Notes:

Latency for a data granule is defined as the time taken from the midpoint between the start and end of acquisition of the data to the granule being ready on-line for users to download.
Duration covered by the data for a granule is defined differently for four different instruments (e.g., MODIS granules are 5 minutes long, while OMI NRT granules are 13 to 136 minutes long).
Over the past four weeks, more than 95% of near-real time (NRT) data requests for nearly all instruments were satisfied within 3 hours. The exceptions were MODIS-Aqua, OMPS-NOAA-21, TROPOMI-SENTINEL-5P, VIIRS-NOAA-20-Land, and VIIRS-SNPP-Land, which had rates of 94%, 51%, 94%, 92%, 90%, and 78%, respectively, of NRT data requests being satisfied within 3 hours.
