ESDIS Weekly Metrics: April 13, 2026

Note: The volume distributed to end users per day, as a running average over the past four weeks, is 2.863 times the volume added to the archive per day.

Note that higher product latencies for:

OMPS-SNPP on April 5 and 9, 2026, were due to re-running the L1As for those to verify a new table.
TROPOMI-SENTINEL-5P on April 6, 2026, were due to weekend failures.

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 OMPS-NOAA-21, OMPS-SNPP, TROPOMI-SENTINEL-5P, and VIIRS-SNPP-Land, which had rates of 54%, 94%, 91%, and 79%, respectively, of NRT data requests being satisfied within 3 hours.
OMPS-NOAA-21 was just added to the cumulative LANCE latency chart.
