Re: THREDDS Catalog Validator

Hi Hongjun,
    I might add that I did that modification for you in the xml file that
is posted on dataportal, you should be able to retrieve it by
pointing your IE browser to http://dataportal.ucar.edu/xml/ucar/cgd/cas.ctx
or using netscape and doing "view source".
thanks, Luca
