    LANCE Data Latency

    LANCE Metrics 1 1-14-21


    1. Higher product latencies for
      1. MODIS-AQUA on March 29, 2021 are due to delay in receiving ancillary data for L2G products by MODAPSNRT
      2. MISR-TERRA on April 01, 2021 are due to additional system issues at LARCNRT.
    2. There is no data for MOPITT-TERRA products from April 01-03, 2021 due to MOPITT’s annual hot calibration activity.

    LANCE Metrics 2 1-14-21


    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 (MISR-TERRA, OMPS-Suomi NPP and VIIRS-Suomi NPP (Land)) were satisfied within 3 hours. For MISR-TERRA, OMPS-Suomi NPP and VIIRS-Suomi NPP (Land) over 89%, 93% and 73% of the NRT data requests were satisfied within 3 hours, respectively.
