  2. 1. Bioaerosols and their importance for low-level Arctic clouds

    Author : Gabriel Pereira Freitas; Paul Zieger; Radovan Krejci; Kevin J. Noone; Claudia Mohr; Martin Gallagher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bioaerosols; Aerosols; Clouds; Arctic; Cloud Condensation Nuclei; Ice Nucleating Particles; Sea Spray Aerosol; Environmental Sciences; miljövetenskap;

    Abstract : Bioaerosols are microorganisms or functional parts of them or other biological matter suspended in air. Examples are bacteria, viruses, pollen, spores, or smaller plant debris. In the atmosphere, bioaerosols can play various functional roles, such as facilitating the spread of genetic material. READ MORE

  4. 2. Improving satellite measurements of clouds and precipitation using machine learning

    Author : Simon Pfreundschuh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; precipitation; clouds; remote sensing; machine learning;

    Abstract : Observing and measuring clouds and precipitation is essential for climate science, meteorology, and an increasing range of societal and economic activities. This importance is due to the role of clouds and precipitation in the hydrological cycle and the weather and climate of the Earth. READ MORE

  5. 3. Bringing Visibility in the Clouds : using Security, Transparency and Assurance Services

    Author : Mudassar Aslam; Mats Björkman; Christian Gehrmann; Chris Mitchell; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cloud Security; Trusted Computing; Trustworthy Clouds; Cloud Audits; Security Automation; SCAP; Virtual Machine; Computer Science; datavetenskap;

    Abstract : The evolution of cloud computing allows the provisioning of IT resources over the Internet and promises many benefits for both - the service users and providers. Despite various benefits offered by cloud based services, many users hesitate in moving their IT systems to the cloud mainly due to many new security problems introduced by cloud environments.

  6. 4. Remote sensing of clouds and precipitation using active and passive microwave observations

    Author : Simon Pfreundschuh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microwave remote sensing; precipitation; clouds; hydrometeors;

    Abstract : Global observations of clouds and precipitation are of great importance for weather prediction and the monitoring of the climate. Nonetheless, the currently available record of global observations does not constrain the properties of clouds very well owing to the inherent limitations of the observation systems used to produce them.

  7. 5. Chemodynamics in Star-Forming Molecular Clouds

    Author : Chia-Jung Hsu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stars: formation; hydrodynamics; methods: numerical; ISM: clouds; astrochemistry;

    Abstract : Stars are fundamental building blocks of galaxies. However, the answers to many basic questions about their formation remain elusive. There is no consensus on a theory that can predict the rate of star formation, its clustering properties, and the conditions needed for massive stars to be born. READ MORE
