| Abstract | PGE132 V6.0.33 -- Modified the PGE_StartTime/EndTime in the following command from custom values (consistent with the modified File date for PGE113) to the regular PGE Time. Eval => "if ( CountPGE('${PreviousPGE[$i]}',{Tile=>undef,PGE_StartTime=>'$ri->{PGE_StartTime}',PGE_EndTime=>'$ri->{PGE_EndTime};',Profile=>1}) >= $TileTotal[$i] || IsForced ) { |
| Problem Statement | There was an issue with PGE132 running too early because the dates listed for the "File" were different from the date listed for the "PGE" in the database. So, when CountPGE() was looking to make sure the inputs ran, they would come up as ran, but there would be no output files to process. So, the code would end up in NoRun prematurely. |
| Description of Change | PGE132 V6.0.33 has been updated to use different dates when referring to "File" and "PGE" in the LoaderModule. |
| Products Affected | MODIS C6 Land L3 GIBS products, specifically the MCG19A3 products. |
| Software Affected | PGE132 V6.0.33 |
| Processing String to Receive the Change | Terra and Aqua Forward Processing. NRT. |
| Downstream Product Effects | None. |
| Data Granules to be Used for Science Testing | A science test was run from C6 forward production in AS 1879 and all products confirmed by LDOPE. |
| Justification | The PGE132, operating in the OPS and NRT streams, for C6, were not-producing GIBS Land L3 images for MCG19A3 as it was not checking the correct upstream PGE. |
| Effective Date for Implementation of Change | As soon as possible from NRT (nrt3/4) and from C6 forward production on OPS. |
| Status | Major algorithm development completed. Gang Ye approved on 01/06/2022. |
