ASI6Atmospheric measurements from the local to the regional scale: Concepts, new technologies and scientific progress
|Convener: Frank Beyrich | Co-Convener: Fred C. Bosveld|
Measurements are essential to provide information on the actual state of the atmosphere for nowcasting purposes, for climate monitoring, for assimilation into numerical weather prediction (NWP) systems and to improve our understanding of atmospheric processes and their role in the climate system. In particular, there is a strong need for complex observations suitable to develop, improve and validate parameterizations used in NWP and climate models and to provide ground-truth against which to compare atmospheric parameters derived from satellite data. Land surface heterogeneity poses special challenges to match scales between experimental techniques, models and satellite images.
This session is intended to give a forum to discuss recent developments and achievements in local to regional measurement concepts and technology. There will be a special emphasis on measurements which seek to improve our understanding of complex atmospheric processes – especially those characterising interactions in the climate system – through obtaining comprehensive data sets. The session will also include consideration of novel measurement approaches under development for future operational use, and the performance of new measurement techniques. The focus is on measurements of the energy and water cycle components, such as wind, temperature and humidity profiles (mean values and spatial / temporal statistics), heat and water storage in the soil, radiation and turbulent fluxes of energy and momentum, and cloud and precipitation physics. Reports on aerosol and trace gas measurements are also welcomed as far as they contribute to understanding physical processes in the atmosphere.
Techniques may cover in-situ and remote sensing measurements. Contributions are also invited that make use of advanced data sets for model assessment and satellite data validation. In particular we invite meteorological sensor and measurement system developers to report scientific progress in technology, sensor design, test results and inter-comparison experiments.
