An HF-Radiometer in active mode

At the IPC-XIII, Davos Instruments has been successfully operating a Hickey-Frieden (HF) radiometer from Eppley Laboratory Inc. in active mode, using a slightly modified control unit Linard.

It has been found that the HF radiometer is very well suitable for active operation. While the HF-radiometer is traditionally operated in the passive mode, it has all the necessary features needed for active mode operation.

First results have been presented in the symposium of the IPC-XIII, a preprint of the proceedings-article is available here.

Linards in Lindenberg

Two Linard control units have been successfully installed at the Deutscher Wetterdienst (DWD) in Lindenberg, Germany. DWD has upgraded its two PMO6 reference radiometers with the new Linard control unit, replacing the older PMO6cc control units.

As a special feature, one of the Linard control units is also controlling and collecting data from the Hickey-Frieden Radiometer (on the left side of the tracker).
