Measured radiations

Nature	Ref.	Band	Definition	Comments
Global radiation	CE-180	VM	Downward flux over horizontal plane (Sun + Sky)	-
Direct radiation	CE-340	VM	Normal flux in the sun's direction and field	Use of a pyrheliometer
Diffuse radiation	CE-180	VM	(Global radiation) -( Direct radiation over horizontal plane)	Shadow ring CE 183
Reflected radiation	CE-180	VM	Global radiation reflected by the ground	Reversed pyranometer
Albedo	CE-180	VM	Ratio (Reflected radiation) / (Global radiation)	Two opposite pyranometers
Infrared radiation	CE-160	TL	Downward flux over horizontal plane (or upward flux if the pyrgeometer is reversed)	Use of a pyrgeometer
Total radiation	CE-165	TL	Downward flux over horizontal plane	Use of a pyrradiometer
Net radiation	CE-166	VL	(Total radiation)- (upward flux)	Use of a differential pyrradiometer or balancemeter

Bands definition (radiation type) :
