The purpose of the workshop will be to use, assess, and evaluate current and new techniques and technologies that are used to measure, collect, and interpret volcanic gases.

The broader goals are to develop our capabilities to measure and quantify volcanic gas emissions
(1) to better understand volcanic eruptions, magma degassing, magma ascent, and volcanic plumbing systems;
(2) to better forecast eruptions; and
(3) to better characterize volcanic gas inputs into the atmosphere, and the fates of these gases during atmospheric transport.

The workshop will be field-based, so that different groups can make measurements simultaneously for
(1) comparative purposes
(2) cross-calibration
(3) better understanding of volatile systems and volcano degassing mechanisms
(4) addressing issues related to plume chemistry and plume-atmosphere interactions.

Those of you who are involved in the measurement of volcanic gases are warmly encouraged to participate in the workshop. The types of measurements will span a full range, including but not limited to in situ techniques (e.g., fumarole and plume sampling), diffuse soil degassing (e.g., CO2, radon fluxes by chamber techniques, eddy correlation, etc.), ground-based remote sensing (e.g., COSPEC, FTIR, etc.), and satellite remote sensing (e.g., TOMS, ASTER, MODIS). In the tradition of CCVG, the field workshop will be followed up by comparison of the sampling and measurement techniques and the results obtained.

Another important aspect of the workshop will be the opportunity to test and evaluate new sensors and new technologies. Since there will be a variety of simultaneous measurements being made, we encourage you to consider testing and using your new instrumentation during the workshop. Examples might include sensors for continuous gas monitoring, mini-DOAS, lidar, etc.

We anticipate that researchers from a range of backgrounds and viewpoints will participate in the workshop. In this way, we hope to foster exchange of ideas among people interested in technique development, modelling of degassing processes, practical applications to restless volcanoes, and tropospheric plume chemistry.
