LANCE Data Latency

Note:
Higher product latencies for:

• VIIRS-SNPP (Land) on February 26, 2024, due to maintenance.
• AMSR2-GCOM-W1 on February 27, 2024, due to some sporadic delays with the L1R input data.

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 four instruments (MLS-AURA, VIIRS-SNPP (Land), VIIRS-SNPP (Atmosphere), and VIIRS-NOAA-20 (Atmosphere)) were satisfied within 3 hours. For MLS-AURA, VIIRS-SNPP (Land), VIIRS-SNPP (Atmosphere), and VIIRS-NOAA-20 (Atmosphere), over 92%, 80%,92% and 93% of the NRT data requests were satisfied within 3 hours, respectively.
