Q7.1-L REBS Net Radiometer

Overview

The Q7.1 measured the difference between incoming and outgoing radiation. A thermopile output a voltage proportional to the temperature difference between the top and bottom surfaces of the radiometer.

Detailed Description

The Q7.1 measured the difference between incoming and outgoing radiation. A thermopile output a voltage proportional to the temperature difference between the top and bottom surfaces of the radiometer.

As shading and reflection represent sources of error to the net radiation measurement, the Q7.1 was typically deployed at some distance to the primary instrument mount. A simple vertical pipe affixed with a CM210 mount was recommended for this purpose.

Nominal calibration factors: 9.6 W m-2 mV-1 for positive values; 11.9 W m-2 mV-1 for negative values.
