ESDIS Weekly Metrics: September 7, 2026

Note: The volume distributed to end users per day, as a running average over the past four weeks, is 8.726 times the volume added to the archive per day.

Notes:

In previous reports, we did not include NRT products in the cloud and on-prem. The products were from NRT providers. Products now included contain NRT in the product or provider name, project type containing "LANCE," or collection data type containing "expedited" or "near_real_time."

The following higher than normal latencies will be updated next week.

VIIRS-NOAA-20-Atmosphere from August 30 to September 5, 2026
VIIRS-SNPP-Land on September 1, 2026
VIIRS-SNPP-Atmosphere on September 2, 2026
VIIRS-NOAA-20-Land on September 4, 2026

Notes:

Higher product latencies for OMPS-SNPP on August 24, 2026, were due to a database issue.

The following higher-than-normal latencies will be updated next week:

OMPS-SNPP on August 31, 2026, and September 4, 2026
OMI-AURA on September 4, 2026
TROPOMI-SENTINEL-5P on September 4, 2026

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, VIIRS-NOAA-20-Land, and VIIRS-SNPP-Land, which had rates of 60%, 94%, 88%, 91%, and 79%, respectively, of NRT data requests being satisfied within 3 hours.
