Evaluate climate change projections using GIS

Description

Evaluation of the Climate Change Models (GCM) CCCma-CanESM2, MOHC-HadGEM2-ES and MIROC-MIROC5, using Arcgis for Python.

Each section is described below:

1. The first section shows how to Geoprocess NetCDF files and convert them to CRF (Cloud Raster Format).

2. The second section evidences how to analyze trends and patterns in multidimensional data.

3. The third section shows how to create animations and timelines of climate data.

4. The fourth and final section shows how to convert and export multidimensional data to tables and shapefile formats.
