LANCE Data Latency

Note:

Higher product latencies for:

• OMPS-SNPP on February 11, 2025, due to receiving Level 0 data late.
• VIIRS-SNPP-Land on February 14, 2025, due to receiving bad L0.
• VIIRS-NOAA-20-Land on February 15, 2025, due to receiving bad L0.

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 online 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 4 weeks, over 95% of NRT data requests for all instruments except for 3 instruments (OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, and VIIRS-SNPP-Land) were satisfied within 3 hours. OMPS-SNPP, SMAP L-BAND RADIOMETER-SMAP, and VIIRS-SNPP-Land over 88%, 82%, and 76% of the NRT data requests were satisfied within 3 hours, respectively.
