 ===================
 Using 3 dimensional labeled arrays (`Xarray`) we are able to run calculations using meteorological data across many points at once. This process has been parallelized using `dask` and `xarray`. Both of these packages can be run locally or on cloud HPC environments.

+=======================
+
+Enhancements
+------------
+Diffusion
+
+- Created a 1D diffsion tool. ``Tools - Edge Seal Oxygen Ingress.ipynb``
+- Created a diffusion module. Only has a 1D diffusion calculation function (``pvdeg.diffusion.esdiffusion``)
+but 2D calculation combing soon.
