| Abstract | PGE128 v6.0.11. Update the script with command hrepack for compressing the product files and add the perl script MOD_PR02PCCRS.pl for producing the coarse product in PGE128. |
| Problem Statement | Generated polarization corrected product files were relatively large in size since the files were not compressed. Coarse product files required for generating the browse images for LDOPE were not generated by the PGE. |
| Description of Change | Compress product files MxD02PCH[Q][1]KM using HDF tool hrepack. Add the shared source code to generate the coarse products of polarization corrected L1B files, and optionally archive coarse product. |
| Products Affected | MxD02PC1KM, MxD02PCHKM, MxD02PCQKM |
| Software Affected | PGE128 v6.0.11 |
| Processing String to Receive the Change | Terra Reprocessing and Aqua Reprocessing |
| Downstream Product Effects | None. |
| Data Granules to be Used for Science Testing | Process two global days of Aqua and Terra on the MODAPS test system using the C6 L1B as input.2010-059 |
| Justification | Compressing of the files reduces the file size freeing up disk space on the system. Coarse products are required for generating the global browse images used in the quality assessment of the product at LDOPE. |
| Effective Date for Implementation of Change | Completed. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved on 06/29/2015. Gang Ye approved on 06/29/2015. |
