ESDIS Weekly Metrics: February 23, 2023

EOSDIS Science Data Metrics

EOSDIS Metrics 2-23-23


  1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 3.823 times the volume added to the archive per day.

LANCE Data Latency

LANCE Metrics 1 2-23-23
LANCE Metrics 1b 2-23-23


  1. Higher product latencies for:

    1. MISR-TERRA on 17 Feb 2023, due to lingering OS upgrade issues on LANCE, causing delays.

    2. OMPS-Suomi NPP on 18 Feb 2023, due to late Level 0 (L0) Earth Observing System (EOS) Data and Operations System (EDOS) data.

    3. MODIS-TERRA and VIIRS-Suomi NPP (Land) on 17 Feb 2023 and 18 Feb 2023 respectively, due to errors in upstream L1B Terra from missing Lookup Tables (LUTs).

  2. No LIS-ISS reported in the plot due to an error in our metrics system.

LANCE Metrics 2 2-23-23


  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 two instruments (AIRS-AQUA, and VIIRS-Suomi NPP (Land)) were satisfied within 3 hours. For AIRS-AQUA, and VIIRS-Suomi NPP (Land) over 93%, and 79% of the NRT data requests were satisfied within 3 hours, respectively.
