Abstract To implement updated code to fix bugs in PGE85 v6.0.5, PGE55 v6.0.3 and PGE81 v6.0.3 and transition to Linux/gfortran.
Problem Statement Clear Sky Radiance codes were updated to fix bugs and transition to Linux/gfortran.
Description of Change PGE85, PGE55, PGE81 together produce a Clear Sky Radiance bias file that is used by the PGE06 cloud top algorithm. These codes were ported to gfortran after conversion of ancillary data files. The CSR algorithm was updated to use MODIS Collection 6 destriping software (MOD_PRDS).
Products Affected MYDCSRFM, MYDCSRQC, MYDCSR_8, MYDCSR_B, MYDCSR_D, MYDCSR_G
Software Affected PGE85 v6.0.5, PGE55 v6.0.3, PGE81 v6.0.3Recipes: 85/55/81[AP]M1M_C6_s1m 6.0.28[AP]M1M_C6_A6m 6.0.3[AP]M1M_C6_A7m 6.0.3
Processing String to Receive the Change Aqua Forward, Aqua Reprocessing
Downstream Product Effects MYD06_L2 (cloud top products)
Data Granules to be Used for Science Testing A series of science tests were performed to develop the new algorithm.2010-059
Justification Provides better clear sky radiance estimates for use by PGE06. Allows use of gfortran processing.
Effective Date for Implementation of Change Jan 1, 2014 for Aqua forward reprocessing. Reprocessing for the full Aqua mission.
Status Major algorithm development and testing completed. Steve Platnick approved on 1/8/2014. Michael King approved on 2/7/2014.
