| Abstract | PGE03 6.1.4; PGE06 6.1.7 Add new set of Cloud products in regular and polar projections. |
| Problem Statement | Expecting changes to be made to the GDAS atmospheric profile that are used as ancillary data in the cloud top properties algorithm (MxD06_CT). To accommodate the changes in GDAS the MODIS Cloud Mask algorithm (PGE03) and the Cloud Top Properties algorithm (PGE06) had to be modified. |
| Description of Change | Changes were made to gfs_routines.c and adjo3.c to account for modifications in GDAS input files. The numbers of levels have increased and RH and O3 levels are no longer contiguous with temperature levels. This required logic changes in the two routines. |
| Products Affected | MxD35_L2, MxD06_L2, MxD08_D3 and MxD08_M3 |
| Software Affected | PGE03 6.1.3; PGE06 6.1.7 |
| Processing String to Receive the Change | Terra and Aqua Forward Reprocessing. NRT |
| Downstream Product Effects | MxD06_L2, MxD07_L2 and MxD08_D3, MxD08_E3, and MxD08_M3 |
| Data Granules to be Used for Science Testing | Science test generated nearly a month of Terra and Aqua data and were verified for correctness. |
| Justification | Changes were made to gfs_routines.c and adjo3.c to account for modifications in GDAS input files. The numbers of levels have increased and RH and O3 levels are no longer contiguous with temperature levels. This required logic changes in the two routines |
| Effective Date for Implementation of Change | February 1, 2021 |
| Status | Major algorithm development completed. Steve Platnick approved 02/01/2021. Gang Ye implemented 02/01/2021. |
