Given that monthly log files are used as input for '''updating the all-time, all-monthly (from version 1.9.3), and this year record extremes''', for '''creating missing dayfile.txt entries''', and for '''creating NOAA style reports''', you may have some information from your weather station for a period before you first starting using Cumulus that you want to include.
There are some postings in the
Essentially match the fields listed in [[Monthly_log_files#List_of_fields_in_the_file|Monthly log files: List of fields in the file]] below with the fields you have available in your source.
'''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 (integer) 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 weather station outputs. See, for example ''EasyWeather'' differences in [[FAQ#What_do_the_various_wind_speeds_in_Cumulus_correspond_to.2C_with_Fine_Offset_stations.3F|FAQ: What do the various wind speeds in Cumulus correspond to with Fine Offset stations]] and other answers in the FAQ to pursue this; or
'''The date that Cumulus first started tracking all-time records''' (<#recordsbegandate> see [[Webtags#Records]]), does ''not'' need to be updated for Cumulus to recognise earlier monthly log files in its ''data'' subfolder and in the various display options available from the Cumulus main screen. If you use the '''Edit''' functions to update the stored extremes as described above, any monthly logs found will be used, not just those after the initial Cumulus start date recorded in cumulus.ini, so the date will no longer reflect the start of analysis for all-time records. If you do choose to edit the start date, the method is to stop Cumulus, and amend the ''StartDate='' line in [[cumulus.ini]] within the main Cumulus folder before re-starting Cumulus, but (in case you make a mistake) back up everything first!
If you leave the start date unchanged note that <#recordsbegandate> is on the default Cumulus ''recordsT.htm'' template with the label "Records began on", and you might want to amend that label wording on that template to indicate it is the date that Cumulus running began, rather than the date the station began operating and producing observations.
