LRO: DIVINER

March 15, 2023. LRO Release 53 includes new Diviner EDR data acquired between September 16 and December 15, 2022, and backlogged RDR data acquired between December 16, 2020, and June 30, 2021. PDS4 labels are provided for all new Diviner data products.

All previously released Diviner calibrated (RDR) data have been migrated to the PDS4 standard. The previously released Diviner derived data (GCP, GDR, PRP) and the Diviner EDRs are expected to be migrated by Release 54, June 15, 2023.

See lro_diviner_pds4_notes.pdf, release_notes.txt (EDR), and release_notes.txt (RDR) for details.

The release of Diviner RDR products has been delayed in order to correct a data processing error recently discovered. Since April 17, 2019 at 12:00, almost all
(99.25%) Diviner RDR products have been missing temperature brightness data for the solar channels 1 and 2. A small amount of temperature brightness data in non-solar channels (channels 3 through 9) is also missing since this date. It's only about 1.1%, but it is significant because prior to this date almost none of it was missing. JPL is currently tracking down the reason for the missing data and hopes to have a fix for it fairly soon. When it is fixed, the Diviner team will redeliver all the RDR products since
April 17, 2019.

Records with missing brightness temperature data have the value -9999 in the "tb" column (column 24) of the Diviner RDR data product. The missing data is the result of processing errors, and is not due to a fault with the instrument. The EDR data products are not affected by these errors.
