TYPE: bug fix

KEYWORDS: RRTMG-K option (sw and lw option 14)

SOURCE: Soonyoung Roh and Hwan-Jin Song (National Institute of Meteorological Science, Korea)

DESCRIPTION OF CHANGES:
The bugs include wrong surface downward diagnostic output for long- and short-wave fluxes (clear sky fluxes misplaced in cloudy sky flux arrays), a wrong data statement value for wavenum2 and a wrong value used for bound check for effective size of snow.
Affects radiation driver call arguments for lw and sw scheme and internal numerical values in two places of the shortwave scheme (rrtmg_swk).

This has been confirmed as a correct fix by the developers.

ISSUE:
Fixes #1312

LIST OF MODIFIED FILES:
M phys/module_ra_rrtmg_swk.F
M phys/module_radiation_driver.F

TESTS CONDUCTED:

  1. Test reported by source (documented in Issue RRTMK bugs reported #1312)
  2. Jenkins testing all pass

RELEASE NOTE:
Fixed a bug in surface downward diagnostic output of long- and short-wave fluxes and two other bugs involving wrong numerical values used in the code (Thanks to Roh and Song of NIMS, Korea).

@dudhia
Jimy,
This change seems very narrowly focused.
