Obtain CDAT nightly packages

Nightly (or near nightly) versions of CDAT can be obtained as follow:

conda create -n nightly cdat python=2 -c cdat/label/nightly -c conda-forge -c cdat

This command creates a version named nightly which is used in the next command to activate it. It takes some of the packages from the nightly indicated in -c cdat/label/nightly and some of them from the most recent release of uvcdat indicated in -c cdat cdat

source activate nightly

This commands sets up the environment for execution of python with the uvcdat packages.

Nightlies also come with Python3 as a possibility

conda create -n nightly -c cdat/label/nightly -c conda-forge -c cdat cdat python=3
