ESDIS Weekly Metrics: July 28, 2025

Note:

1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 3.225 times the volume added to the archive per day.
2. The drop in archive and ingest on July 26, 2025, is due to incomplete data processed to EMS.

LANCE Data Latency

Note:

Higher product latencies for:

• VIIRS-NOAA-20-Land, on July 21, 2025, due to a missing/delayed ancillary input file.
• TROPOMI-SENTINEL-5P, on July 23, 2025, is under investigation.
• OMPS-SNPP, on July 26, 2025, due to receiving data late from EDOS.
• VIIRS-SNPP-Land, on July 26, 2025, due to L0 delivery delays.
• VIIRS-SNPP-Atmosphere, on July 26, 2025, is under investigation.

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 for that granule to the granule’s being ready online for users to download.
2. Duration covered by the data for a granule is defined differently for different instruments (e.g., MODIS granules are 5 minutes long while OMI NRT granules are 13 to 136 minutes long).
3. Over the last 4 weeks, over 95% of NRT data requests for all instruments except for 8 instruments (OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, TROPOMI-SENTINEL-5P, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-SNPP-Atmosphere, VIIRS-NOAA20-Atmosphere, and VIIRS-NOAA-21-Land) were satisfied within 3 hours. OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, TROPOMI-SENTINEL-5P, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-SNPP-Atmosphere, VIIRS-NOAA20-Atmosphere, and VIIRS-NOAA-21-Land over 83%, 86%, 91%, 90%, 65%, 85%, 87%, and 75% of the NRT data requests were satisfied within 3 hours, respectively.
4. MOPITT in Safe Mode: On February 1, 2025, the Terra Measurement of Pollution in The Troposphere (MOPITT) instrument went into safe mode. While in safe mode, there will be no MOPITT science data collected. On March 31, 2025, the MOPITT Subsetter was decommissioned.
