GCSO2-1 SO2 Gas Camera

The Resonance GCSO2-1 is a UV-sensitive camera that compares images in two spectral bands to produce concentration maps of SO2 plumes. This method is based on differential optical absorption spectroscopy (DOAS) methodology for remote sensing of atmospheric gases (Refs 1-12).

RMD Expedition Resonance Mini DOAS RMD (I, II, Min)

RMD is a compact UV/visible spectrometer system designed for remote sensing of atmospheric gases and is the first of a series of spectrometers designed to have multi-gas capabilities.


MicroMAPS is a gas filter correlation radiometer capable of detecting trace atmospheric gasses by remotely sensing their infrared (IR) absorption characteristics.

COSPEC Correlation Spectrometer

SO2 and NO2, gases selectively and characteristically absorb light from scattered solar radiation (skylight) as it passes through the atmosphere.

Resonance UAV Gas Monitoring System

Being an easily portable system, the Resonance Gas Camera is designed to be small enough to be carried by an unmanned Aerial Vehicle (UAV).
