LANCE Data Latency

ESDIS_2026_01_12_2

Note:

Higher product latencies for:

  • OMPS-SNPP, on December 30, 2025, was due to a problem with the Nadir L1A lookup table that delayed processing.
  • OMI-AURA , on January 2, 2026, was due to end of year updates that delayed processing.
  • TROPOMI-SENTINEL-5P, on January 2, 2026, was due to an overnight failure.
  • OMPS-SNPP, on January 5, 2026, is under investigation.
  • SMAP L-BAND RADIOMETER-SMAP, on January 5, 2026, due to jobs being retried for some reason, either manual or automatic.
  • TROPOMI-SENTINEL-5P, on January 5, 2026, was due to an overnight failure.
  • OMPS-SNPP, on January 8, 2026, is under investigation.
  • VIIRS-SNPP-Atmosphere, on January 8 and 9, 2026, was due to a mechanical issue.
  • VIIRS-NOAA-21-Land, on January 8, 2026, was due to a delay in the delivery of L0 data from EDOS.
  • VIIRS-NOAA-20-Atmosphere, on January 9, 2026, was due to a mechanical issue.

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 6 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 6 instruments (OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, TROPOMI-SENTINEL-5P, VIIRS-SNPP-Land, VIIRS-NOAA-20-Atmosphere, and VIIRS-NOAA-21-Land) were satisfied within 3 hours. OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, TROPOMI-SENTINEL-5P, VIIRS-SNPP-Land, VIIRS-NOAA-20-Atmosphere, and VIIRS-NOAA-21-Land over 94%, 88%, 94%, 78%, 73%, and 90% of the NRT data requests were satisfied within 3 hours, respectively.
