications in Researcher ID, October 2020). Wolfe has made presentations at numerous domestic and international meetings, peer-reviewed scientific papers for many publications, and has been a key participant in many NASA science team meetings, advisory panels and review panels.
