Import historical data from Ambientweather.net into Cumulus

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

Long delay, and I can't be much help. The basic process would be...

Reformat your Ambient data into CMX monthly log file format - probably lots of column swapping, maybe a bit of conversion

Once you have the monthly logs, then set the station start date in CMX to when your Ambient data starts.

Then run the CreateMissing utility to create the dayfile entries from the monthly log files.
