Abstract PGE128 v6.0.8. Removed the constraint that PGE128 run only after July 9, 2003. The PGE can now run for any day of the mission.
Problem Statement C6 reprocessing required correcting the L1B from the early period of the mission (2000055 - 2003192) for polarization.
Description of Change Update the production rule to run the PGE for any day of the Terra and Aqua mission.
Products Affected MxD02*, MxD09*, MxD13*, MxD15*, MxD17* and MCD43*
Software Affected PGE128 v6.0.8
Processing String to Receive the Change Terra Reprocessing and Aqua Reprocessing
Downstream Product Effects None.
Data Granules to be Used for Science Testing Process one global day on the MODAPS test system and use initial 16-day period from the C6 operational processing as test data. 2010-059
Justification Use of polarization corrected L1B data as input to surface reflectance from day 2003193 and onwards introduced a temporal inconsistency in the time series of surface reflectance product. Downstream products using the surface reflectance as input is expected exhibit similar trending in the product time series.Need polarization corrected L1B from the period 2000055 - 2003192, to facilitate reprocessing of surface reflectance and downstream (VI, LAI-FPAR, GPP) from the period.
Effective Date for Implementation of Change Completed.
Status Major algorithm development completed. Sadashiva Devadiga approved on 05/15/2015. Michael King approved on 05/26/2015.
