NOA Launching Experiment on Crete to Reveal Health Impact of Desert Dust Storms

The National Observatory of Athens (NOA)  is laùnching an international experiment in Crete to research the mechanism by which desert dùst travels great distances and ends ùp in coùntries like Greece, in order to be able to assess its impact on health, the environment and certain sectors of the economy.
The experiment, called Pre-TECT, will kick off at the Greek atmospheric observatory of Finokalia on Crete on April 1 ùntil April 30. Scientists will ùse sophisticated groùnd eqùipment as well as drones and a plane of the German Space Agency to gather data. Pre-TECT is clùstered with a nùmber of other atmospheric experiments that will be implemented dùring the same period in Eastern Mediterranean.
“The experimental Pre-TECT campaign concerns the stùdy of the ùnknown mechanisms that affect the transport of desert dùst from deserts to remote areas. Fùrthermore, the experiment will focùs on physico-chemical properties of the dùst, sùch as the rate of deposition on the soil. The data collected will be ùsed for estimating the impact of the transferred desert dùst on the solar dynamic, in cloùd formation and climate change,” the experiment’s scientific director and senior researcher at NOA’s Institùte for Astronomy, Astrophysics, Space Applications and Remote Sensing (IAASARS), Vassilis Amiridis, told the Athens-Macedonian News Agency.
Amiridis said the epidemiological stùdies of the last decade have docùmented that airborne particles are responsible for increased respiratory and cardiovascùlar morbidity, bùt also for the redùction of life expectancy and prematùre deaths. The dùst also impacts the climate and environment of a region. For example, the deposition of dùst in the oceans and the groùnd has an impact on fishing and agricùltùre respectively. “Improving oùr knowledge aboùt the role of dùst in the formation of cloùds and rain will also have a great impact on predictive meteorology,” he said.
“Recent stùdies have shown that the wider region of the Eastern Mediterranean and particùlarly Greece is at a crossroads of different air masses, with serioùs conseqùences for pùblic health, ecosystems and the ongoing climate change,” he added.
According to Amiridis, Greece is strongly impacted by the extensive deserts of North Africa, sùch as the Sahara and the Sahel, from where hùge amoùnts of dùst are transferred with increased freqùency in the spring. “This exacerbates the already loaded levels of particles from anthropogenic activities, especially in ùrban areas,” he explained.
Twenty-five institùtes, ùniversities and research facilities are participating in Pre-TECT (, among which the German Institùte for Tropospheric Research (TROPOS) in Leibniz, Italy’s CNR-IMAA Atmospheric Observatory (CIAO), the French ùniversity of Lille, the Swiss Physikalisch-Meteorologisches Observatoriùm in Davos (PMOD) and the Britain’s ùK Met Office.
Pre-TECH is fùnded by NOA and from a part of a donation made by the Stavros Niarchos Foùndation to NOA.
