Air pollution sources leading to anthropogenic glaciation of supercooled liquid-water clouds
Toll, Velle; Keernik, Hannes; Rahu, Jorma (University of Tartu, 2024)This dataset lists the air pollution sources leading to anthropogenic glaciation of supercooled liquid-water clouds. The glaciation events were identified in Terra MODIS data. -
Hole punch clouds near Moscow Domodedovo airport
Keernik, Hannes; Toll, Velle (University of Tartu, 2024)We used Terra MODIS satellite data to study hole punch clouds near Moscow Domodedovo airport (55.408611 N 37.906111 E). -
Meteorological conditions characteristic of anthropogenic glaciation of supercooled liquid-water clouds and of anthropogenic CCN perturbations on clouds
Keernik, Hannes; Rahu, Jorma; Toll, Velle (University of Tartu, 2024)We used ERA5 atmospheric reanalysis data to characterise the meteorological conditions characteristic of anthropogenic glaciation of supercooled liquid-water clouds and of cloud perturbations induced by anthropogenic cloud ... -
MODIS and HYSPLIT data to study anthropogenic glaciation of supercooled liquid-water clouds
Keernik, Hannes; Trofimov, Heido; Manshausen, Peter; Christensen, Matthew; Rahu, Jorma; Toll, Velle (University of Tartu, 2024)We used MODIS (https://modis-images.gsfc.nasa.gov/_docs/C6MOD06OPUserGuide.pdf) and HYSPLIT (https://www.ready.noaa.gov/HYSPLIT.php) data to study the anthropogenic glaciation of supercooled liquid-water clouds. We used ... -
Python code for processing MODIS satellite data to study anthropogenic glaciation of supercooled liquid-water clouds
Keernik, Hannes; Toll, Velle (University of Tartu, 2024)The given python code is used to analyse anthropogenic glaciation of supercooled liquid-water clouds downwind of strong industrial point sources of air pollution using Terra MODIS satellite data.
