    YTD Highlights

    5 / 1 / 2018
    • Miguel Román (GSFC/619) participated in the 2018 GEONETCast Americas (GNC-A) workshop in Mexico City. The workshop, conducted in Spanish (with English translators) was organized in collaboration with NOAA’s Satellite Products and Services Division, NASA’s Disasters Program, UNAM’s Institute of Geography, AEM (Mexican Space Agency), CENAPRED (Mexico’s Disaster Management Agency), and INEGI (Mexico’s Statistical Institute). As part of the GNC-A workshop, Román and NOAA colleagues facilitated a disaster tabletop exercise focusing on regional needs. The goals of the exercise were: (1) to provide participants with the opportunity to experience the unique roles of different stakeholder groups, (2) to discover interdependencies, (3) test collaborations, and (4) validate assumptions. Multiple scenario situations (e.g., hurricane impacts, flooding, and power outages) were seated in a regional context to reveal how satellite data and knowledge of earth and social systems could be effectively used. Over 100 local and international participants were able to assess the capabilities and needs of policy leads, regional, and on-the-ground decision makers, public media outlets, and learn what information products from the International Disasters Charter could be produced, and when and how they were available.
    • NASA’s Black Marble product suite (GSFC/619) was featured in the Bloomberg Businessweek article titled “All the Things Satellites Can Now See From Space” published on July 26, 2018. The article aimed to highlight some of the recent remote sensing applications by companies, government agencies, and NGO’s enabled by a new generation of satellites. The specific piece, written by Andre Tarar, featured a NASA study on measuring the effects of Hurricane Maria in Puerto Rico using the Black Marble product. The article (available in print and online: https://t.co/InPt3Fv6rK) accentuated the significance of the effort by the GSFC team to understand and measure the accuracy of Suomi NPP imagery through in situ measurements in producing the Black Marble product to capture the nighttime image more accurately. With improvements such as filtering out the nonelectric light, the result produced a powerful set of before-and-after images that revealed the devastating extent of power outages and other infrastructure damages post-hurricane Maria.
    • NASA’s Black Marble (GSFC/619) was featured in the released draft Recovery plan titled “Transformation and Innovation in the Wake of Devastation: An Economic and Disaster Recovery Plan for Puerto Rico” produced by the Puerto Rico government. This recovery plan was developed in response to the “Further Additional Supplemental Appropriation for Disaster Relief Requirements Act, 2018” (Public Law No. 115-123) after the catastrophic damages by Hurricane Irma and Maria in 2017; and the devastating effects on people’s health, safety, and critical infrastructure. The document considered the loss of power and destruction to the electricity grid the most damaging consequences for critical infrastructure resulting in the failure of the entire network and communication systems. Through the Black Marble, areas with significant and prolonged power disturbance were identified and the emergency response as well as short- and long-term recovery plans were staged to restore the power.
    • On 27 June 2018, Miguel Román (GSFC/619) was an invited speaker at the 2018 World-Wide Human Geography Data (WWHGD) Working Group Symposium on Human Geography Dimensions of Energy Access and Use.

    • Miguel Román (619) attended to the 2nd Ambassador Dialogue on Disaster Risk Reduction Across the Americas. The meeting was hosted by the Ambassador of Colombia, Camilo Reyes, in partnership with NASA’s Disasters Program. The dialogue focused on regional opportunities for harnessing earth science to reduce economic impacts.
    • Miguel Román (619) attended the 2018 Understanding Risk (UR) Forum in Mexico City. UR is a global community of experts and practitioners with interest in the field of disaster risk identification, specifically risk assessment and risk communication. Román participated in multiple sessions and gave two Hyperwall talks that highlighted the NASA Black Marble Science Team work during the 2017 Hurricane Season.
    • A contributing article between BBC Arabia and NASA’s Black Marble science team (619), entitled “Syria from Space”, was recently nominated for the prestigious One World Media award under their ‘Best Media’ category - https://www.oneworldmedia.org.uk/awards/longlist/ . Established in 1988, the One World Media awards recognize the best media coverage of the developing world, reflecting the social, political and cultural life of people around the globe. The awards, to be announced at the British Academy of Film and Television Arts (BAFTA) later in June, highlight the unique role of journalists and filmmakers in bridging the divide between cultures worldwide and raising awareness of underreported issues and stories.

    • The MALIBU project (Multi AngLe Imaging Bidirectional Reflectance Distribution Function small UAS) (PI: M. Román, 619; Instrument-PI: N. Pahlevan, 619/SSAI; Co-Is: Z. Wang, 619/UMD, J. McCorkel, 618, G. Bland, 610W) completed the first series of test flights at Pawnee National Grasslands, Colorado (June 28-30, 2016; link to video brief: https://youtu.be/Vd8c-4rXQOo). MALIBU is a pathfinder series of missions to develop a multi-angle reflectance measurement technique for global land product calibration and validation using small Unmanned Aircraft Systems (sUAS). The instrument package includes two multispectral imagers oriented at two different viewing angles to capture vegetation structure and spectral characteristics. The series of test flights were collocated with NIST-traceable measurements of calibration tarps, and supported by a ground surveying crew for post-process geolocation. The last test flight, Flight #003 on 30 June 2016, was successfully completed during a Landsat-8 overpass. These measurements will assist in evaluating OLI-derived surface reflectance and biogeophysical products at unprecedented scales (i.e., high spatial (<20 cm) and multi-angular (< 0.5 degree) resolutions). The MALIBU team would like to thank Christy Hansen (610), Barbara Justis (840), and Gerrit Everson (830) for their assistance during the MALIBU Airworthiness and Flight Safety Review Board (AFSRB), and for their guidance in processing the FAA Certificates of Authorization (COA-G) for the Pawnee field site. This work was funded under the NASA/GSFC IRAD and SBIR programs.

    Brief Bio

    SummaryMiguel O. Román (WaPo Profile; Google Scholar Profile) is a Research Physical Scientist in the Terrestrial Information Systems Laboratory  at NASA's Goddard Space Flight Center. A major focus of Román's work is the development and applied use of nighttime visible imagery from polar-orbiting satellites. He pioneered and oversees production of NASA's Black Marble, a product suite that enables monitoring of power failures during major disasters and the assessment of underserved and vulnerable communities worldwide.

    At the agency level, Román serves as NASA's Terra, Aqua, and Suomi NPP's Land discipline lead, helping manage a team of 22 competitively-selected investigators in charge of generating long-term data records from the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Visible Infrared Imaging Radiometer Suite (VIIRS). He has been principal investigator on over $5 million of external funding for the development and use of operational products from MODIS and VIIRS. As a Disaster Coordinator with NASA's Disasters Program, Román has strengthened engagement with stakeholders from across industry, academia, civil society groups, and NGOs to improve decision-making in disaster scenarios and risk reduction strategies.

    At the international level, Román is currently assigned as an agency representative to the Committee on Earth Observation Satellites (CEOS) and the Group on Earth Observations (GEO). His contributions to inter-agency and inter-governmental initiatives, and the wealth of satellite measurements available from his work, are providing stakeholders with the fundamental data sets and strengthened capacity required to better understand and mitigate disaster risks, promote sustainable and resilient urban infrastructure, while addressing the immediate energy needs of historically-disadvantaged communities.

    Román is the recipient of the Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor bestowed by the United States government on scientists and engineers beginning their independent careers.
