product description
A complete range of sensors for the measurement of surface albedo
LP PYRA 11 - LP PYRA 06 - LP PYRA 05
General information:
Albedometers are composed of
two pyranometers with thermopile sensors that are mounted back-to-back. An albedometer measures in two directions; one pyranometer is facing upwards (measuring the global solar radiation), the other pyranometer is facing downwards (measuring the reflected solar radiation).
Albedo is the fraction of solar radiation that is reflected from the ground, with respect to incident radiation. By using albedometers, we can calculate the net radiation obtained through the difference between incident global radiation and reflected global radiation.
Delta OHM albedometer series is fully compliant with ISO 9060: 2018 and with the criteria of the WMO “Guide to Meteorological Instruments and Methods of Observation”. Three different versions are available: LPPYRA11 - Spectrally Flat Class A, LPPYRA05 - Spectrally Flat Class B and LPPYRA06 - Spectrally Flat Class C.
All albedometers are passive and do not require any power supply. They are composed in a way that the outputs of the two pyranometers electric signals can be directly sent to a data logger or to an automatic data processor. Moreover, the two pyranometers are coupled in order to have the same sensitivity.
Every pyranometer composing the albedometer is calibrated separately as per the WRR (World Radiometric Reference) standard and is supplied with the relevant report of calibration. These are strong and reliable ground-based instruments, especially designed to be used under all weather conditions. They are suitable for installation in the field.
Main applications:
Climatological research, weather stations, agriculture, environmental research
