Folks,

I have a datasetscan to read GFS Model Data. A variable of a this data is
Temperature_surface. The units for Temperature is Kelvin. I would like of
show this data in degrees celsius. Can I configure this convertion through
of the files catalog.xml or wmsConfig.xml?

My current configurations:

*in catalog.xml:*
  <datasetScan name="gfs" ID="gfs" path="gfs" location="/simepar/gfs">
        <metadata inherited="true">
                <serviceName>simepar</serviceName>
                <authority>simepar.br</authority>
                <dataType>Grid</dataType>
                <dataFormat>GRIB</dataFormat>

                </publisher>
        </metadata>
        <filter>
                <include wildcard="fh.*_tl.press_gr.0p5deg"/>
        </filter>
        <sort>
                <lexigraphicByName increasing="true"/>
        </sort>
        <addDatasetSize/>
        <!--netcdf xmlns="
http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
                <variable name="Temperature_surface">
                        <attribute name="units" type="String"
value="degreesC" />
                </variable>
        </netcdf-->
  </datasetScan>

*and in wmsConfig.xml:*

       <datasetPath pathSpec="gfs/??/*.0p5deg">
            <pathDefaults>
                <allowFeatureInfo>false</allowFeatureInfo>
                <defaultPaletteName>rainbow</defaultPaletteName>
                <defaultNumColorBands>254</defaultNumColorBands>
            </pathDefaults>

            <variables>
                <variable id="Temperature_surface">
                    <defaultColorScaleRange>10 35</defaultColorScaleRange>
                    <defaultNumColorBands>254</defaultNumColorBands>
                </variable>
            </variables>
        </datasetPath>
