If you manually create a map, you can tell DA using the Time Selection 'MANUAL' option to use only a certain time window for selecting your observations. Can you do this in a script?
I ingest multiple hourly metar files (ie. 17z.sao, 18z.sao, and 19z.sao), but I need to have DA (in a script) plot only the 18z observations? (assuming your command is ingest *.sao The problem I'm having is that 18z observations are sometimes stored in the 19z or even 20z files. My alternative is to write a program that sorts them back into their appropriate files or have DA selectively use only the XXz observations. Using the Time Selection is great if I'm creating them manually but I need to use scripts.
Any thoughts would be appreciated.
