1. A database of single scattering properties for hydrometeors at microwave and sub-millimetre frequencies
Sammanfattning : Remote sensing observations of hydrometeors (ice or liquid water particles) at microwave and sub-millimetre wavelengths provide important input to numerical weather forecasting through data assimilation and give insight to cloud processes that are relevant for climate prediction. The utilization of such measurements requires information on the single scattering properties (SSP), i. LÄS MER
2. A Database of Microwave Single Scattering Properties of Ice Hydrometeors
Sammanfattning : Microwave remote sensing by satellites is important for global observations of ice hydrometeors. Interpretation of the measurements requires sufficiently accurate knowledge of hydrometeors’ interaction with photons, i.e. article scattering and absorption. LÄS MER
3. Remote sensing of clouds and precipitation using active and passive microwave observations
Sammanfattning : 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. LÄS MER
4. Improving satellite measurements of clouds and precipitation using machine learning
Sammanfattning : 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. LÄS MER
5. Modeling aerosol-cloud interactions in the Arctic
Sammanfattning : Clouds have a large impact on Earth’s energy balance, especially in the Arctic. Through their warming or cooling effect on the surface, clouds can play a critical role in the onset of melting and freezing of Arctic sea ice, which itself has a large effect on energy and moisture fluxes between the ocean and the atmosphere.
