ESDIS Weekly Metrics: November 04, 2021

EOSDIS Science Data Metrics

Total data ingest, archive, and distribution at EOSDIS Data Centers, 4-week rolling chart

Note:

1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 3.2 times the volume added to the archive per day.

LANCE Data Latency

Four-week LANCE-wide latency and distribution trend for Level 0, 1, 2 products

Note:

  1. Higher product latencies for AMSR2-GCOM-W1 on 28 October 2021 are due to JAXA being down for maintenance. The product generation resumed later the same day.
Cumulative four weeks latency for LANCE Levels 0, 1, 2 products

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 on-line for users to download. 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). 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 93%, 94% and 72% of the NRT data requests were satisfied within 3 hours, respectively.
