Ensure that VOCAL Can Accept Version 4 CALIPSO File Format #106

Closed kdottiemo closed 7 years ago

kdottiemo commented 8 years ago

The CALIPSO Science Team is moving towards "Version 4" data files, as they are confident in the results that they are seeing from their beta-mode tests. Currently, VOCAL accepts Version 3 data, which is parsed via the ccplot library. Chip would like VOCAL to be able to support both versions of the data, and we have been talking to Chip and Brian Getzewich on the Science Team about the switchover.

From Brian: "My recommendation is to try and see if you can open V4 files with your current readers and see what issues you have. Some of the parameter names differ, but a majority don’t."

We are currently waiting on access to the Version 4 data, as it is not yet publicly available. We were given credentials to the CALIPSO test server, but this process is not yet completed and may not end up being the ultimate mode by which we get the data. (We would need access to a machine that has mounted the server, and that has not yet happened.) Brian Tisdale of the ASDC is looking into giving us access through OPeNDAP.

In the end, VOCAL should maintain backwards-compatibility with Version 3 data but also accept Version 4 data.

What I'm most interested in is whether the Version 4 data is the same layout. If the parameter names are different we can support V4 no problem, otherwise we need to dive into CCPLOT

@kdottiemo did we conclude that version 4 opens and looks fine?

I don't think that we're 100% sure yet. Will let you know. @jjd5150.
