Yes, i know its a Grads file ..! i have attached the control file and the grid file can be downloaded frm the link given below! http://www.4shared.com/file/cuSG-05j/rf05_1975.html I have not used Grads before, still i was able to read in the control file and get the basic info.! but, i am not sure about the package required for .grd files in R - will i be able to read a Grads grid file into R???
I am afraid there is no direct solution at this time in R. Perhaps the following script can help converting the data? http://cookbooks.opengrads.org/index.php?title=Recipe-002:_Saving_GrADS_variable_data_to_a_text_file Hope this helps, Rainer
