[Wrf-users] floating point with WPP with Qcloud or Qice

[Daniel van Dijke]

Hi,

 

I'm using WRF-ARW v3 and WPP v3. For our database we need regular lat-lon grib files, that's why I use the WPP. For our cloud fraction algorithm we need the Qcloud and Qice. But when I set 

 

(CLD WTR ON MDL SFCS ) SCAL=( 3.0)

 L=(00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000)

 (CLD ICE ON MDL SFCS ) SCAL=( 3.0)

 L=(00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000)

 

To:

 

(CLD WTR ON MDL SFCS ) SCAL=( 3.0)

 L=(11111 11111 11111 11111 11111 00000 00000 00000 00000 00000 00000 00000 00000 00000)

 (CLD ICE ON MDL SFCS ) SCAL=( 3.0)

 L=(11111 11111 11111 11111 11111 00000 00000 00000 00000 00000 00000 00000 00000 00000)

 

It gives a floating point acceptation. 

 

In GRIBBIT.f it calls the function W3FI72, this is the one to give the error. 

The error occurs when the variable "GRIDO" is to short. Because for each level it should be dx * dy, but in the case of the floating point acception it is about 12 to short.

I really don't have a clue why this is, because the same output give nice output with ARWpost->GrADS.

 

Do you know what is going on and where to look for the solution?

 

Thanks in advanced!

PS When I try to walk around the problem by creating an extra gribfile with only Qcloud and Qice I get other problems, see email I just sent a few minutes ago.
