Dear All,
I'm trying to analyses the results from RegCM4.1.1 modeling results using
NCL6.0.0.
The NCL script is as follows.
;************************************************
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl"
begin
inposatm = addfile("WAfr_ATM.1990010100.nc","r")
lat2d = inposatm ->xlat(:,:)
lon2d = inposatm ->xlon(:,:)
temp1 = inposatm ->t(0,10,:,:)
; Get dimensions from variable
dimvar = dimsizes(ps1)
jlat = dimvar(0)
ilon = dimvar(1)
; create plot
wks = gsn_open_wks("pdf","WAfr_199001")
res = True
res@mpLimitMode = "Corners" ; choose range of map
res@mpLeftCornerLatF = lat2d(0,0)
res@mpLeftCornerLonF = lon2d(0,0)
res@mpRightCornerLatF = lat2d(jlat-1,ilon-1)
res@mpRightCornerLonF = lon2d(jlat-1,ilon-1)
res@mpProjection = "Mercator" ; choose projection
res@mpCenterLatF = 8.0
res@mpCenterLonF = 0.0
res@mpGridAndLimbOn = True
plot = gsn_csm_contour_map(wks,temp1(:,:),res)
end
;************************************************
It gives me these warnings when running this script.
(0) check_for_y_lat_coord: Warning: Data either does not contain a valid
latitude coordinate array or doesn't contai
n one at all.
(0) A valid latitude coordinate array should have a 'units' attribute
equal to one of the following values:
(0) 'degrees_north' 'degrees-north' 'degree_north' 'degrees north'
'degrees_N' 'Degrees_north' 'degree_N' 'degre
eN' 'degreesN' 'deg north'
(0) check_for_lon_coord: Warning: Data either does not contain a valid
longitude coordinate array or doesn't contain
one at all.
(0) A valid longitude coordinate array should have a 'units' attribute
equal to one of the following values:
(0) 'degrees_east' 'degrees-east' 'degree_east' 'degrees east'
'degrees_E' 'Degrees_east' 'degree_E' 'degreeE' '
degreesE' 'deg east'
I checked the information of the variable temp1.
Variable: temp1
Type: float
Total Size: 84992 bytes
21248 values
Number of Dimensions: 2
Dimensions and sizes: [iy | 128] x [jx | 166]
Coordinates:
iy: [-3175..3175]
jx: [-4125..4125]
Number Of Attributes: 6
time : 8766
standard_name : air_temperature
long_name : Temperature
units : K
coordinates : xlat xlon
grid_mapping : rcm_map
I've tried to change its coordinate attributes, but failed to solve this
problem. Besides, the variable temp1 is straightly from the RegCM4.1.1
output, and has the specific coordinate array. I feel more confused about
this. Why did these warnings come out? Please give me some suggestions.
Thank you very much.
Miao
