[esp-r] Re: instable with global solar

[Georgios Kokogiannakis]

Hi Holger,

The switch from Direct normal to Global Horizontal works fine as far as I am 
aware. It also exorts ascii files correctly (just tested it).
If you manage to open the ascii file you will see a line similar tp this one:
 1967,52.00,0.00,123   # year, latitude, long diff, global horiz rad flag

the last number (i.e. "123") means that it is using Global horizontal. If it 
is 0 then it uses direct normal.

Regarding the MZELWE Longwave Flux Messages I think you should check your 
relative humidity values. Do not leave to 0% - change them to something like 
50%.

Hope this helps.
Georgios
