Abstract

The UK Climate Projections 2009 (UKCP09) dataset contains future climate projections for the UK and a measure of uncertainty for these values. Understanding both types of data is important for scientific interpretation, but just presenting information visually has limitations because of the amount of data involved. This study evaluates the use of sound to represent uncertainty using a survey tool developed with Google Maps API (Application Programming Interface) (n = 72). Use of sound to reinforce visual information results in significantly better performance for participants (p = 0.006), and participants also performed more effectively with pre-existing knowledge of the dataset and with practice.
