### what is equivalent of IOPTM (coherens1) in coherens2?

I don't have this option (IOPTM) in coherens2.

IOPTM
Determines the type of meteorological forcing.
0 : Surface stress, heat fluxes, salinity fluxes and solar radiation are zero.
1 : Surface stress is constant in space and time. Heat fluxes, salinity fluxes
2 : Surface stress, heat fluxes, salinity fluxes and solar radiation are uniform
in space but non-uniform in time. They are calculated as a function of
the meteorological forcing data using the formulations provided in the
program. For the salinity flux either Evap − Rpr (IOPTSA = 1) or Rpr
(IOPTSA = 2) is supplied by the user.
3 : Surface stress, heat fluxes, salinity fluxes and solar radiation are non-
uniform in space and time. They are calculated as a function of the
meteorological forcing data using the formulations provided in the pro-
gram. For the salinity flux either Evap − Rpr (IOPTSA = 1) or Rpr
(IOPTSA = 2) is supplied by the user.
4 : Surface stress, heat fluxes, salinity fluxes and solar radiation are uniform
in space but non-uniform in time. Surface stress is evaluated using equa-
tion (3.1.168). Non-solar and solar heat fluxes and the evaporation minus
precipitation rate are supplied by the user.
5 : Surface stress, heat fluxes, salinity fluxes and solar radiation are non-
uniform in space and time. Surface stress is evaluated using equa-
tion (3.1.168). Non-solar and solar heat fluxes and the evaporation minus
precipitation rate are supplied by the user.
Default value is 0.

how can I set meteo input data uniform in space but non-uniform in time?
thnx,

Hi Sou, there is not a real alternative in V2, each proces has to be processed individually, hope this helps
