| Initiator | Dr. Zhengming Wan |
| Abstract | PGE115 v6.3.1. Update mod11b3_6km.c to use PGE start time to create the local granule id. |
| Problem Statement | Monthly LST products are generated for days other than the beginning of the month. |
| Description of Change | Update the PGE to use the PGE start time to create the local granule id instead of the start date from the input. Operational version of the PGE used the start date of input. Missing inputs from one or more starting days of the month resulted in the products being generated with incorrect data day in local granule id. |
| Products Affected | MxD11B3 |
| Software Affected | PGE115 v6.3.1 |
| Processing String to Receive the Change | Terra Reprocessing and Aqua Reprocessing |
| Downstream Product Effects | None. |
| Data Granules to be Used for Science Testing | Process the monthly product for the Terra day 2001182. In operational processing products were created for days 2001183 and 2001184 because of missing data for day 2001182.2010-059 |
| Justification | Without this fix, monthly products would be created for the beginning day of the data in the month, instead of creating the product for the first day of the month. Monthly products with incorrect granule id will be considered invalid and will not be archived or distributed. Since many tiles may have been created with invalid granule ids, a reprocessing of the product from the beginning of the mission is requested. |
| Effective Date for Implementation of Change | Completed. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved on 06/05/2015. Michael King approved on 06/09/2015. |
