EOSDIS Science Data Metrics
Note:
1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 1.132 times the volume added to the archive per day.
LANCE Data Latency
Note:
1. Higher product latencies for:
- AIRS-AQUA on January 30, 2024, due to system maintenance.
- VIIRS-Suomi NPP (Land) on January 31, 2024, due to a SMD event that caused a data outage.
- VIIRS-JPSS1 (Atmosphere) on February 3, 2024, due to an outage because of a satellite anomaly. The data are reported to be unrecoverable.
Note:
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 two instruments (MODIS-AQUA and VIIRS-Suomi NPP (Land)) were satisfied within 3 hours. For MODIS-AQUA and VIIRS-Suomi NPP (Land), over 95% and 78% of the NRT data requests were satisfied within 3 hours, respectively.
