Background

Weather monitoring is an essential component of the AVERT network because many volcanic data products depend on local atmospheric conditions. In particular, gas fluxes derived from MultiGAS and Scanning DOAS require accurate wind speed and direction to convert concentration data into emission rates.

Weather stations also provide context for interpreting soil CO₂ and temperature data, since barometric pressure, rainfall, and temperature can influence shallow degassing processes. Continuous meteorological records therefore serve as both standalone datasets and critical inputs to other volcanic monitoring systems.
