The elevation at which wildfire smoke is injected into the atmosphere has a strong influence on how the smoke is dispersed, is a key input to aerosol transport models and can influence air quality far from the burning areas via longrange transport. Here, we analyze a record of aerosol smoke plume heights derived from observations over Greece made by the Multi-angle Imaging SpectroRadiometer (MISR) instrument on board the NASA Earth Observing System Terra satellite. Two case studies of wildfires over Greece (Chios and Agio Oros) are presented to illustrate the methodology followed. The impact of those fires on air quality at surface is examined using high resolution advanced in-situ instrumentation. Our analysis clearly indicates the importance of long range transport on air quality as emissions from wildfires strongly affect atmospheric aerosol chemical composition and concentrations at surface.
