There are some issues to consider. For example, wind directions might be reported as cardinal points (north, south etc) and need converting to bearings in degrees (spreadsheet packages provide ''look up'' functionality to do such conversions), and dates and times might need some pre-processing (spreadsheet packages usually have ability to select part of a text string and to cocatenate a number of strings) to convert them to text in the formats mentioned above. Cumulus has various wind speed, temperature, and rainfall related fields, not directly available from for example ''EasyWeather'' outputs. See [[FAQ#What_do_the_various_wind_speeds_in_Cumulus_correspond_to.2C_with_Fine_Offset_stations.3F]] and other answers in the FAQ to pursue this. | There are some issues to consider.

The date that Cumulus first started operating, does ''not'' need to be updated for Cumulus to recognise earlier monthly log files in its ''data'' subfolder. However, the web tag associated with that date is on the default Cumulus ''recordsT.htm'' template, and you might want to amend the associated label wording to indicate it is the date that full Cumulus parameter logging/calculation began, rather than the date the station began operating. | |||
If you do need to edit the start date, you can edit the ''StartDate='' line in cumulus.ini with Cumulus stopped, but back up everything first! | |||
