I am seeking an advice on how to read CMORPH precipitation daily data and generate howmoller graphics. The detail specification is a high resolution 8km precipitation data at daily temporal scale. It's possible to use GrAds?
It seems like there are at least three issues here.
First, there are tons of ways to "read" the CMORPH data. To obtain the data, I assume you have visited http://www.cpc.ncep.noaa.gov/products/janowiak/cmorph_description.html
The files can be downloaded directly from there (and/or via ftp).
Those files are in binary format, and there is FORTRAN code provided to be able to read the files. (Which you could translate to whatever language you use.)
Second, you specified that you are interested in the 8km data, which has 30-minute temporal frequency. You should think about whether that is the product you really want to use for your purposes. There is also a 0.25-degree 3-hourly product that might be somewhat easier to use. If you decide to use that product, and you know how to use netCDF files, then you can also get the data already converted to netCDF from NCAR: http://rda.ucar.edu/datasets/ds502.1/#!access
Third, you said you want to make Hovmueller plots, and ask if GrAds can be used. Yes, definitely if you know GrAds, then you can use it. Any of the common analysis languages can be used: NCL, Python/Matplotlib/PyNGL, Matlab, IDL, etc.
Here's examples with NCL: http://www.ncl.ucar.edu/Applications/time_lon.shtml
