LANCE Data Latency

Note:
Higher product latencies for:

• VIIRS-NOAA-20 (Atmosphere) on March 14, 2024, due to servers’ cooling system failure
• IIRS-JPSS-1 (Land) on March 16, 2024, due to a configuration issue

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 three instruments (VIIRS-JPSS1(Land), VIIRS-SNPP (Land), and VIIRS-SNPP (Atmosphere)) were satisfied within 3 hours. For VIIRS-JPSS1(Land), VIIRS-SNPP (Land), and VIIRS-SNPP (Atmosphere), over 94%, 79%, and 93% of the NRT data requests were satisfied within 3 hours, respectively.
