Fig. 1: Boundary layer height, temperature and particulate matter during the warm air-mass intrusion event.
From: A central arctic extreme aerosol event triggered by a warm air-mass intrusion
A Evolution of the boundary layer height (BLH, left axis, solid black line and lilac markers) and temperature (right axis, solid blue line), the unshaded area represents the warm air-mass intrusion event and is the focus of this study. B Particulate matter with diameter smaller than 1 µm (PM1, left axis, purple triangles) and precipitation rate (right axis, shaded area), the two peaks of the warm intrusion event are separated by precipitation.
