| Abstract | To implement updates in PGE03 v6.0.40 and v6.0.40_1 for Loader Module bug fixes properly implementing production rules for GDAS ancillary for night granule profiles (M[O/Y]D07_L2). |
| Problem Statement | Flawed MOD07_L2/MYD07_L2 profile products were found in about half of processed night granules. The incorrect GDAS ancillary data file was read in each case. Code bug fix is needed to properly implement production rules for GDAS ancillary. |
| Description of Change | Updated PGE03 Loader Module to correct bug and check for defined values before using them. Custom re-processing version (40_1) runs only on night granules -- skips processing if DayNightFlag is not Night. |
| Products Affected | MOD07_L2/MYD07_L2 Profile product |
| Software Affected | PGE03 v6.0.40, PGE03 v6.0.40_1 |
| Processing String to Receive the Change | Terra Forward, Terra Reprocessing, Aqua Forward, Aqua Reprocessing |
| Downstream Product Effects | MYD07_L2 is used to produce MYD05_L2, MYDATML2 and Atmosphere L3 products.Land processing also uses MOD07_L2/MYD07_L2 |
| Data Granules to be Used for Science Testing | Data Granules used for Science Testing: Atmosphere products were generated for April 2005.2010-059 |
| Justification | Required bug fix to use correct ancillary input file. |
| Effective Date for Implementation of Change | ASAP for Aqua reprocessing and forward processing. Required for Terra reprocessing later in July. |
| Status | Algorithm development and testing completed. Steve Platnick and Sadashiva Devadiga approved on 7/11/2014. |
