How does a sunshine recorder work?

Solar radiation is measured periodically throughout the day. The most precise measurements are taken by satellites outside the Earth's atmosphere. Solar radiation is measured in nanometers (nm) from peak to peak. The shorter the wavelength, the more energy it has. Solar radiation is measured using a variety of tools, including: Pyranometers: Measure global radiation Pyrheliometers: Measure direct radiation Solarimeters: Measure the intensity of solar radiation Sunshine recorders: A less accurate, but less expensive alternative to other methods Filter radiometers: Measure the spectral...

Solar radiation is measured periodically throughout the day. The most precise measurements are taken by satellites outside the Earth's atmosphere. Solar radiation is measured in nanometers (nm) from peak to peak. The shorter the wavelength, the more energy it has.

Solar radiation is measured using a variety of tools, including:
Pyranometers: Measure global radiation
Pyrheliometers: Measure direct radiation
Solarimeters: Measure the intensity of solar radiation
Sunshine recorders: A less accurate, but less expensive alternative to other methods
Filter radiometers: Measure the spectral distribution of irradiance and aerosol contents in the atmosphere
