TAU Radiometers / Opacity Measurements

Tau-225 / Tau-350 Radiometer

The RPG-Tau-225 and RPG-Tau-350 radiometers are designed for the estimation of atmospheric opacity (optical thickness, tau) in the observation bands of radio astronomy applications. Both of these sub-mm frequencies can easily be combined in one single instrument. Other frequencies are available.

Model	Frequencies	Applications	Description
Tau-225	225 GHz	Atmospheric opacity, radio astronomy.	The RPG-Tau-XXX series of tipping radiometers is meant for measurements of atmospheric opacity (Tau) in variable observation directions. The main application is opacity estimation for the precise observing frequencies in radio astronomy experiments.
Tau-225-350	225 & 350 GHz	Atmospheric opacity, radio astronomy.
