Hi:
I am trying to plot few variable from a GRIB data file whose specifications
are
-------------------------------------------------------------
VALUE GRID DESCRIPTIONS
96 Arakawa staggered E-grid on rotated latitude/longitude grid (used by the 12 km Eta model)
Ni 606
Nj 1067
La1 3.441S
Lo1 211.201E = 148.799W
Res. & Comp. Flag 1 0 0 0 1 0 0 0
La2 50.000N
Lo2 249.000E = 111.000W
Di 88 millidegrees (=53/605 deg)
Dj 75 millidegrees (=40/533 deg)
Scanning Mode 01000000
------------------------------------------------------------
The lat/ lon variable, their max/min and the error messg when I run the
ncl is as follows:
---------------------------------------------------------------
float gridlat_96 ( gridx_96, gridy_96 )
corners : <ARRAY>
GridType : Arakawa staggered E-grid on rotated latitude/longitude grid-point array (velocity points)
units : degrees_north
Dj : 0.075
Di : 0.088
LoC : -111
LaC : 50
Lo1 : -148.799
La1 : -3.441
float gridlon_96 ( gridx_96, gridy_96 )
corners : <ARRAY>
GridType : Arakawa staggered E-grid on rotated latitude/longitude grid-point array (velocity points)
units : degrees_east
Dj : 0.075
Di : 0.088
LoC : -111
LaC : 50
Lo1 : -148.799
La1 : -3.441
(0) Min/Max: -3.48216 90
(0) Min/Max: 0 356.802
(0) check_for_y_lat_coord: Warning: Data either does not contain a valid latitude
coordinate array or doesn't contain 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' 'degreeN' 'degreesN'
(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'
---------------------------------------------------------------
thanks,
Mukul
