| Abstract | To implement updates to PGE11 v5.3.38 which improve the CMG intermediate products that include orbital data with maneuvers in them. |
| Problem Statement | Orbits with maneuvers were generating segmentation faults during the cloud shadow algorithm, which impacted the CMG intermediate products of MOD_PR09.exe, making them useless. No other products were affected |
| Description of Change | The addition of an algorithm for recognizing which granules were obtained during an orbital maneuver and rejecting them from the CMG intermediate product and cloud shadow algorithm. |
| Products Affected | The CMG intermediate products MOD09IDT, MOD09IDS, and MOD09IDN. |
| Software Affected | PGE11 v5.3.38 |
| Processing String to Receive the Change | Terra Forward, Aqua Forward |
| Downstream Product Effects | MOD09CMG (product of MOD_PR09C.exe in PGE75) |
| Data Granules to be Used for Science Testing | Run 1-day global test for data day 2014-248 and 2010-0592010-059 |
| Justification | This change improves the MOD09CMG product by including data from orbits that have had maneuvers in them. |
| Effective Date for Implementation of Change | Completed. |
| Status | Algorithm development and testing completed. Sadashiva Devadiga approved on 09/30/2014. Michael King approved on 10/02/2014. |
