ESDIS Weekly Metrics: October 14, 2024

Note:

The volume distributed to end users per day, as a running average over the last 4 weeks, is 3.142 times the volume added to the archive per day.

LANCE Data Latency

Note:

Higher product latencies for:
- VIIRS-NOAA-20-Land on October 6 and 10-11, 2024, due to ongoing maintenance activities in McMurdo, and that caused delay in processing completing
- AMSR2-GCOM-W1 on October 7, 2024, due to maintenance by JAXA (Japan Aerospace Exploration Agency)
- SMAP L-BAND RADIOMETER-SMAP on October 7-8, 2024, due to backfilling gaps after removing bad sea surface temperature (SST) ancillary files
- MODIS-AQUA on October 10, 2024, due to ongoing issues with MODIS Aqua Level 0 and affects of the solar storm the previous week
- MODIS-TERRA on October 10, 2024, due to Terra and Aqua combined products affected for their dependency on Aqua
- VIIRS-NOAA-20-Atmosphere on October 10, 2024, due to missing NOAA20 Level 0 files
- VIIRS-SNPP-Land on October 11, 2024, due to ongoing maintenance activities in McMurdo, and that caused delay in processing completing

Note:

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 four instruments (SMAP L-BAND RADIOMETER-SMAP, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-SNPP-Atmosphere, and VIIRS-NOAA-20-Atmosphere) were satisfied within 3 hours. For SMAP L-BAND RADIOMETER-SMAP, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-SNPP-Atmosphere, and VIIRS-NOAA-20-Atmosphere, over 79%, 85%, 79%, 92%, and 93% of the NRT data requests were satisfied within 3 hours, respectively.
