Pyrheliometer
notes: label: Description
content: A pyrheliometer measures direct solar radiation. This silver disc pyrheliometer was designed by Charles Greeley Abbott and probably built in the shops of the Smithsonian Astrophysical Observatory. It uses a blackened silver-disc reflector with a shutter to create temperature fluctuations that are proportional to the intensity of the solar radiation incident upon it.
