📰 Custom Issue

Hi everyone, we are currently working on a feature to make our multimodel calculations lazy in ESMValTool by depending on iris.analysis to perform the calculations (ESMValGroup/ESMValCore#968). The documentation states that MEAN, STD_DEV and VARIANCE already have lazy implementations via dask.

Looking through the code, I have noticed that iris.analysis.MIN and iris.analysis.MAX also have lazy functions associated with them, but these are not mentioned in the documentation as being lazy. I'm wondering if I'm missing something or if this information is not yet available in the documentation.

We would be very interested to also make some of the other statistics lazy on our side, i.e. MEDIAN and PERCENTILE, which also have implementations available via dask.
