POM-01 Sky Radiometer

POM-01 Sky Radiometer

The POM-01 sky radiometer uses a single detector and a rotating filter wheel to measure radiation in seven narrow wavebands from 315 nm to 1020 nm. The dedicated sun tracker enables measurement either directly from the sun or at user-defined angles away from the sun.

The instrument has a base with levelling feet and a sun sensor for active tracking. Installation is quick and simple. A precipitation sensor is included so that the radiometer is pointed downwards during rain to keep the optics clean.

POM-01 must be connected to a PC running the operating software in order to make measurements and store data. The software allows comprehensive user selection of the scanning modes.

POM-01 is used in the Asia-Pacific SKYNET network and for aerosol monitoring and satellite ground-truthing around the world. The POM data can be post-processed to provide parameters including aerosol optical depth, scattering coefficients, aerosol distribution and energy distribution. The SKYRAD.pack software for this is a free download from the SKYNET site at http://skyrad.sci.u-toyama.ac.jp/sky_info.html.
