2. Duration covered by the data for a granule is defined differently for different instruments (e.g., MODIS granules are 5 minutes long while OMI NRT granules are 13 to 136 minutes long).
3. Over the last 4 weeks, over 95% of NRT data requests for all instruments except for 3 instruments (OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, and VIIRS-SNPP-Land) were satisfied within 3 hours. OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, and VIIRS-SNPP-Land over 89%, 83%, and 77% of the NRT data requests were satisfied within 3 hours, respectively.
