Note:

  1. Higher product latencies for
    1. VIIRS-Suomi NPP (Land) on 19 August 2021 are due to delay in the delivery of L0 data.
    2. MODIS-AQUA on 16 August 2021 are due to bad Aqua GBAD data received on 15 August 2021

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 (MODIS-AQUA, OMPS-Suomi NPP and VIIRS-Suomi NPP (Land)) were satisfied within 3 hours. For MODIS-AQUA, OMPS-Suomi NPP and VIIRS-Suomi NPP (Land) over 93%, 91% and 69% of the NRT data requests were satisfied within 3 hours, respectively.
