Dear NetCDF group,
 
I'm having troubles accessing data from a NetCDF file.  
My aim is to access the data and write to a CSV file in the following format:
 
Latitude  Longitude Date1  Date2  Date 3
 <-- MIN_SFC values -->
 
I have been able to iterate through the MIN_SFC Variable,  I was going to save 
to a dictionary or hash table then realised I don't know which date it belongs 
to or Lat/long and vise versa.
 
Dimensions:
time = 7 // the date field how to convert to a date?
latitude = 292
longitude =341
 
Variables:
float MIN_SFC (time=7, latitude = 292, longitude = 341)
 
I've looked through the online resources, please post a comment or link.  I 
found the ReadNetCDF example useful however it was for version 1.0 and had 
quite a few deprecated methods.
Thanks!
 
<code>
List<Variable> variableList = ncfile.getVariables();

Array data;
 
                for(int j = 0; j < variableList.size(); j++){                   
Variable r = variableList.get(j);

                        System.out.println(r.getFullName());

                        System.out.println(r.getDatasetLocation());

                        System.out.println(r.getNameAndDimensions());

                        System.out.println(r.getDataType());

                    System.out.println(r.getElementSize());                     
System.out.println("-------------") 
                        data = r.read(); int[] shape = data.getShape(); 
                        Index index = data.getIndex();

                          for (int u=0; u<shape[0]; u++) {

                            for (int x=0; x<shape[1]; x++) {

                              double dval = data.getDouble(index.set(u,x));

}}}
