Workshop on Effects and Extremes of High Latitude Dust

The 4th Workshop on Effects and Extremes of High Latitude Dust (HLD Workshop) was held in Reykjavik on 13-14 February 2020, organized by the the ICEDUST Association, IBA-FIN-BCDUST-project of MFA of Finland, and EU COST InDust Action.

More than 34 scientists from 10 countries contributed by presenting current research on all aspects of HLD and other aerosols. The Workshop opened multidisciplinary discussions and approaches how to investigate HLD, by leading experts in atmospheric-, cryospheric-, marine-, and soil- sciences.

We thank all the participants for the successful workshop and we look forward to the next 5th HLD Workshop on 10th-11th February 2021!

Final Agenda HLD 2020 (12 Feb 2020)

HLD Workshop aimed on:

  • collecting available info on > 20 new HLD sources to be published in paper
  • engaging Icelandic/international stakeholders to dust monitoring activities
  • topics on other aerosols and air pollutants than HLD (e.g. BC, pollen, sea salt, ..), Arctic air pollution
  • NEW – A Session Starting projects in HLD was opened (main contributors Kerstin Schepanski and Konrad Kandler, Zongbo Shi, Carlos Perez Garcia-Pando, and more)
