xgcm is a python package for analyzing general circulation model (GCM) output data. xgcm is built on top of xray.
xgcm is motivated by the fac that our models are getting bigger and bigger, and we are in desperate need of some scalable analysis tools.
The main functionality xgcm adds on top of xrayy is an more complex representation of the [grids](see https://en.wikipedia.org/wiki/Arakawa_grids) commonly used in numerical modeling and an implementation of differential and integral operators (e.g. gradients) in the specific ways appropriate to these grids.
