This repository contains the raw data associated with the analysis of aeolian remobilisation of volcanic ash in Patagonia. This project focuses on the design and implementation of dedicated samplers to collect primary tephra, resuspended particles (airborne), atmospheric parameters, and air quality conditions, in collaboration with the communities in Argentina. This dataset is associated with the following scientific publications (in preparation) Dominguez et al. (in prep). The Role of Community Participation in Co-Producing Knowledge on Aeolian Remobilisation Fries et al. (in prep). Innovative and cost-effective instrumentation to study volcanic ash remobilisation by aeolian processes: application at Copahue volcano (Argentina Content Data is structured in 3 folders: GIS, containing the geolocation of collectors. Sampling, containing the templates for sampling records and field photographs. Electronic devices, containing the raw results of weather stations and calculations of wind velocity (U*).
