Abstract: Disclosed is a heat flux sensor including a body with four or more sensor pairs, each pair including one radiation absorbing, absorptive, sensor for measuring a combined radiative and convective heat flux and one radiation reflecting, reflective, sensor for substantially measuring a convective heat flux, a heating member that is in heat conducing contact with the body, and a temperature sensor thermally coupled with the body for measuring the body temperature Tsen.

Abstract: The invention shows a sensor for measuring diffuse solar irradiance including: an hemisphere having an approximately 2π steradian solid opening angle with a non-transparent layer and a transparent aperture pattern, the transparent aperture pattern providing a near-uniform transmission of the diffuse radiation as seen from near a center of the hemisphere, an aperture being an area occupying a part of the hemisphere surface area that is smaller than 2% and two or more light-sensitive sensors arranged in an array near the center of the hemisphere such that under any position of the sun relative to the sensor at least one of the two or more light-sensitive sensors is shaded from direct solar radiation by the hemisphere with aperture pattern.

Abstract: Disclosed is a pyranometer with a housing, a sensor in the housing, an inner window and an outer dome-shaped window both overlying the sensor. An air inlet duct and an air outlet duct extend in the housing and end in a space confined by the outer window for passing air through the space, from the inlet duct to the outlet duct. The housing is substantially closed such that no outside air flows are allowed into the housing and includes a ventilator, the inlet duct being in fluid communication with a high pressure side of the ventilator, the outlet duct being in fluid communication with a low pressure side of the ventilator. The air blown into the space below the outer window is heated by the ventilator power and optionally by and added electrical heater.
