EOSDIS Science Data Metrics
- The volume distributed to end users per day, as a running average over the last 4 weeks, is ~ 7.1 times the volume added to the archive per day.
- Higher distribution data volume from May 30 – Jun 2, is primarily due to distribution of MODIS-AQUA data by LAADS DAAC.
LANCE Data Latency
- Higher product latencies for VIIRS-Suomi NPP (Atmosphere) on Jun 3 are due to system upgrade at ASIPNRT.
- 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 96% of NRT data requests for all instruments except for four instruments (MODIS-AQUA, MISR-TERRA, OMPS-Suomi NPP and VIIRS-Suomi NPP (Land)) were satisfied within 3 hours. For MODIS-AQUA, MISR-TERRA, OMPS-Suomi NPP and VIIRS-Suomi NPP (Land) over 94%, 85%, 92% and 71% of the NRT data requests were satisfied within 3 hours, respectively.
