| Abstract | PGE113N 6.1.24 The full set of C61 MAIAC changes have already been summarized in the PCR# 22-004. This PCR only highlights the key changes made for NRT processing. 1. Updated PGE113N loader module Perl script to do the following:
2. Created and installed the NRT specific MCD19A3DN ESDT. |
| Problem Statement | This PCR introduces the Collection 6.1 (C61) MAIAC suite of gridded products, MCD19A1N, MCD19A2N, and MCD19A3DN as part of the MODIS NRT processing. |
| Description of Change | The full set of C61 MAIAC changes have already been summarized in the PCR# 22-004. This PCR only highlights the key changes made for NRT processing. 1. Updated PGE113N loader module Perl script to do the following,
2. Created and installed the NRT specific MCD19A3DN ESDT |
| Products Affected | Daily C61 L3 MAIAC NRT gridded products, MCD19A1N, MCD19A2N, MCD19A3DN. |
| Software Affected | PGE113N 6.1.24 |
| Processing String to Receive the Change | Terra and Aqua Forward Processing. NRT |
| Downstream Product Effects | C61 NRT MAIAC MCD19A1N, MCD19A2N, and MCD19A3DN. |
| Data Granules to be Used for Science Testing | A series of science tests have been carried out to assess and fully confirm all production rule and science changes, in AS 1933. The outputs from this test were fully assessed and approved by LDOPE and the science team. |
| Justification | The C61 MAIAC NRT products will help maintain the continuity of this much needed science product from LANCE NRT, in line with previous Collection 6 (C6) products and reflect all the C61 science changes. |
| Effective Date for Implementation of Change | The aforementioned PGE113N version was put into operation on nrt4, starting 2023-04-19. The same will be made operational from nrt3, during the first week of May 2023. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved on 04/28/2023. Sudipta Sarkar implemented on 04/21/2023. |
