AVTIS |
AVTIS (All-weather Volcano Topography Imaging Sensor) is a research instrument developed at St Andrews for measuring the size, shape and temperature of volcanic lava domes under virtually any weather conditions.

Overview
- Problem: What is our motivation for building AVTIS?
- Concept: How can mm-waves help?
- Theory: mm-wave imaging, radar and radiometry
- History: AVTIS has come along way since it began in 2004. Here is a brief outline to its development of over the years, and an outline of the future of the project.
Projects
- AVTIS 1: The original instrument; developed and tested 2004 - present.
- AVTIS 2: Upgrade of AVTIS 1 with Doppler and rain measuring capabilities.
- AVTIS 3: Autonomous version of AVTIS 2 that will be constantly fixed on site near the Soufriere hills volcano, Montserrat.
Volconology Workshop
Ground Based Radar for Volcanology workshop, held at the ESSC, University of Reading, January 2008. The presentations made at this workshop are all available here.
Fieldwork
AVTIS 1:
- Local testing: Close range mapping in St Andrews and survey of Balmullo Quarry
- Montserrat 2004: First use in the field, development and limitations
- Arenal 2005: Measuring the movement of lava flows in Costa Rica
- Montserrat 2005: Capturing the growth and temperature of the Soufriere Hills lava dome
