Attention JPSS Data Users! (updated on 3/16/2022):CLASS is now receiving reprocessed Sensor Data Records (SDR) for all instruments flown on S-NPP and reprocessed Temperature Data Records (TDR) for the ATMS instrument flown on S-NPP. The date range which covers the reprocessing period for each instrument is:
- *ATMS SDR/TDR (2011-11-08 - 2019-10-15) - The complete record is now available under RPATMSSDR and RPATMSTDR (01/31/2022)
- *CrIS SDR (2012-02-20 - 2020-01-29) - The complete record is now available under RPCRISSDR (03/11/2022)
- *OMPS SDR (2012-01-30 - 2020-05-30) - The complete record is now available under RPOMPSSDR (03/16/2022)
- *VIIRS SDR (2012-01-02 - 2020-04-30)
At an ingest rate of 3TB per/day the completion date is estimated for June 2023. The VIIRS data is the largest volume by far and will be the last to ingest. Users can download the global data files from the ftp server at ftp-jpss.avl.class.noaa.gov under the STAR subfolder. The data will remain on the server for about 85 days. Searches for regional data on the individual search pages will remain disabled until the data are 100% available. Please contact the CLASS Helpdesk for details.
