Step-by-Step Instructions

Part 1 Download Software and Data

Install ArcGIS software and download data from NCAR Climate Change Portal.

Part 2 Calculate Summer Air Temperature Averages 1980-1999

Calculate summer average temperatures during the growing season (June, July, and August) using simulated, present day climate modeled output (1980 to 1999).

Part 3 Calculate Summer Air Temperature Averages 2021-2040

Calculate summer average temperatures during the growing season (June, July, and August) using projected, future climate modeled output (2021 to 2040).

Part 4 Compare Average JJA Temperatures for both Model Runs

Visually compare the temperature differences for the (1980 to 1999) and the (2021 to 2040) model runs.

Part 5 Create a Temperature Anomaly Map

Create a temperature anomaly map to highlight areas around the globe that will experience either air temperature increases or decreases in 2030 relative to 1990.
