EOSDIS Science Data Metrics
- The volume distributed to end users per day, as a running average over the last 4 weeks, is 4.493 times the volume added to the archive per day.
LANCE Data Latency
Higher product latencies for VIIRS-JPSS-1 (Land) on 4 Jan 2023, due to a J1 maneuver that caused the geolocation code to fail in the processing of granules and went unnoticed from 1/2/2022 to 1/4/2022. Multiple products were affected.
No LIS-ISS reported in the plot due to an error in our metrics system.
- 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 four instruments (OMPS-Suomi NPP, VIIRS-JPSS-1 (Land), VIIRS-Suomi NPP (Land), and VIIRS-NOAA-20 (Atmosphere)) were satisfied within 3 hours. For OMPS-Suomi NPP, VIIRS-JPSS-1 (Land), VIIRS-Suomi NPP (Land), and VIIRS-NOAA-20 (Atmosphere) over 94%, 91%, 78%, and 94% of the NRT data requests were satisfied within 3 hours, respectively.
