Sea2Cloud - Tangaroa - ASIT - PSM - Level 0

ASITs (Air-Sea Interface Tanks) are an experimental set-up consisting of two 1.83m3 chambers half filled with seawater from the Chatham Rise area. Three experiment of two days each were lead with three different seawaters : Subtropical, Subantarctic and frontal seawater. Clean marine air was continuously flushed in the chambers and analyzed at the outlet, resulting in a 40 minutes residence time. A single gases and aerosols instrument set was used for both ASITs, ambient and flushing air through a four-port entrance electrovalve switching every 20 minutes. The full set-up is described in Sellegri et al. 2023, Rocco et al. 2021 and Chamba et al. 2023.

This file contains the aerosol total concentrations measured by a Particle Size Magnifyier (PSM) at a 1 min time resolution during ASITs experiments. Two different size cut were used: 1nm and 3 nm.
