The Cotton Region Shelter or otherwise known as the Stevenson Screen-

It forms part of a standard weather station. The screen creates, as near possible, a uniform environment in relation to the air outside. The screen allows temperatures to be compared accurately with those measured in earlier years and at different places. It’s painted white to reflect the sun. The Stevenson Screen holds various weather instruments, including, a thermometer, a hygrometer, a dew cell, a phychrometer, a barometer, and a thermograph.
