PAR develops sensing instruments and provides consulting services to the scientific, commercial, and defense communities. We have deployed wide-spectral range instruments (including both hardware and software) in NSF Antarctic field campaigns, including installing and debugging systems on-ice during a field campaign measuring ground water melt in the Antarctic Dry Valleys, and developed and delivered ruggedized instruments for terrestrial and spaceborne applications, including multiple optical/thermal imaging systems for evaluating permafrost in high altitude environments.
