converting kelvin to celsius coupling.dat file

[turuncu]

Hi,

In coupling.dat file, to convert Kelvin to Celsius the offset value is defined as 273.16d0 for Tair variable

Code: Select all

'Tair'                                             ! at 2 m, usually
  'Tair'
  'surface air temperature'
  'Celsius'                                        ! [Kelvin]
  'r2dvar'
  273.16d0                                         ! Kelvin to Celsius
  1.0d0

but i think that it must be -273.16d0. Am i correct? Because the atmospheric model sends Kelvin in my case. Also, i think it is not necessary to define scale or/and offset when radiation flux variables are in W/m2. I just want to be sure.

Thanks
