[IDV #NYY-367135]: updates - netCDF / CF / IDV

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>
