Evaluate climate change using ArcGIS API for Python and ArcGIS Maps SDK for JavaScript

Description

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

Each chapter is described below:

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

2. The second section, explain how to analyze trends/patterns in multidimensional data. Also, calculate results using the following tools: Generate Multidimensional Anomaly, Generate Trend Raster and Predict Using Trend Raster.

3. The third section, shows how to create animations and timelines of climate data using the 19 Bioclimate Projections of WorldClim using ArcGIS Maps SDK for JavaScript.

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

CCMa-CanESM2 Model The second generation Canadian Earth System Model (CanESM2) (CanESM2) is the fourth generation coupled global climate model developed by the Canadian Centre for Climate Modelling and Analysis (CCCma) of Environment and Climate Change Canada. CanESM2 represents the Canadian contribution to the IPCC Fifth Assessment Report (AR5).

MOHC-HadGEM2-ES Model

The HadGEM2 family includes a coupled atmosphere-ocean configuration, with or without a vertical extension in the atmosphere to include a well-resolved stratosphere, and an Earth-System configuration which includes dynamic vegetation, ocean biology and atmospheric chemistry.
