Jeff,
<div>You can use ‘time’ for the <SDF_dimension_name> in your edef statement — it won’t really matter what name you use as long as the name matches one of the dimensions in the file and you provide all the remaining needed metadata for the ensemble axis: <size>
names <list of names>.</div>

<div>Since the data files were created using the NCDC Weather Radar and Climate Toolkit, I'm using xdfopen to display the data. If I remove one of the dimensions (i.e., either time or radar site), then I can display a maximum (either across multiple sites at
one time or across multiple times at one site) by using the time dimension as a dummy dimension. However, I see from the xdfopen documentation that the syntax above for EDEF isn't acceptable as it is for full blown data that you'd need a complete control file
for. However, the data files themselves do not have an ensemble dimension, and therefore I don't know how to follow the indicated convention for the EDEF line:<br>
<br>
<code>edef <<i>SDF_dimension_name</i>> <br>
edef <<i>SDF_dimension_name</i>> <<em>size</em>><br>
edef <<i>SDF_dimension_name</i>> <<em>size</em>> names <<em>list of names</em>> <br>
