nctoolkit.DataSet.tmean

DataSet.tmean(self, over='time')

Calculate the temporal mean of all variables

Parameters

over (str or list) – Time periods to average over. Options are ‘year’, ‘month’, ‘day’.

Examples

If you want to calculate mean over all time steps. Do the following:

>>> ds.tmean()

If you want to calculate the mean for each year in a dataset, do this:

>>> ds.tmean("year")

If you want to calculate the mean for each month in a dataset, do this:

>>> ds.tmean("month")

If you want to calculate the mean for each month in each year in a dataset, do this:

>>> ds.tmean(["year", "month"])

This method will also let you easily calculate climatologies. So, if you wanted to calculate a monthly climatological mean, you would do this:

>>> ds.tmean( "month")

A daily climatological mean would be the following:

>>> ds.tmean( "day")
