| Initiator | Bill Ridgway |
| Abstract | To implement updates in PGE06 v6.0.81 code and File Spec only. |
| Problem Statement | Version 6.0.80 to correct:· A few tau > 150 solutions possible in ASL; need to filter them out· Minor differences in 32-bit and 64-bit system products as well as Mac/Linux products· Need additional metadata descriptor to clarify parameter descriptions· Memory leak found in ASL codeVersion 6.0.81 adds logging functionality. |
| Description of Change | · Altered the alternate solution logic tau = 150 boundary solution so that integer re’s no longer appear in non-RFM output. A very minor impact, mainly at high latitudes.· Altered the code so that cloud phase no longer attempts to process the last line of data that is not retrieved due to cloud mask issues. This was source of apparent inconsistency between 32 and 64 bit. No science impact.· Added some library array initialization in the interpolate_libraries module so that results no longer show some numerical noise between Mac and Linux. Very minor science impact if any.· Altered filespec so that metadata describing SDS contents is added to the stored scattering properties SDSs: ce, g and omega0. No science impact.· Located and remedied a memory leak in ASL_boundary() subroutine of item 1. A local array was not being deallocated when exit-on-error. No science impact.· - Logging functionality will allow us to create a database of key product metadata for QA support |
| Products Affected | MYD06_L2 and MOD06_L2 |
| Software Affected | PGE06 v6.0.81 |
| Processing String to Receive the Change | Terra Forward, Terra Reprocessing, Aqua Forward, Aqua Reprocessing |
| Downstream Product Effects | Subset products (PGE83), Browse products (PGE89, PGE108) and Level 3 MYD08_*3 products. |
| Data Granules to be Used for Science Testing | Successful integration was verified with a 2-day Terra+Aqua Science Test in AS 1217. No testing of logging functionality was required beyond unit tests.2010-059 |
| Justification | Fixed known flaws. Minimal science impact. Applied for Aqua 2013/2014 and Terra C6 (planned). |
| Effective Date for Implementation of Change | Sept 15 for Aqua 2013/2014 and forward reprocessing. Reprocessing for the full Terra mission. |
| Status | Science test completed. Steve Platnick approved on 11/13/2014. Michael King approved on 11/13/2014. |
