| Abstract | PGE157 6.1.6; PGE36[G] 6.1.4; PGE37[G] 6.1.4; PGE38[G] 6.1.4 Most of the processes for generation of these gap-filled products for C61 are similar to C6 (ref: PCR-19-018, 19-019). The following are the additional improvements for C61: 1. Enable the archiving of the daily rolling intermediate files at every "n-day" interval. |
| Problem Statement | Start generation the gap-filled year-end improved versions of MxD15 and MxD17 products as part of C61 re-processing. |
| Description of Change | Most of the processes for generation of these gap-filled products for C61 are similar to C6 (ref: PCR-19-018, 19-019). The following are the additional improvements for C61. 1. Small bug-fixes to different processes based on observations from the existing C6 products. 2. Enable the archiving of the daily rolling intermediate files at every "n-day" interval. |
| Products Affected | 8-day gap filled LAI-FPAR, 8-day and annual gap filled GPP/NPP |
| Software Affected | PGE157 6.1.6; PGE36[G] 6.1.4; PGE37[G] 6.1.4; PGE38[G] 6.1.4 |
| Processing String to Receive the Change | Terra and Aqua Forward Processing. Terra and Aqua Forward Reprocessing. |
| Downstream Product Effects | None |
| Data Granules to be Used for Science Testing | A science test was conducted to confirm the successful generation of all C61 gap-filled year-end MxD15A2HGF and MxD17A[2|3] products |
| Justification | This PCR affirms operational readiness of the PGE suite for generation of C61 gap-filled products GPP/NPP products. The year-end gap-filled products will be produced for the full mission period except in forward and considered the best quality science product compared to the operational products in the forward processing that would be generated using the operational LAI/FPAR product (as in C6) and the Climatology LAI/FPAR as back up to the operational LAI/FPAR product in the C61. |
| Effective Date for Implementation of Change | C61 specific PGE157, PGE117/118/119 and PGE36/37/38 were inducted for C61 re-processing as of 04/30/2020 |
| Status | Major algorithm development completed. Chris Justice approved on 07/28/2020. Sadashiva Devadiga approved on 07/23/2020. Gang Ye approved on 07/23/2020. |
