POM II Sky Radiometer

Key features

  • Extended near infrared range
  • Wide operating temperature range
  • Ideal for ground-thruthing satellite data

In addition to the optical system with silicon photo-diode detector of the POM-01, the POM-02 sky radiometer has a second optical system with an Indium Gallium Arsenide infrared detector. The filter wheel has 11 wavebands, providing measurements to 2200 nm. It also has additional UV channels.

The POM-02 must be connected to a PC running the operating software in order to make measurements and store data and like the POM-01 data can be post-processed using the SKYRAD.pack software from SKYNET. Maintenance is minimal; consisting of regular cleaning of the optical windows and checking the desiccant in the radiometer.
