Short summary
While measuring sulfur dioxide fluxes in volcanic plumes with a UV-sensitive camera, the wind direction can influence the retrieved fluxes. If the volcanic plume is tilted in the field of view of the camera, it can lead to over- or underestimations of the determined fluxes. This paper presents a method to deal with such a circumstance. Additionally, it provides the possibility to determine the wind direction of the plume directly from the image time series themselves.
