The ability to forecast the concentration of air pollutants in an urban region is crucial for decision-makers wishing reduce impact pollution on public health through active measures (e.g. temporary traffic closures). In this study, we present a machine learning approach applied forecasts day-ahead maximum value ozone several geographical locations southern Switzerland. Due low density measurem...
Rain gauges (RGs) have been utilized as sensors for local rain monitoring dating back to ancient Greece. The use of a network RGs 2D mapping is based on spatial interpolation that, while presenting good results in limited experimental areas, has scalability because the unrealistic need install and maintain large quantity sensors. Alternatively, commercial microwave links (CMLs), widely spread a...
[1] We infer the vertical profiles of space charge density and electric field intensity above ground by comparing modeling and measurements of the ground‐level electric field changes caused by elevating grounded lightning‐triggering wires. The ground‐level electric fields at distances of 60 m and 350 m were measured during six wire launches that resulted in triggered lightning. The wires were l...
The oscillatory movements of atmospheric air masses has been claimed to be the origin muon flux variation measured at ground level. Using a cosmic ray toolkit (CORSIKA), we simulate cascade scenarios in time scale year and show dependence pattern with proposed model atmosphere.
