statistics

Standard SEF statistics

The observation statistic describes how the value reported is calculated from the time-series of variable. The set of recommended values is taken from the CF-NetCDF cell methods table.

Statistic	Description
point	The data values are representative of points in time (instantaneous).
maximum	The data values are the maximum value of the variable over the time range.
minimum	The data values are the minimum value of the variable over the time range.
mean	The data values are the mean of the variable over the time range.
median	The data values are the median of the variable over the time range.
mid_range	The data values are the mean of the maximum and the minimum of the variable over the time range.
mode	The data values are the mode (most common value) of the variable over the time range.
sum	The data values are the sum of the variable over the time range.
variance	The data values are the variance of the variable over the time range.
standard_deviation	The data values are the standard deviation of the variable over the time range.
