<div dir="ltr">I have a set of radar reflectivity netcdf files from multiple NEXRAD sites and over multiple times. I wish to display the maximum reflectivity over a window of time and over all radar sites.

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><br></code></div><div><code><span style="font-family:arial,helvetica,sans-serif">Does anyone have any suggestions?
