I guess the 'best' data is the minute(s)-by-minute(s) but if that is not available your next best is hour-by-hour. As Tom said importing with a 1 hour interval will work, but you will need to massage your data. Since you only have hour-by-hour data you have lost the 'resolution' that comes with minute(s)-by-minute(s) data (eg time of max outTemp for the day), the best you will get from the hour-by-hour data you have are the daily max/min/totals, your hi/low times will be at best ballpark (ie within the hour). When you import, wee_import will want single outTemp value for a given time; your data has (for most) the hour hi and hour low values. How you derive that single value to be imported for that hour is up to you, but remember if you want to keep the daily hi/lows that you presently have one of your imported records for the day must have the daily hi and another must have the daily low. The weeWX daily hi and low values will be derived from the values you import. Cumulative obs (rain is the obvious one though you do have windrun as well) are treated differently as the key daily aggregate is the daily total. These should come across OK given your data. One thing you may or may not have considered (and I shudder for mentioning it) is if you have previously posted your data to Weather Underground you may find you have 'better' data there. wee_import can import directly from WU. Is it possible to "fudge" the hourly data to make it look like hourly > readings? Should not be too difficult with python. > Fudged data is better than no data. > Of course you can. As to your last sentence, I think you might find there are two schools of thought on that one :) I think it will be a (relatively) slow process given the massaging you will need to do, though your historical data is not going anywhere. I would be very carefully scrutinising the data that is imported to make sure it is what you want.
