ESDIS Weekly Metrics: October 12, 2026

Note: The volume distributed to end users per day, as a running average over the past four weeks, is 9.294 times the volume added to the archive per day.

Note that higher product latencies for VIIRS-NOAA-20-Atmosphere and VIIRS-SNPP-Atmosphere on October 8, 2026, were due to an upstream delay.

Note that higher product latencies for OMPS-SNPP on October 8, 2026, were due to due to an upstream delay.

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, TROPOMI-SENTINEL-5P, VIIRS-SNPP-Land, and VIIRS-SNPP-Atmosphere, which had rates of 64%, 89%, 76%, and 93%, respectively, of NRT data requests being satisfied within 3 hours.
