The LINUS UV Imaging Spectrometer}

We present an overview of the Naval Postgraduate School's new LINUS instrument. This is a spectral imager designed to observe atmospheric gas plumes by means of absorption spectroscopy, using background Rayleighscattered daylight as an illumination source. It is a pushbroom instrument, incorporating a UV-intensified digital camera, interchangeable gratings and filters, and a DC servo-controlled...

Measurements of SO[2] profiles in volcanic plumes from the NASA Tropospheric Emission Spectrometer (TES)

[1] Satellite measurements are now recognized as a key element for the early detection and characterization of volcanic eruptions, in particular in the context of aircraft routing. A common tracer of volcanic plumes is sulfur dioxide (SO2), which so far has been measured by ultraviolet-visible (UV-vis) instruments and multispectral infrared (IR) sounders. Here we report the first SO2 vertical p...

Retrieval of sulfur dioxide from a ground-based thermal infrared imaging camera

Recent advances in uncooled detector technology now offer the possibility of using relatively inexpensive thermal (7 to 14 μm) imaging devices as tools for studying and quantifying the behaviour of hazardous gases and particulates in atmospheric plumes. An experimental fast-sampling (60 Hz) ground-based uncooled thermal imager (Cyclops), operating with four spectral channels at central waveleng...
