Guatemala 2007Plan: a week long deployment of seismic, acoustic, infrared, Doppler radar, digital video, and UV imaging instruments at Santiaguito Volcano, Guatemala.
Goal: these correlated datasets will provide insight into conduit dynamics
Improving the camera
• Improvements to the retrieval of SO2
– Bandpass filters– Calibration cell response curve
– Response to background illumination

Improving the image processing
• Automation of processing:– Image streaming– Cropping– Background
flattening– Average background
calculations– Absorbance
calculations– Concentration
scaling
– SO2 color mapping
