Note:
1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 1.710 times the volume added to the archive per day.

LANCE Data Latency

Note:
1. Higher product latencies for:

• MLS-AURA on Feb 13 and 14, 2024, due to some system processing issues.
• VIIRS-SUOMI NPP and VIIRS-NOAA-20 on Feb 15-16, 2024, due to processing delays.

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 two instruments (MODIS-AQUA, and VIIRS-SNPP (Land)) were satisfied within 3 hours. For MODIS-AQUA and VIIRS-SNPP (Land), over 92% and 79% of the NRT data requests were satisfied within 3 hours, respectively.
