| Initiator | Carol Davidson |
| Abstract | PGE556 2.0.4, PGE557 2.0.4 Revised NPP_PR46A3 the output.c to revise metadata attributes for quality flags, latitude, and longitude, datasets. No science/data values were changed, just the attributes describing the values so that the information is more accurate. |
| Problem Statement | C2 Monthly and Yearly LBAN, VNP46A3, VNP46A4, VJ146A3 and VJ146A4, were flagged as needing some metadata corrections, similar to those put into PGE554 (PCR 24-016) |
| Description of Change | Revised NPP_PR46A3 the output.c to revise metadata attributes for quality flags, latitude, and longitude, datasets. No science/data values were changed, just the attributes describing the values so that the information is more accurate. |
| Products Affected | VNP46A3, VJ146A3, VNP46A4, VJ146A4 |
| Software Affected | PGE556 2.0.4, PGE557 2.0.4 |
| Processing String to Receive the Change | S-NPP Forward Processing. S-NPP Reprocessing. J1 Foward Processing. J1 Reprocessing. |
| Downstream Product Effects | None |
| Data Granules to be Used for Science Testing | A science test was conducted of PGE556 2.0.4-0 and PGE557 2.0.4-0 and results reviewed by LDOPE and the LBAN science team. |
| Justification | Correction requested by LDOPE after review of data found the discrepancies for assorted dataset attributes. |
| Effective Date for Implementation of Change | PGE556 2.0.4 and PGE557 2.0.4 were installed for use on 12/9/2024. PGE556 will be used for reprocessing 2015 onward for SNPP, and PGE557 will be used for reprocessing 2014 onward for SNPP. All J1 reprocessing for these products will use the new versions of PGE556 and PGE557 as it has not yet been run. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved 12/12/2024. Sudipta Sakar implemented 12/09/2024. |
