LANCE Data Latency

Note:

Higher product latencies for:

• VIIRS-SNPP-Land on November 4, 2024, due to a delay in processing
• VIIRS-NOAA-20-Land on November 8, 2024, due to a delay in processing

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 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 (AIRS-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 AIRS-AQUA, SMAP L-BAND RADIOMETER-SMAP, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-SNPP-Atmosphere, and VIIRS-NOAA-20-Atmosphere, over 94%, 75%, 93%, 80%, 85%, and 85% of the NRT data requests were satisfied within 3 hours, respectively.
