LANCE Data Latency
Note:
Higher product latencies for:
- VIIRS-SNPP-Land on September 30, 2024, due to GPS issues
- VIIRS-SNPP-Atmosphere October 2, 2024, due to not receiving OISST ancillary files from NCEI
- VIIRS-NOAA-20-Atmosphere October 2, 2024, due to not receiving OISST ancillary files from NCEI
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 five instruments (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 SMAP L-BAND RADIOMETER-SMAP, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-SNPP-Atmosphere, and VIIRS-NOAA-20-Atmosphere, over 85%, 89%, 80%, 94%, and 94% of the NRT data requests were satisfied within 3 hours, respectively.
