Now available! The 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 is now accessible via the CLASS web ordering system. The reprocessed data is located under their own data families listed on the drop down product menu. The date range which covers the reprocessing period for each instrument is:
The operational data received after the reprocessed date ranges uses the latest version of the reprocessing algorithm.
