Brightness Method to monitor H2O emissions
During my PhD, I developed a new method to monitor the emissions of water vapor from active volcanoes. This method is based on a new model that correlates the water content of volcanic gas plumes with the digital brightness measured with digital images. This work was developed in collaboration with my colleagues from the Earth Observatory of Singapore (EOS) and the Philippine Institute of Volcanology and Seismology (PHIVOLCS), and was published in Journal of Geophysical Research.
A news on this subject was posted at GeoSpace, a blog on Earth and Space Science managed by AGU:
Experimental setup to test the brightness method to monitor volcanic degassing.
A cloud of droplets is created with an ultrasonic humidifier.
The cloud is recorded with a digital camera and the images
are analyzed according to our model.
