Although there are a large number of INP sources, the ice nucleating abilities of aerosol particles originating from oceans, deserts, and wildfires are poorly described at tropical latitudes. To fill this gap in knowledge, the National Autonomous University of Mexico micro-orifice uniform deposit impactor droplet freezing technique (UNAM-MOUDI-DFT) was constructed to measure the ice nucleating activity of aerosol samples that were collected in Sisal and Mérida, Yucatán (Mexico) under the influence of cold fronts, biomass burning (BB), and African dust (AD) intrusions during five short-term field campaigns between January 2017 and July 2018. The three different aerosol types were distinguished by their physicochemical properties. Marine aerosol (MA), BB, and AD air masses were found to contain INPs; the highest concentrations were in AD (from 0.071 to 36.07 L-1 at temperatures between -18 and -27 °C), followed by MA (from 0.068 to 18.90 L-1 at temperatures between -15 and -28 °C) and BB (from 0.063 to 10.21 L-1 at temperatures between -20 and -27 °C). However, MA had the highest surface active site densities (ns) between -15 and -30 ° C. Additionally, supermicron particles contributed more than 72 % of the total INP concentration independent of aerosol type.. © 2021 Copernicus GmbH. All rights reserved.
