1. 11. Land-atmosphere interactions and regional Earth system dynamics due to natural and anthropogenic vegetation changes

   Författare :Minchao Wu; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :land-atmosphere interactions; RCA-GUESS; LPJ-GUESS; Vegetation dynamics; Fire;

   Sammanfattning : Observation and modelling studies have indicated that the global land surfaces have been undergoing significant changes in the past few decades, driven by both natural and anthropogenic factors, such as changes in ecosystem productivity, fire and land use. Land surface changes can potentially influence local and regional climate through land-atmosphere interactions. LÄS MER

3. 12. Ice out of Fire : Ice and cloud condensation nucleation of aerosol particles emitted from controlled soot generation and combustion of renewable fuels

   Författare :John Falk; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soot; BC; Immersion freezing; IN; INP; CCN; SPIN; CCNC; MiniCAST; Cold Stage; Cook Stove;

   Sammanfattning : Aerosol particles, small solid or liquid particles suspended in a gas, are found everywhere in the atmosphere. Air pollution from such particles, mainly soot from combustion-derived activity is a leading cause of premature deaths in the world and have a large effect on the climate. LÄS MER

4. 13. Extreme solar particle storms and links to solar activity inferred from cosmogenic radionuclides in ice cores

   Författare :Chiara Paleari; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ice cores; cosmogenic radionuclides; Solar storms; 10Be; 36Cl; Solar energetic particles;

   Sammanfattning : During solar storms, large amounts of solar energetic particles (SEP) are accelerated into the interplanetary medium and sometimes hit Earth. These events, known as SEP events, can have harmful impacts on our modern society by affecting spacecrafts and potentially astronauts in space. LÄS MER

5. 14. Cloud Droplet Forming Potential of Ageing Soot and Surfactant Particles : Laboratory research and Köhler modelling

   Författare :Cerina Wittbom; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :Hygroscopicity; CCN; BC;

   Sammanfattning : Aerosol particles affect Earth’s climate system by scattering and absorbing light. The perturbation of the climate system caused by a change in aerosol configuration due to anthropogenic emissions has recently improved. LÄS MER

7. 15. Black Death - Blue Skies - White Clouds : Water Vapour Uptake of Particles Produced from Traffic Exhaust and their Effect on Climate

   Författare :Cerina Wittbom; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCN ACTIVATION; Soot; water vapour; climate; SOA; Traffic emission; Fysicumarkivet A:2017:Wittbom;

   Sammanfattning : Aerosol particles are everywhere in the air around us, regardless of whether you are in a busy city or in the serene Arctic. Airborne particles can be produced naturally or anthropogenically, and their properties changes during the time they spend in the atmosphere. LÄS MER
