| Abstract | PGE120 V6.1.13 -- Commenting out the portions of the code related to Night time continuous scrolling, tested in v 6.1.10 and 6.1.11. And mistakenly used in 6.1.12. |
| Problem Statement | Certain changes, made to PGE120 to enable continuous nighttime scrolling across the dateline, for certain L1 and L2 nighttime products were meant for testing but were inadvertently put in production. |
| Description of Change | The C61 PGE120 V6.1.13 was updated to roll back the continuous nighttime scrolling changes, made for certain L1 and L2 swath products. |
| Products Affected | MODIS C61 L2 JPL LST (MxD21) from STD and NRT |
| Software Affected | PGE120 V6.1.13 |
| Processing String to Receive the Change | Terra and Aqua Forward Processing. Terra and Aqua Reprocessing. NRT |
| Downstream Product Effects | None |
| Data Granules to be Used for Science Testing | The PGE120 V6.1.13 have been tested by running over an extended period from nrt4 test instance and have been confirmed from the GIBS WorldView test instance. |
| Justification | This updates the PGE120 to rollback certain test only changes, to allow for continuous night time scrolling across the datelines, that were inadvertently placed in production. |
| Effective Date for Implementation of Change | Has been in effect on nrt4 since June 13, 2022. Will be placed on nrt3 and ops starting June 14, 2022. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved on 07/15/2022. Sudipta Sarkar approved on 07/15/2022. |
