[gradsusr] How to plot *.hdf file

[Huddleston, John]

Quamrul

I see from http://en.wikipedia.org/wiki/Equirectangular_projection that plate carree is a rectangular grid.

Using the information from your file I took an estimate of a control file to read the hdf file. See attached image.

dset GVIX_NN_G16_C07_NVI_Y2011_P15.hdf
dtype hdfsds
title NVI_2011_15
undef -999
options yrev
xdef 2500 linear -179.072 0.144
ydef 904 linear -55.072 0.144
zdef 1 levels 1000.0
tdef 1  linear 00:00Z15jan2011 1dy
vars 1
NVI_2011_15=>nvi 1 y,x NVI_2011_15
endvars

if you are using grads 1.9 versions then there would be one executable gradshdf/gradsnc give the comman sdfopen <the entire path to the file> and enter.if you are working 0n 2.0 versions then there is no seperate executable i guess.try it u will get

in that case ,if there are sone missing values and i do aave of a particular region ,what i found that the missing values do not participate in the averaging ,is it really so??

I could be wrong, but I don't think you can do resampling to fill in missing values in Grads.

how to interpolate for the missing values in grads.I have a file(ch-a..in nc format) of which I have to average the values for a particular region ,but since for different periods different values are missing so averaging would not be proper.any way is there to assign the average of the available values to the missing values, sort of resampling??
