MODIS Land Science Products Production Robert E. Wolfe NASA Goddard Space Flight Center, Code Greenbelt, MD, USA This work was performed in the Terrestrial Information Systems Branch (Code 614.5) at NASA’s Goddard Space Flight Center Laboratory for Terrestrial Physics. Acknowledgement MODIS on EOS Terra and Aqua  The MODerate Resolution Imaging Spectroradiometer (MODIS), a key instrument for NASA’s Earth Observing System (EOS)  MODIS was launched on board the Terra spacecraft in Dec (first light on Feb. 24, 2000) and on board the Aqua spacecraft in May 2002 (first light on June 24, 2002)  Spatial resolution at nadir: 250m (2 bands), 500m (5 bands) and 1000m  12 bit (0-4095) dynamic range MODIS Land Products Energy Balance Product Suite  Surface Reflectance  Land Surface Temperature and Emmisivity  Bi-directional Reflectance Distribution Function (BRDF) and Albedo  Snow cover and sea-ice extent Vegetation Parameters Suite  Vegetation Indices  Leaf area index and Fraction (LAI) and Fraction of Photosynthetically Active Radiation (FPAR)  Gross and Net Primary Production (GPP/NPP) Land Cover/Land Use Suite  Land Cover/Vegetation Dynamics  Vegetation Continuous Fields  Vegetation Cover Change  Fire/Thermal Anomalies and Burned Area Getting MODIS Land Data 2 2 Land Science Team – Phase 2  Overall – Phase 1 Land Team intact and strengthened  Separate funding for Validation Coordination and Rapid Response  Larger Science Team (27 total)  Algorithm Maintenance and Validation Team (10)  EOS Science – Data Users (17)  Four new/improved Land products: Plant Water Content, Evaporation, Improved Surface Reflectance, Physical Based Continuous Fields and Land Cover  Land Discipline Leader: Dr. Chris Justice, UMD 4 4 MODIS Collections Each collection represents an improvement in science quality 7 7 MODIS Product Format  Hierarchical Data Format (HDF) – self describing file format  Science Data Sets (SDSs) – 2D, 3D or 4D arrays  Bit Fields – unsigned integers broken into groups of bits  Discrete values – e.g., Snow, Cloud, etc.  Scaled Integers – valid range, scale and offset included  Attributes – text or other data annotating the file (global) or arrays (SDSs)  Metadata – ECS product metadata (stored as attributes)  includes QA information, date/time products acquired/produced, etc. .met file contains the ECS core metadata: some fields (QA, etc.) may be updated when product distributed  HDF-EOS Metadata (SWATH or GRID) – geometric information that relates data to specific earth locations 8 8 Retrieved geophysical parameters at same location and in same format as MODIS Level 1 instrument data  288 granules/day;
