ESDIS Weekly Metrics: October 28, 2024

Note:

The volume distributed to end users per day, as a running average over the last 4 weeks, is 2.376 times the volume added to the archive per day.

Note:

Higher product latencies for:

1. SMAP L-BAND RADIOMETER-SMAP on October 21-22 and 23, 2024, due to bad SMAP files and downtime for system maintenance, respectively.

2. VIIRS-NOAA-20-Atmosphere and VIIRS-SNPP-Atmosphere on October 22 and 24, 2024, due to delays in ancillary files (October 22) and production latency issues due to an internal system change (October 24).

Notes:

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 online 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 six instruments (MODIS-AQUA, 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 MODIS-AQUA, SMAP L-BAND RADIOMETER-SMAP, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-SNPP-Atmosphere, and VIIRS-NOAA-20-Atmosphere, over 94%, 70%, 86%, 78%, 79%, and 79% of the NRT data requests were satisfied within 3 hours, respectively.
