callcorrk.F90 @ 704

Last change on this file since 704 was 650, checked in by jleconte, 13 years ago

Corrected the temperature used to differentiate sublimation and evaporation in watersat_grad
Minor name changes in watercommon
Better physical parametrization of the effective radius of liquid and icy water cloud particles in callcorrk

(for radfixed=true)

Added consistency check in inifis
Moved 1d water initialization from physiqu to rcm1d

Property svn:executable set to *
