<DIV><FONT size=2 face=Arial>I have a NetCDF file which I can ingest and display
in GrADS with out a problem. The LON parameter is set to a 0-360 grid as
opposed to 0-180W & 0-180E (or 0 to 180 for east and 0 to -180 for
west). If I "set lon 239 244" and then display my variable of interest (in
this case U), the data display properly showing the data between 116W-121W (116W
equaling -116=244-360 and 121W equaling -121=360-239). That all is fine
until I try to save my geographically subsetted area to a new .nc file using the
sdfwrite function. The file saves fine, but it saves the LON information
in the 0-360 format instead of the 0 to -180 format which I need for another
application. Is there a way to either 1) save the new, subsetted .nc file
with the lons converting to the in 0 to -180 format as part of the
process or 2) convert the lon format within GrADS first and then save the
new .nc file with the lon values in the format I want? Can I subtract 360
from my "lon" variable to create a 'new' lon variable?</FONT></DIV>
