[ABSTRACT]A newly developed ultraviolet (UV) imaging camera offers a new approach to the ground-based surveillance of volcanic sulphur dioxide (SO2) Using highly sensitive 2-dimensional CCD technology and a bandpass filter centred in the UV region where SO2 selectively absorbs UV light, the camera is able to quantify SO2 within a gas plume in great detail. This study presents results from Sakurajima and Satsuma-Iojima volcanoes, where image sequences were obtained at an unprecedented temporal resolution and revealed interesting variations in SO2 emission rate. The SO2 retrieval technique is also discussed with respect to atmospheric scattering and the use of different UV wavelength filters.
