Weather, Climate, and Evaporative Cooling
The weather (temperature and humidity) has a significant impact on the performance of evaporative cooling technologies.
Below are several websites that can be used to find local weather information for many places throughout the world. This weather information can be input into the Evaporative Cooling Decision Making Tool created by D-Lab to determine the suitability of evaporative cooling technologies.
