Sonja,

Can you upload your data here and let us know when it is uploaded?

> Hello,
> 
> I am trying to collaborate with a colleague who uses IDV to visualize her 
> modeling results.  I have my own data that I would like to overlay on hers 
> using IDV.  I use IDL, and I am trying to export my data into netCDF format.  
> I know how to do this, but I don't know what IDV is expecting of me.  Let me 
> describe my data:
> 
> At simplest I have three arrays: time, latitude and longitude.
> 
> time[i] = time of event
> latitude[i] = latitude of event
> longitude[i] = longitude of event
> 
> I wrote a program in IDL to make a netcdf file of three variables: time, 
> latitude, and longitude.  I know I did this correctly because I reread the 
> file back in to IDL and was able to extract my arrays.
> 
> But, IDV doesn't know what to do with my data.  It complains that I don't 
> have any "gridded" data in my file.  So, I took my data in IDL and made a 
> 200x200 element array of the density of my events with respect to lat and 
> lon.  So each element of the array is a pixel on a map, and the value 
> represents how many events were in that pixel. I saved that 200x200 array in 
> a netcdf file, but alas, IDV doesn't get it.
> 
> So, I realize I don't know what IDV is expecting here with my data, but I 
> would like to format my data so that it understands it and I could use IDV to 
> plot it on a map.
