    1. Higher product latencies for
      1. MODIS-AQUA on December 30, 2020 are due to delay in receiving ancillary data by MODAPSNRT
      2. VIIRS-SNPP (Land) on January 01, 2021 are due to delay in receiving L0 data by MODAPSNRT.

    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 two instruments (OMPS-SNPP and VIIRS-SNPP (Land)) were satisfied within 3 hours. For OMPS-SNPP and VIIRS-SNPP (Land) over 93% and 73% of the NRT data requests were satisfied within 3 hours respectively.
