[RegCNET] Incorrect nc data produced with interpolation of CRU data

[Tolga Ozdemirel]

Dear All,

Our purpose is to produce continuous climate variable surfaces using CRU 
data and use this surfaces in ArcGIS software.

We produce DOMAIN.CTL without any errors after preprocessing and we can 
see graphs in GrADS normally. Then we interpolate CRU observational data 
(without any errors) to our RegCM grid which was produced by 
preprocessing step. Now we have .nc files and we produced .cdl files 
either (to check data manually). We converted that .nc files with ArcGIS 
and we noticed that data could not correct (for example for 
temperature), because the range of the temperature data was (-98C) - 
(+98C) in a small region that we defined in domain.param and cru.param 
files. We checked .cdl file for temperature and our .cdl file contains:


netcdf TMP_65-99 {

dimensions:

lon = 49 ;

lat = 32 ;

time = UNLIMITED ; // (420 currently)

variables:

float lon(lon) ;

lon:long_name = "Longitude" ;

lon:units = "degrees_east" ;

lon:actual_range = 13.56736f, 48.08979f ;

float lat(lat) ;

lat:long_name = "Latitude" ;

lat:units = "degrees_north" ;

lat:actual_range = 32.12214f, 49.31968f ;

double time(time) ;

time:long_name = "Time" ;

time:units = "hours since 1900-1-1 00:00:0.0" ;

time:actual_range = 570120., 876168. ;

short TMP(time, lat, lon) ;

TMP:long_name = "" ;

TMP:units = "degC" ;

TMP:missing_value = -32767s ;

TMP:add_offset = 0.f ;

TMP:scale_factor = 0.003051804f ;

We are not sure where the problem is and any help would be appreciated. 
Thanks in advance.
