Standard CEF 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 :doc:`time range <time_period_codes>`.
minimum The data values are the minimum value of the variable over the :doc:`time range <time_period_codes>`.
mean The data values are the mean of the variable over the :doc:`time range <time_period_codes>`.
median The data values are the median of the variable over the :doc:`time range <time_period_codes>`.
mid_range The data values are the mean of the maximum and the minimum of the variable over the :doc:`time range <time_period_codes>`.
mode The data values are the mode (most common value) of the variable over the :doc:`time range <time_period_codes>`.
sum The data values are the sum of the variable over the :doc:`time range <time_period_codes>`.
variance The data values are the variance of the variable over the :doc:`time range <time_period_codes>`.
standard_deviation The data values are the standard deviation of the variable over the :doc:`time range <time_period_codes>`.
