| Abstract | PGE400 v6.0.9; PGE411 v6.0.7; PGE412 v6.0.7; PGE421 v6.0.7; PGE422 v6.0.7 Update pre_process_*VI.c , timesat_*VI.f90, timesate_*VI_2nd.f90, gapfill_*VI.c. do_gapfill.csh Updated code to work with collection 6 input data. |
| Problem Statement | Generate the NACP products using the input products generated in the C6 processing of MODIS. |
| Description of Change | Removed the dependency on internal snow mask. Now the growing season cut off is simply land surface temperature. |
| Products Affected | MOD15A2GFS, MOD15A2PHN, MOD09A1G_EVI, MOD09A1G_NDVI, MOD09A1P_EVI, MOD09A1P_NDVI, MOD09Q1G_EVI, MOD09Q1G_NDVI, MOD09Q1P_EVI, MOD09Q1P_NDVI |
| Software Affected | PGE400 v6.0.9; PGE411 v6.0.7; PGE412 v6.0.7; PGE421 v6.0.7; PGE422 v6.0.7 |
| Processing String to Receive the Change | Terra and Aqua Forward Processing, Terra and Aqua Reprocessing |
| Downstream Product Effects | None |
| Data Granules to be Used for Science Testing | Ran science test generating the product of year 2016. |
| Justification | After upgrading to C6, the input data format/resolution changed. The internal snow mask does not work properly which introduced error in detecting growing season (shorten the growing season significantly). |
| Effective Date for Implementation of Change | Completed. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved 09/26/2018. Gang Ye approved on 09/27/2018. |
