1. 1. Consequences of Adaptation for Risk : In Nepal and the Maldives

   Författare :Lama Phudoma; Avdelningen för Riskhantering och Samhällssäkerhet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptation; risk; communities; Nepal; Maldives;

   Sammanfattning : Throughout time, communities have adapted to changes in their environment and, in doing so, have addressed risksthat threaten the things they value. The need to adapt is considered more urgent now than ever, notably given thecurrent focus on climate risk. Typically, adaptation is presented as a solution to reduce such risks. LÄS MER

3. 2. Characterization of soot in air and rain over southern Asia

   Författare :Erik J. Engström; Caroline Leck; Henning Rodhe; Paolo Laj; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soot; black carbon; atmospheric concentration; light absorption; wet deposition; scavenging; wash-out ratio; South-Asia.; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap;

   Sammanfattning : Filter-based optical measurements of light absorbing particulate matter at awavelength of about 550 nm, here referred to as soot, in air and rainwaterhave been performed during the period from 1st June 2005 to 31th May 2009at Godavari in Nepal, Sinhagad in India and Hanimaadhoo in The Maldives.A method for determination of water-insoluble light absorbing matter inrainwater has been developed.

4. 3. Multiple perspectives on absorbing aerosols over the northern Indian Ocean and Asia

   Författare :Friederike Höpner; Frida Bender; Annica Ekman; Heike Wex; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosols; black carbon; air pollution; South Asia; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : Aerosol particles in the atmosphere scatter and absorb solar radiation, and thereby affect the Earth's energy budget, but the magnitude of the overall radiative effect due to aerosol-radiation interactions is uncertain. In particular, the impact of absorbing aerosol particles, mainly black carbon (BC), organic carbon and dust, is not completely understood. LÄS MER

5. 4. Studies of Tropospheric and Stratospheric Aerosol using Ion Beam Analysis

   Författare :Giorgos Papaspiropoulos; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmosphere; Aerosols; troposphere; stratosphere; ion beam analysis; PIXE; impactors; particulate sulphur; chemical speciation; elemental analysis; thermography; Physics; Nuclear physics; Fysik; Metrology; Kärnfysik; physical instrumentation; Metrologi; fysisk instrumentering; Fysicumarkivet A:2001:Papaspiropoulos;

   Sammanfattning : Atmospheric aerosol particles are believed to have an impact on the radiative forcing of the earth's surface. The predicted results indicate a net cooling effect on the global climate, however there are few studies available to substantiate this and experimental data are needed. LÄS MER

7. 5. Isotope-based constraints on sources and processing of black carbon, carbon monoxide, and brown carbon in South Asia

   Författare :Sanjeev Dasari; Örjan Gustafsson; August Andersson; Jos Lelieveld; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; South Asia; Air Pollution; Short-Lived Pollutants; Atmospheric Abundance; Model-Observation Mismatch; Radiocarbon; Stable Isotopes; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : The highly populated South Asian region is facing rapid economic growth and urbanization. Here, both climate- and health-affecting atmospheric agents such as light-absorbing aerosols black carbon (BC) and brown carbon (BrC), trace gas carbon monoxide (CO), are often found in relatively high levels compared to in other regions.
