ESDIS Weekly Metrics: March 23, 2026

Note: The volume distributed to end users per day, as a running average over the past four weeks, is 12.28 times the volume added to the archive per day.

Note: Higher product latencies for OMPS-SNPP on March 17, 2026, were due to a problem with the file system.

Note:

1. 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.  
2. 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).
3. 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, TROPOMI-SENTINEL-5P, and VIIRS-SNPP-Land, which had rates of 94%, 94%, and 78%, respectively, of NRT data requests being satisfied within 3 hours
