  • Albedometers

    LP PYRA 06 DeltaOHM - Delta OHM S.r.L.

    LP PYRA 05 is constructed starting from two 1st class* pyranometers and theLP PYRA 06 starting from two 2nd class* pyranometers (* according to ISO 9060standards and to specifications published by the World Meteorological Organization).An albedometer basically consists of two pyranometers, mounted back-toback,one looking upward (sky) and one downward (earth). The upward pyrametermeasures the incident global radiation (direct radiation + diffuse radiation)striking the ground, while the downward one, measures the global radiationreflected from the ground. The outputs of the two pyranometers electric signals(the two pyranometers which made up of the LP PYRA 05 are couppled in orderto have the same sensitivity) can be directly sent to a data logger or to an automaticdata processor. Albedo is the fraction of solar radiation that is reflectedfrom the ground, with respect to incident radiation:ALBEDO =Reflected Global RadiationIncident Global RadiationBy using albedometers, we can calculate the net radiation obtainedthrough the difference between incident global radiation and reflectedglobal radiation.Delta Ohm albedometers operate within 0.3 μm ÷3 μm spectral range. No powersupply is needed, as the two pyranometers generate a voltage which is usuallyequal to:10mVkW • m-2Every pyranometer composing the albedometer is calibrated separately as perthe WRR (World Radiometric Reference) standard and is supplied with the relevantReport of Calibration.These are strong and reliable ground-based instruments, especially designedto be used under all weather conditions. They are suitable for installation of thefield.Recommended use: climatological research, weather stations, road weatherstations, agriculture stations, etc…

  • Albedometers

    LP PYRA 05 - Delta OHM S.r.L.

    The LP PYRA 05 albedometer measures the net global radiation, as well as the albedo of grounds (albedo is the ratio between diffuse radiation from a determined surface and the quantity of radiation that arrives on the surface). The LP PYRA 05 is manufactured mounting two LP PYRA 02 pyranometers in one housing only. The two pyranometers, one measuring the incident radiation striking the ground [ ↓ ] and the other one measuring the reflected radiation [ ↑ ] are combined in such a way to have the same sensitivity. The signals of the two pyranometers are obtained from the output cable. These signals can be processed to get the desired physical quantity.
