MODIS Science Team The MODIS Science Team is a coordinated group of researchers and technical specialists responsible for the scientific validation, algorithm development, and product delivery of Moderate Resolution Imaging Spectroradiometer datasets produced for the Terra (satellite), Aqua (satellite), and related remote sensing missions. The team integrates expertise from federal agencies, academic institutions, and research centers to guide retrieval algorithms, calibration protocols, and long-term Earth observation strategies. It supports applications across atmospheric science, oceanography, cryosphere studies, and terrestrial ecology through sustained interaction with operational programs and international scientific networks.

Overview

The team provides scientific oversight for the MODIS instrument series on Terra (satellite), Aqua (satellite), and interfaces with programs managed by National Aeronautics and Space Administration, National Oceanic and Atmospheric Administration, Jet Propulsion Laboratory, and Goddard Space Flight Center. It advances remote sensing methods linked to Landsat, Sentinel-3, Suomi NPP, NOAA-20, and intercalibration activities involving the Global Climate Observing System and Committee on Earth Observation Satellites. Members develop and maintain data products distributed via platforms such as NASA Earth Observing System Data and Information System and collaborate with field campaigns like ABoVE and ARCTAS.

History and Formation

The team formed after the MODIS instruments were selected for flight on Terra (satellite) (originally EOS-AM-1) and Aqua (satellite) (originally EOS-PM-1), building on heritage from projects including Landsat program and the Nimbus program. Key early meetings involved stakeholders from Jet Propulsion Laboratory, Goddard Space Flight Center, University of Colorado Boulder, California Institute of Technology, and University of Maryland, College Park. Milestones included algorithm baselines established alongside missions such as SeaWiFS, ERS-2, and contributions to intercomparison efforts with AVHRR on NOAA platforms and calibration ties to RADARSAT.

Organization and Membership

Membership spans investigators at institutions like Massachusetts Institute of Technology, University of Arizona, University of California, Santa Barbara, Oregon State University, University of Washington, Columbia University, Harvard University, Stanford University, Princeton University, University of Colorado Boulder, University of Wisconsin–Madison, Scripps Institution of Oceanography, Plymouth Marine Laboratory, and Commonwealth Scientific and Industrial Research Organisation. Federal agency participants include representatives from NASA, NOAA, United States Geological Survey, National Snow and Ice Data Center, and National Center for Atmospheric Research. The governance model uses teams organized by discipline—ocean color, land surface, atmospheric composition, cryosphere—with liaisons to program offices such as NASA Headquarters and science review panels like the National Research Council committees.

Scientific Objectives and Research Areas

Primary objectives cover quantitative retrievals of surface reflectance, aerosol optical depth, sea surface temperature, chlorophyll concentration, vegetation indices, snow and ice extent, and fire disturbance, interfacing with research domains linked to Intergovernmental Panel on Climate Change, Global Carbon Project, International Geosphere-Biosphere Programme, and World Climate Research Programme. Research areas include algorithm development for atmospheric correction informed by campaigns such as ACE-Asia and SAGE III comparisons, biogeochemical proxy calibration for studies tied to the Census of Marine Life and International Ocean Colour Coordinating Group, permafrost and cryosphere monitoring relevant to International Arctic Science Committee, and land-cover change analyses comparable to Global Land Cover Facility outputs.

Instruments, Data Products, and Methodologies

The team supports MODIS Level 0–3 products, including surface reflectance, BRDF/albedo, Leaf Area Index, fire radiative power, aerosol products, cloud mask, and ocean color products comparable to outputs from SeaWiFS and VIIRS. Methodologies include vicarious calibration using sites like Sahara Desert Calibration Site and Gunflint Lake analogs, matchup analyses with in situ programs such as AERONET, ARGO (oceanography), FLUXNET, and ship-based cruises coordinated with Joint Global Ocean Flux Study. Algorithm suites reference community standards such as those developed by Committee on Earth Observation Satellites, best-practice protocols from Global Climate Observing System, and validation frameworks promoted at meetings like the American Geophysical Union Fall Meeting.

Major Contributions and Impact

Contributions include generation of multi-decadal climate data records used in assessments by the Intergovernmental Panel on Climate Change and insights into global fire regimes utilized by United Nations Environment Programme. MODIS Science Team outputs underpin studies of terrestrial primary productivity referenced by the Global Carbon Project, coastal eutrophication work cited by United Nations Educational, Scientific and Cultural Organization programs, and cryospheric change analyses informing International Arctic Science Committee and Scientific Committee on Antarctic Research syntheses. The team’s calibration and algorithm intercomparisons have influenced sensor design decisions on Sentinel-3, VIIRS, and future missions such as PACE (mission).

Partnerships and Collaborations

The team collaborates widely with academic consortia, federal laboratories, international space agencies including European Space Agency, Japan Aerospace Exploration Agency, Canadian Space Agency, and with observation networks such as AERONET, FLUXNET, Argo, and GPM. Collaborative projects and field campaigns include ties to ABoVE, ORACLES, SAGE, ACE-Asia, and joint calibration efforts through the Committee on Earth Observation Satellites and the Group on Earth Observations. The team engages in capacity building with regional programs like Group on Earth Observations initiatives in partnership with institutions such as Indian Space Research Organisation and Brazilian National Institute for Space Research.
