LANCE Data Latency

Note:

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 six 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 (SMAP L-BAND RADIOMETER-SMAP, TROPOMI-SENTINEL-5P, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-NOAA-20-Atmosphere, and VIIRS-NOAA-21-Land) were satisfied within 3 hours. SMAP L-BAND RADIOMETER-SMAP, TROPOMI-SENTINEL-5P, VIIRS-NOAA-20-Land, VIIRS-SNPP-Land, VIIRS-NOAA-20-Atmosphere, and VIIRS-NOAA-21-Land over 86%, 91%, 93%, 79%, 84%, and 85% of the NRT data requests were satisfied within 3 hours, respectively.
