Hello,everyone!

    I have a question about the SIGMAtoP of  the latest regcm3(2006).

    After the simulating by the regcm3,I do SIGMAtoP in  output directory,and copy pdef,xdef,ydef,tdef from ATM.********.ctl file,but while displaying  the PLEV_VAR results in

GrADS,the result is not correct and illogical.I also display the viriable in ATM.********.ctl in GrADS,it seems reasonable,the following  is what I find:

 ga-> open PLEV_VAR.ctl
Scanning description file:  PLEV_VAR.ctl
Data file PLEV_VAR is open as file 1

and I also do the SIGMAtoP for ICBC in Input directory,its results is right.I ever used the regcm3 of 2005and find no problem in SIGMAtoP of output,so I wondered!

Please tell me !

At last,can anyone give me the source of regcm3 in 2005,thank you !

  Hope for you reply!
