  1. Exploring Land Processes and Climate Variations through Giovanni SuhungShen and James Acker Dr. Leptoukh Online Giovanni Workshop

  2. Remotely Sensed Land Products in Giovanni • Land Cover Types/Dynamics (MODIS) • Vegetation Index (MODIS) • Land Surface Temperatures (MODIS) • Soil Moisture (AMSR-E) • Snow/Ice Occurrence Frequency (NESDIS/IMS) • Active Fires (MODIS) • Surface Albedo (MODIS) • Nighttime Lights (DMSP-OLS) • http://disc.sci.gsfc.nasa.gov/mairs/data-holdings Dr. Leptoukh Online Giovanni Workshop

  3. Spatial Resolutions of Products • Low resolution: 1x1 deg (LST, VI, Fire, Soil Moisture, Snow/Ice), global coverage , spatially aggregated from original global higher resolution data (mostly 0.05x0.05 deg) • Medium resolution: 0.05x0.05 deg (LST, VI, Albedo), global coverage , standard products created by science team • Higher resolution: 1x1 km (LST, Fire) or 0.5x0.5 km (Land Cover Types) over Asian region only (0o-60oN, 60oE-150oE) , processed from original tiled data files and projected to cylindrical equidistance map projection Dr. Leptoukh Online Giovanni Workshop
