As a climate monitor I want both first difference (i.e. month by month or year by year changes) and cumulative ice sheet mass balance series so that I can use the appropriate one for the task. At the moment, I have first difference calculated for most, and cumulative for some. It's easyish to convert between then two.
I added some of the basics needed for this into the readers. There's a keyword argument (first_diff) that can be set to True to get the first difference series, otherwise the cumulative series are returned.
