Abstract PGE06 v6.1.4:

Updated MOD_PR04DB code.

Problem Statement PGE06 v6.1.3 has a small bug impacting retrievals for single scan lines.

The small bug in Cloud Optical Properties code was causing an occasional missing scan line in Cloud Optical Property SDS’s at the beginning of a granule (the first scan line of a granule) under certain conditions, for example, where dust cuts across the boundary of two sequential granules.

Description of Change Logic was corrected to avoid failures to process first scan line.
Products Affected MOD_PR04DB
Software Affected PGE06 v6.1.4
Processing String to Receive the Change Terra and Aqua Forward Reprocessing. Terra and Aqua Reprocessing. NRT
Downstream Product Effects None
Data Granules to be Used for Science Testing One day Science for Terra 2017/289 confirmed that the patch was successful
Justification Restored missing retrievals on first scan line of some granules
Effective Date for Implementation of Change Forward Processing: Target date for implementation is 1/1/2018

Re-Processing: No active Terra reprocessing. Use immediately for start of Aqua C6.1 reprocessing

NRT Processing: NRT Target date for implementation is 1/1/2018

Status Major algorithm development completed. Steve Platnick approved 12/18/2017. Michael King approved on 12/18/2017. Gang Ye implemented 01/03/2018.
