EOSDIS Science Data Metrics
1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 4.2 times the volume added to the archive per day.
LANCE Data Latency
- Higher product latencies for VIIRS-JPSS-1 (Atmosphere) and VIIRS-Souomi NPP (Atmosphere) on 01 February 2022 were due a new Science Data Transfer Protocol (SDTP) ingest method for Level 0 (L0) files that continues to be slower than the old ingest method.
- 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.
- 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).
- Over the last four weeks, over 95% of NRT data requests for all instruments except for six instruments (MISR-TERRA, MODIS-AQUA, VIIRS-JPSS-1 (Land), VIIRS-Suomi NPP (Land), VIIRS-Suomi NPP (Atmosphere), VIIRS-NOAA-20 (Atmosphere)) were satisfied within 3 hours. For MISR-TERRA, MODIS-AQUA, VIIRS-JPSS-1 (Land), VIIRS-Suomi NPP (Land), VIIRS-Suomi NPP (Atmosphere), and VIIRS-NOAA-20 (Atmosphere) over 93%, 92%, 94%, 78%, 90% and 92% of the NRT data requests were satisfied within 3 hours, respectively.
