  • Brief Bio

    Dr. Kevin Turpie received a Bachelor of Science in Computer Science at the University of Maryland in 1986, a Master of Science in Applied Mathematics at The Johns Hopkins University in 1991, and a PhD in Geographic Sciences at the University of Maryland 2012. He currently teaches graduate and undergraduate environmental remote sensing UMBC.

    He has worked at Goddard Space Flight Center on ocean color problems since 1993, leading focused groups of scientists, analysts, and computer specialists on projects related to the CZCS, MODIS, SeaWiFS, and VIIRS instruments, including the development a MODIS science computer facility, global ocean production models, and web-based data analysis and visualization tools to assess data quality and trends. In 2004, Dr. Turpie was appointed the Ocean Color Deputy PI on the S-NPP NASA Science Team, leading a team to evaluate VIIRS sensor characteristics, calibration, and ocean color data product algorithms. In 2010, he became the Ocean Color Science PI, leading the evaluation of VIIR flight data and was elected by the science team to be the Ocean Discipline Lead, coordinating PI efforts, presentations and reports, and liaising between the team and program and project management. In this role, Dr. Turpie represented the interests of NASA and the Ocean Color research community in interactions with NASA and NOAA engineering teams, the NOAA ocean color calibration and validation team, the NRC Committee on Assessing Requirements for Sustained Ocean Color Research and Operations, and commercial organizations handling operational sensor calibration and data product processing. Dr. Turpie also holds leadership roles in a number of cross-discipline organizations related to hyperspectral remote sensing and model of coastal and inland waters and wetlands. He has published two peer review journal papers this year in this area.

    Dr. Turpie is also a member of the Hyperspectral Infrared Imager (HyspIRI) Science Study Group, where he is applying his combined experience of terrestrial and aquatic problems to help define the future HyspIRI mission. He has expanded this role by becoming the founding chair of the HyspIRI Aquatic Studies Group (HASG), which is a growing organization of about five dozen international scientist and researchers focused on development of hyperspectral algorithms and data products for coastal and inland water applications.

    Research Interests

    Remote Sensing of Aquatic Environments from Space

    Dr. Turpie's current research can be divided into two major areas: ocean color and coastal remote sensing. For the former, he interesting in studying passive sensor calibration and behavior, and how these influence remote sensing applications in marine and aquatic remotes sensors in the 0.35-2.5 micron range. He is also interested in development of remote sensing models that model the transmission and reflection of light at the air-water interface and how this changes with deep or the presents of emergent vegetation. With regard to the latter major area, Dr. Turpie is exploring ways to retrieve information about the conditions in shallow water environment, including coastal marsh ecosystems, through remote sensing. In particular, he is interested in developing methods to assess and record changes in the canopy architectural of coastal marshlands that are caused by climate change and human activities. His research looks to accomplish this through applications of satellite data, ground data, and radiative transfer modeling. It is his hope that the result will contribute a methodology to understand, monitor and manage these precious ecological resources.

    Current Projects

    Joint Polar Satellite System (JPSS) Visible Infrared Imaging Radiometer Suite (VIIRS)

    Dr. Turpie is providing expertise toward instrument calibration and characterization through assessing the impact of instrument performance on ocean color science data quality.

    National Polar-orbiting Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS)

    Dr. Turpie is involved in applying prelaunch characterization data and investrating on-orbit calibration of the VIIRS instrument and its affect on the science quality of ocean color data products.

    Hyperspectral Infrared Imager (HyspIRI)

    HyspIRI is a Decadal Survey mission designed to observe ecosystems.  Dr. Turpie is providing his input regarding remote sensing of aquatic ecosytems of coastal and inland waters.

    Teaching Experience

    Dr. Turpie is a research associate professor at UMBC.  He is affiliated with the Dept. of Geography and Environmental Systems.  He teaches a course in remote sensing of the environment.  This is cross-listed as both an undergraduate and graduate course.

    Dr. Turpie's teaching interests include graduate and undergraduate courses or seminars introducing remote sensing techniques using satellite and airborne imagery in conjunction with in situ data and models, particularly focused on marine and aquatic environments and their response to climate change, human influence; wetland field work design and data collection techniques for support of remote sensing; and remote sensing sensor calibration and validation for aquatic research; and quantitative geography, especially for coastal regions.
