Abstract | Fix to correct the dropping of orbits in the daily CMG. |
Problem Statement | Orbits were being dropped during processing. This turned out to be the result of how production rules were implemented. |
Description of Change | Two changes: 1) modified source code so that it would compare the dataday of the inputs against the dataday stored in LUN 10258 of the pcf and process those that related to that dataday and discard those that did not. 2) modified production rules to stage the inputs for the dataday to be processed as well as those for the previous dataday to insure that no orbital products are missed as inputs. |
Products Affected | L3 Land Surface Reflectance CMG (MOD09CMG, MOD09CMA) |
Software Affected | PGE75 |
Processing String to Receive the Change | Terra Reprocessing, Aqua Reprocessing |
Downstream Product Effects | None. |
Data Granules to be Used for Science Testing | 2000-175 - 2000-177, full data days, to insure orbital inputs that cross data day boundaries are processed correctly. |
Justification | This change will prevent holes in the PGE75 outputs by insuring that all potential inputs are staged and processed accordingly. |
Effective Date for Implementation of Change | Data day 2000-160 for C5 Terra Reprocessing. |
Status | PI approved. Sadashiva Devadiga approved for Land, Vincent Salomonsom approved on 10/17/06. |
