Sunshine Recorder
notes: label: Description
content: Sunshine recorders determine the number of hours the sun is visible each day, and the time of that visibility. A differential recorder operates on the principle of the differential heating between a blackened bulb and a clear bulb of a differential thermometer. The form was suggested by Delos Taft Maring of the U.S. Weather Bureau and improved by Charles F. Marvin, also of the Weather Bureau.
