MODAPS PCR 11-012
| PCR Number | 11-012 |
|---|---|
| Date | 2011-01-24 |
| Initiator | Gang Ye and Zhengming Wan |
| Abstract | PGE16 for operation in C4.1; code update to fix metadata problem and to backup the UPD files daily instead of every 8-day; replaces the operational 4.4.4 version which failed in Oct 2010. |
| Problem Statement | Segmentation fault in mod11_lst2A1.c and mo11_listB1.c |
| Description of Change | Fix ArchiveMetadata exceeding limit of 65535 bytes in intermediate HDF filesFix LOCALINPUTGRANULEID exceeding the maximum length of 255Fix to PGE16D (mod11_listB1.c) for handling of ArchiveMetadata exceeding 65535bytes Back up MOD11UPD daily |
| Products Affected | MO[Y]D11_L2, MO[Y]D11A1, MO[Y]D11B1 |
| Software Affected | PGE16 v4.4.8 |
| Processing String to Receive the Change | Terra Forward, Terra Reprocessing, Aqua Forward, Aqua Reprocessing |
| Downstream Product Effects | None. |
| Data Granules to be Used for Science Testing | Test 8 days of Terra/Aqua data at MODAPS. No science change expected. |
| Justification | Without the fix the PGE failed to run to completion. Backing up the UPD daily would let MODAPS restart the process for the data day of PGE failure, instead of having to fall back to the prior 8-day boundary. |
| Effective Date for Implementation of Change | Completed. |
| Status | Sadashiva Devadiga approved on 1/24/2011. This is an internal PCR approved for documenting the verification of the successful testing of the PGE version. There is no change to the science code and so no further science testing is required. |
