| Abstract | PGE500 3.0.12, PGE595 2.0.7, PGE599 1.0.11 For all science changes, refer to section "Description of Change". |
| Problem Statement | Revised PGE perl scripts for PGE500/L1A, PGE595/L0 Splitter, and PGE599/Kalman Filter, to eliminate references to SDPToolkit in environment setup to prevent errors on Ubuntu minions. The toolkit is not used by VIIRS PGEs and this revision is consistent with all other VIIRS PGEs updated and tested for Ubuntu GitLab; was accidentally left in for these three PGEs. PGEs are in use in SNPP C2 and JPSS1 C2.1 L1 forward processing. |
| Description of Change | As part of migrating to gitlab, the PGE perl scripts were revised to eliminate references to SDPToolkit versions. However, PGE500, PGE595 and PGE599 were some of the first to be migrated to GitLab and this particular revision was missed for these PGEs. In refining Ubuntu minions to only have the gitlab SDPToolkit present, we realized these PGE perl script needed revising. Making this change does not impact the science code, but will help prevent potential failures if attempts are made to access non-existent SDPToolkit versions during call for MODAPS PGE environment setup. |
| Products Affected | V[NP|J1]01, V[NP|J1]T[000|008|011|SCI], VNPT11K |
| Software Affected | PGE500 3.0.12, PGE595 2.0.7, PGE599 1.0.11 |
| Processing String to Receive the Change | S-NPP Forward Processing. J1 Forward Processing. |
| Downstream Product Effects | All VIIRS land products |
| Data Granules to be Used for Science Testing | A science test was not conducted, however Ubuntu command line and lp1 instance tests were executed to verify successful execution on systems where older SDPToolkit versions had been eliminated. |
| Justification | For consistency and to provent potential errors. |
| Effective Date for Implementation of Change | Promotion of PGE500 v3.0.12, PGE595 v2.0.7, and PGE599 v1.0.11 to go into ops6 forward processing for SNPP C2 and JPSS1 C2.1 starting 4/12/22 |
