Physique Standard

Namelist from Aurore Voldoire. (2007-06-04)

+ modifiedaccofgy:
<   ZRI(JLON,KLEV)=ZRICRIT
---
>   ZRI(JLON,KLEV)=ICM(JLON,KLEV)*(ZRICRIT-ZEPS1)&
>    &+ (1-ICM(JLON,KLEV))* ZRICRIT

+ original routine achmt (old coefficients)

Ocean:
Nemo + Lim
Monoprocessor mode
Physics: standard forced configuration with double mixing
New lateral accretion (0.3->1m)
New runoff for Gange, Lena, Mississipi, Amazonia, Zambezi and Nile
Sea albedo reset to .065 instead of .07
Calving melting heat bugfix
Great Lake: wrong interpolation weights corrected
Baltic: new interpolation tested
Ice albedo reset to mean clear-overcast sky values (0.83)
new Gurvan TKE

Climatological runoffs (TRIP disabled)

Coupler:
Oasis V3
22 (7+15) coupling fields (oceanic currents and ice velocity added)
Non solar subgridding, no flux correction
dQ/dT between -10,-5
Non solar flux re-gridding calculated with oceanic day-1 surface temperature instead of day-2 values
Corrected Gibbs orography effect on atmospheric gridded surface temperature
