| Date | 2017-12-20 |
| Initiator | Lin, Guoging (Gary) |
| Abstract | PGE01 v6.1.3 -- Generated and integrated the new geolocation LUT |
| Problem Statement | Improvement to the geolocation accuracy of Aqua MODIS |
| Description of Change | Update to the geolocation LUT in PGE01 to improve geolocation accuracy by ~25m for Aqua MODIS. |
| Products Affected | MYD03, MYD03CP |
| Software Affected | PGE01 v6.1.3 MYD_PR03 |
| Processing String to Receive the Change | Aqua Reprocessing. |
| Downstream Product Effects | Geolocation accuracy improvement of 25m in C61 geolocation of Aqua MODIS compared to the C6. |
| Data Granules to be Used for Science Testing | Ran science test generating a month of data globally for the period 2015/324 - 2015/356 |
| Justification | Better accuracy in the Aqua MODIS geolocation when reprocessed using the new LUT. Recommend using the new LUT in the new C61 collection reprocessing, and in the C61 forward-processing as well, until another update planned mid-2018. |
| Effective Date for Implementation of Change | Completed. |
| Status | Major algorithm development completed. Gang Ye implemented 01/02/2018. |
