• LP NET 07 measures the net radiation across a surface, from near ultraviolet to
• far infrared.
• The Net radiation is defined as the difference between the radiation that reaches the upper surface and the irradiation on the lower surface of the net radiometer.
• The surface of the upper receiver measures the direct solar radiation plus the diffuse one and the radiation at longer wavelengths emitted from the sky (clouds), while the lower receiving area measures the solar radiation reflected from the ground (albedo) and the radiation length wavelengths emitted from the earth.
• The instrument is designed and constructed to be used outdoors in any weather
• conditions.
