“…As supersaturation (SS) increases from 0.1 % to 0.7 %, the median <span class="inline-formula"><i>N</i>_CCN</span> increases from 399 to 2144 cm<span class="inline-formula">⁻³</span>, which represents 10 % to 48 % of the total particle number concentration with a diameter range of 10–800 nm, while the median hygroscopicity factor (<span class="inline-formula"><i>κ</i></span>) and critical diameter (<span class="inline-formula"><i>D</i>_c</span>) decrease from 0.27 to 0.19 and from 176 to 54 nm, respectively. (2) Aerosol particle activation is highly variable across seasons, especially at low-SS conditions. …”
