Hi Mark,
It looks OK to me and I can get it to open in both ToolsUI and IDV
2.1RC2 (but not 2.0).
One problem is that the PointObs tab in ToolsUI isn't very highly
developed. ToolsUI is more a debugging tool than anything else and for
PointObs it isn't particularly great for that. First off, you have to
hit the far-right icon ("arrow pointing down at box") which is the "get
ALL data" request. Then it will show the points on the map and list them
to the right. However, it displays all the lat, lon, alt, time stuff but
not the observation data. We'll try to make it more useful in our next
pass over the PointObs tab.
What version of the IDV are you using? The data failed to read into IDV
2.0 but it read fine into IDV 2.1RC2. When I pointed the IDV Data
Chooser at the file, I also selected "netCDF Point Data files" from the
"Data Source Type" pull down list. It popped me over to the "Field
Selector" tab and it gave me two "Point Data" options: Plot and List. I
don't know how to drive the IDV Point Data interfaces but I could see
the data when I went with the "Point Data List" option.
Hope this helps. Sorry it isn't a bit more straight forward. Let me know
if you have more questions
Ethan
