A pyranometer (from Greek πῦρ (pyr) 'fire' and ἄνω (ano) 'above, sky') 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/m 2) from the hemisphere above within a wavelength range 0.3 μm to 3 μm.
A pyrheliometer is an instrument that can measure direct beam solar irradiance. [1] Sunlight enters the instrument through a window and is directed onto a thermopile which converts heat to an electrical signal that can be recorded. The signal voltage is converted via a formula to measure watts per square metre.

A pyranometer is a type of actinometer used to measure broadband solar irradiance on a planar surface and is a sensor that is designed to measure the solar radiation flux density (in watts per metre square) from a field of view of 180 degrees.
The upfacing pyranometer measures the incoming global solar radiation. The downward facing pyranometer measures the reflected global solar radiation. The ratio of the reflected to the global radiation is the solar albedo and depends on the properties of the surface and the directional distribution of the incoming solar radiation.
An optical pyrometer A sailor checking the temperature of a ventilation system. A pyrometer, or radiation thermometer, is a type of remote sensing thermometer used to measure the temperature of distant objects.
Additionally, the model provides the spectrally-integrated (or "broadband") irradiance values, which can then be compared to measurements from a pyrheliometer (for direct radiation) or pyranometer (for diffuse or global radiation) at any instant.
