Hi Mark:
COARDS does not support 2D lat/lon coordinates. You will need to use CF:
1. change "Conventions" to "CF-1.0"
2. lat/lon coordinates need units of "degrees_north", "degrees_east", not
"degrees"
3. data variables need an attribute "coordinates" with value "latitcrs
longicrs"
the equivilent NcML:
<?xml version="1.0" encoding="UTF-8"?>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"
location="C:/data/2005052500_012-mss.nc">
<attribute name="Conventions" type="String" value="CF-1.0" />
<variable name="latitcrs">
<attribute name="units" type="String" value="degrees_north" />
</variable>
<variable name="longicrs" >
<attribute name="units" type="String" value="degrees_east" />
</variable>
<variable name="t" >
<attribute name="coordinates" type="String" value="latitcrs longicrs" />
</variable>
</netcdf>
