Time interval between measurement start points.


<time intverval>



Comment: The interval between consecutive measurement start points is stated in the same units as the file time axis, (fractional) days. For hourly averaged data, it is 1/24 = 0.041667, for 3-hourly data 0.125, and for daily averaged data, it is 1. Stating this interval implies that it applies for the whole data section of the file. Shifts in time need to be corrected, holes in the time series need to be filled with missing data tags, and the data needs to be aggregated to averages as required by the observation type. Please use a precision of at least 6 digits right of the decimal point.
