ESDIS Weekly Metrics: July 8, 2024

Note:
1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 1.724 times the volume added to the archive per day.

LANCE Data Latency

Note:
Higher product latencies for:

• MLS-AURA on June 30, 2024, due to a delay in receiving data from the provider
• OMI-Aura on June 30 – July 2, 2024, due to broken metric scripts
• SMAP L-BAND RADIOMETER-SMAP on June 30 and July 3, 2024, due to a delay in receiving science data from the spacecraft and maintenance, respectively

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.  
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 (AMSR2-GCOM-W1, OMI-AURA, OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, VIIRS-SNPP-Land, and VIIRS-SNPP-Atmosphere) were satisfied within 3 hours. For AMSR2-GCOM-W1, OMI-AURA, OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, VIIRS-SNPP-Land, and VIIRS-SNPP-Atmosphere, over 94%, 35%, 93% 74%, 78%, and 94% of the NRT data requests were satisfied within 3 hours, respectively.
