[ncl-talk] trouble with 3A12 dataset

[Geeta Geeta]

Hi all. 
I have to plot the TRMM 3A12 data which is gridded. I am getting following error even after defining the units of the cordinate variables.
Variable: surf_pptnType: floatTotal Size: 460800 bytes            115200 valuesNumber of Dimensions: 2Dimensions and sizes: [longitude | 720] x [latitude | 160]Coordinates:             longitude: [-180..180]            latitude: [-40..40]Number Of Attributes: 5  longitude : degrees_east  latitude : degrees_north  _FillValue : -9999.9  units : mm/hr  hdf_name : surfacePrecipitation(0)  (0) min=0   max=2.99362(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' '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 am attaching the figure which is distorted. 
Secondly the documentation says that the range of the data is from  SurfaceRain Float SDS 4 nlat*nlon -­‐  0 – 3000 mm/hr http://pps.gsfc.nasa.gov/Documents/filespec.TRMM.V7.pdf) Page 203. 
when I plot the MinMAx values of this variable, hdf_name : surfacePrecipitation(0)  (0) min=0   max=2.99362
Geeta.
