ESDIS Weekly Metrics: April 27, 2023

EOSDIS Science Data Metrics

eosdis metrics 4-27-23


  1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 4.256 times the volume added to the archive per day.
  2. The increase on 17 Apr 2023 if from ORNL DAAC ingesting two products from AVIRIS.

LANCE Data Latency

lance metrics 1b 4-27-23


  1. Higher product latencies for:

    1. VIIRS-JPSS-1 (Atmosphere) and VIIRS-Suomi NPP (Atmosphere) on 16 Apr 2023, due to an expired ancillary file preventing the Cloud Mask from running for both Suomi NPP and NOAA-20. Other Level 2 products that rely on Cloud Mask as input were also delayed until the ancillary file issue was resolved.

    2. AIRS-Aqua on 16 Apr 2023, due to delay in processing AIRS NRT due to processing failures.

    3. MISR-TERRA on 20 Apr 2023, is being investigated. AIRS-AQUA on 10 Apr 2023, due to processing failures causing delays.

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

  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 seven instruments (AIRS-AQUA, MISR-TERRA, MODIS-AQUA, OMPS-Suomi NPP, VIIRS-Suomi NPP (Land), VIIRS-Suomi NPP (Atmosphere), and VIIRS-JPSS-1 (Atmosphere)) were satisfied within 3 hours. For AIRS-AQUA, MISR-TERRA, MODIS-AQUA, OMPS-Suomi NPP, VIIRS-Suomi NPP (Land), VIIRS-Suomi NPP (Atmosphere), and VIIRS-JPSS-1 (Atmosphere) over 94%, 94%, 95%, 94%, 73%, 94%, and 93% of the NRT data requests were satisfied within 3 hours, respectively.
