UPDATE: DUE TO CURRENT RESTRICTIONS IN TRAVELING the 20th International Symposium for the Advancement of Boundary-Layer Remote Sensing (ISARS) WILL BE POSTPONED.
The 20th International Symposium for the Advancement of Boundary-Layer Remote Sensing (ISARS) is organised by the Finnish Meteorological Institute during June 1st – 5th 2020 in Helsinki, Finland and be hosted by the Finnish Meteorological Institute.
Reliable representation of the continuously evolving atmospheric boundary layer (ABL) structure is essential for numerical weather prediction, forecasting air quality in urban regions, and for climate models. Diurnal evolution of ABL exhibits significant variability between different environments, which makes measuring and modelling ABL processes a very demanding task. The processes occur with temporal and spatial scales ranging from seconds to one day and from meters to kilometres vertically as well as up to 100 km horizontally. For instance, the scales involved with ABL turbulence, which mixes gases, particles, temperature, moisture, and momentum vertically, are mostly outside the scales that models can represent.
Wind speed and direction profiles are also one of the most important but not yet adequately measured atmospheric parameters within the atmospheric boundary layer. Hence, ABL parameterisation schemes are essential in decreasing uncertainties in model predictions. Model parameterisation necessarily requires in-depth studies and long-term data sets, which collectively cover sufficient amount of different type of environments on Earth.
ISARS2020 brings together scientists using ground-based remote sensing methods to monitor and investigating the structure and processes of ABL.
