Using Machine Learning Methods to Identify Particle Types from Doppler Lidar Measurements in Iceland
Publikováno v:
Remote Sensing, Vol 13, Iss 13, p 2433 (2021)
Doppler lidars are used worldwide for wind monitoring and recently also for the detection of aerosols. Automatic algorithms that classify the lidar signals retrieved from lidar measurements are very useful for the users. In this study, we explore the

Ground-based lidars and ceilometers are widely used for dust and volcanic ash observation around the world. This is particularly interesting in Iceland where high-altitude dust events occur frequently during strong wind conditions and volcanic erupti

With increasing air temperature in a warming climate the soil temperature also increases. Such changes impact flora, fauna and natural hazards. Thus, it is important to monitor soil temperature. In Iceland, the highland station Hveravellir has the lo

The first meteorological measurement in Surtsey were conducted before the eruption ended in 1967 and since 2009 there have been continous automatic measurements on the island. Here we give the first comprehensive analysis of the climate of Surtsey, b
