More than 90 per cent of the rain falling on the continent of Australia is dissipated by evaporation. Consequently, accurate measurement of evaporation at many stations is essential to making the best use of our limited water resources. Attention is drawn to the unsatisfactory conditions relative to the measurement of evaporation; various types of evaporation pans are described and their advantage s and disadvantages discussed; and suggestions are made for improving the existing network of evaporation stations.
