ESDIS Weekly Metrics: March 30, 2026

Note: The volume distributed to end users per day, as a running average over the past four weeks, is 9.87 times the volume added to the archive per day.

Note: Higher product latencies for

TROPOMI-SENTINEL-5P on March 23, 2026, were due to failed granules.
VIIRS-NOAA-20-Land on March 26, 2026, were due to bad data.

Note:

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 TROPOMI-SENTINEL-5P, VIIRS-NOAA-20-Land, and VIIRS-SNPP-Land, which had rates of 89%, 94%, and 77%, respectively, of NRT data requests being satisfied within 3 hours.
