Question

Solar radiation flux is usually measured with the help of a

Answer 1

A pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface and it is designed to measure the solar radiation flux  density (W/m2) from the hemisphere above within a wavelength range 0.3 μm to 3 μm.

Answer 2

Answer:

Pyranometer is used to measure the solar radiation flux.  The word pyranometer is originated from Greek, thus 'pry' means fire and 'Ano' means above the sky.

Explanation:

There are other few devices to measure the solar radiation like pyrheliometer and photoelectric sunshine recorder

SOLAR RADIATION:

                 The energy flux emitted by the sun is called solar wind and it is intercepted by the outermost protecting layer of earth's surface it is called solar radiation.

PYRANOMETER is used to measure the total hemisphere radiation on horizontal surface. The unit to measure the solar radiation flux is  $W/m^{2}$ .
