Graph of EOSDIS metrics from September 23, 2021

Note: 1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 3 times the volume added to the archive per day.

Note: Higher product latencies for MODIS-AQUA on 14 to 17 September 2021 are due to delay in L0 data.

  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 95% 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 91%, 93% and 71% of the NRT data requests were satisfied within 3 hours, respectively.
