Note: Higher product latencies for...

  • TROPOMI-SENTINEL-5P, on March 9-10 and March 14 were due to failures; and
  • VIIRS-NOAA-21-Land, on March 12 were due to EDOS downtime, which impacted the L0 data coming into the NRT system in a timely manner.

Notes:

  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 to the granule being ready on-line for users to download.  
  2. Duration covered by the data for a granule is defined differently for four different instruments (e.g., MODIS granules are 5 minutes long, while OMI NRT granules are 13 to 136 minutes long).
  3. Over the past four weeks, more than 95% of near-real time (NRT) data requests for nearly all instruments were satisfied within 3 hours. The exceptions were TROPOMI-SENTINEL-5P and VIIRS-SNPP-Land, which had rates of 94% and 78%, respectively, of NRT data requests being satisfied within 3 hours.
