ESDIS Weekly Metrics: January 14, 2021

EOSDIS Science Data Metrics

EOSDIS Metrics 1-14-21

Note:

1. The volume distributed to end users per day, as a running average over the last 4 weeks, is ~ 3.5 times the volume added to the archive per day.

2. Higher distribution data volume from January 05-07, 2021 is primarily due to distribution of SENTINEL-1A/1B data by ASF DAAC and MODIS and VIIRS data by LAADS DAAC.


LANCE Data Latency

LANCE Metrics 1 1-14-21

Note:

  1. Higher product latencies for
    1. MODIS-TERRA on January 04, 2021 and MODIS-AQUA on January 08, 2021 are due to issues with input data at MODAPSNRT
    2. VIIRS-SNPP (Atmosphere) on January 04, 2021 are due to issues with L0 data that were received by ASIPSNRT.

LANCE Metrics 2 1-14-21

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 three instruments (OMPS-SNPP, VIIRS-SNPP (Land) and VIIRS-SNPP (Atmosphere)) were satisfied within 3 hours. For OMPS-SNPP, VIIRS-SNPP (Land) and VIIRS-SNPP (Atmosphere) over 93%, 73% and 91% of the NRT data requests were satisfied within 3 hours, respectively.

Metrics from previous weeks are organized by week, and users can access the ESDIS Weekly Metrics Archive.
