1. The volume distributed to end users per day, as a running average over the last 4 weeks, is ~ 3.3 times the volume added to the archive per day.

LANCE Data Latency

LANCE Metrics 1 1-14-21


  1. Higher product latencies for
  2. AIRS-AQUA on May 11, 2021, are due to system upgrades at GESDISCNRT
  3. OMPS-Suomi NPP on May 12, 2021, are due to delay in receiving L0 data by OMINRT
  4. VIIRS-Suomi NPP (Land) on May 12 and 15, 2021, are due to delay in receiving L0 data by MODAPSNRT.

LANCE Metrics 2 1-14-21


  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 on-line 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 four weeks, over 96% of NRT data requests for all instruments except for three instruments (MODIS-AQUA, OMPS-Suomi NPP and VIIRS-Suomi NPP (Land)) were satisfied within 3 hours. For MODIS-AQUA, OMPS-Suomi NPP and VIIRS-Suomi NPP (Land) over 94%, 92% and 71% of the NRT data requests were satisfied within 3 hours, respectively.
