| Abstract | JPSS2 L1: PGE500 3.0.14, PGE501 3.0.35, PGE502 3.0.32, PGE502B 3.0.32, PGE560 2.0.5, PGE591 2.0.2, PGE595 2.0.9 Official processing/reprocessing of J2 C2 NASA L1 products using latest LUTs from calibration and geolocation teams. See attachments for details on LUTs to be used. |
| Problem Statement | Processing/reprocessing of JPSS2 (J2) data from beginning of mission to leading edge using calibration LUTs provided by VCST and geolocation LUTs from geolocation team. Anticipate start of data production week of 9/25/23. |
| Description of Change | Official processing/reprocessing of J2 C2 NASA L1 products using latest LUTs from calibration and geolocation teams. See attachments for details on LUTs to be used. |
| Products Affected | VJ201,VJ203[IMG|MOD|DNB],VJ202[IMG|MOD|DNB|OBC|GDC], VJ2T[011|030|034|037|SCI] |
| Software Affected | J2 L1: PGE500 3.0.14, PGE501 3.0.35, PGE502 3.0.32, PGE502B 3.0.32, PGE560 2.0.5, PGE591 2.0.2, PGE595 2.0.9 |
| Processing String to Receive the Change | J2 Forward Processing. J2 Reprocessing. |
| Downstream Product Effects | All VIIRS land products. |
| Data Granules to be Used for Science Testing | A science test was conducted for the GEO LUT to be used in this reprocessing. The calibration LUTs were also included in this test. All LUTs and PGEs also used in extended checkout test being run in AS4014. |
| Justification | Official J2 C2 product generation, marked as provisional, using the latest science codes and LUT combinations. |
| Effective Date for Implementation of Change | PGE595/L0 Splitter v2.0.9, PGE500/L1A 3.0.14, PGE501/Geo 3.0.35, and PGE502/L1B 3.0.32 will be put into use in both AS5299 for BOM and AS5200 for J2 CRD open and beyond. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved 09/21/2023. |
