'''Important Rules'''
*Each line must contain the fields in correct sequence (since new versions/builds can add to number of fields, Cumulus will accept lines of various lengths without the more recent fields at the end).
* The date format uses two digits for the year and should be treated as text.
* Times in these files are in the form ''hh:mm'' using the 24 hour clock and local time (system time). See [[FAQ#How_does_Cumulus_handle_Daylight_Saving_Time.3F]].
*See [[#List_of_fields_in_the_file]] to identify if the value you enter for a particular field is an integer (like bearings and humidity values) or a real number (like pressure and rainfall values) in format x.y using your system decimal notation for the decimal point. Fields that accept real number format will also accept integers, but fields expecting integers will not accept decimal points.
*Negative values are allowed for temperatures, all others must be zero or positive. Humidity has a maximum of 99, bearing has a maximum of 360.
*Nulls (',,' if your field separator is a comma, ';;' if your field separator is a semicolon) are not allowed in the row, so if you do not know the value for a particular field within the row, then type in a zero, -999, or -999.9 (check the format in the middle column of [[#List_of_fields_in_the_file]] and think about the range of numbers allowed for particular fields as per examples in previous bullet).
