The scientist’s investigation covers issues in Environmental science, Atmospheric sciences, Cirrus, Troposphere and Relative humidity. His Environmental science research incorporates Meteorology, Climatology, Airplane, Global warming and Cloud physics. His studies deal with areas such as Ice nucleus, Radiative forcing and Supersaturation as well as Atmospheric sciences.
His Cirrus study combines topics from a wide range of disciplines, such as Aerosol, Radiosonde and Nucleation. His Troposphere research is multidisciplinary, incorporating elements of Humidity and Stratosphere. His study explores the link between Relative humidity and topics such as Water vapor that cross with problems in Hygrometer, Southern Hemisphere, Northern Hemisphere and Frost.
His scientific interests lie mostly in Meteorology, Environmental science, Atmospheric sciences, Cirrus and Troposphere. Klaus Gierens combines subjects such as Aviation and Lidar with his study of Meteorology. Many of his Environmental science research pursuits overlap with Humidity, Relative humidity, Climatology, Middle latitudes and Climate model.
His work carried out in the field of Atmospheric sciences brings together such families of science as Ice nucleus, Ozone and Ice crystals. His work deals with themes such as Microphysics, Nucleation, Ice cloud, Aerosol and Flight level, which intersect with Cirrus. His Troposphere study combines topics in areas such as Brightness, Radiosonde, Supersaturation and Water vapor.
Environmental science, Meteorology, Atmospheric sciences, Troposphere and Aviation are his primary areas of study. Klaus Gierens integrates many fields, such as Environmental science and engineering, in his works. His study in Cirrus is interdisciplinary in nature, drawing from both Microphysics and Ice crystals.
He is interested in Radiative forcing, which is a field of Meteorology. As part of one scientific family, Klaus Gierens deals mainly with the area of Atmospheric sciences, narrowing it down to issues related to the Altitude, and often Greenhouse gas and Propulsion. His Troposphere research incorporates elements of Humidity and Water vapor.
Klaus Gierens mainly investigates Meteorology, Atmospheric sciences, Environmental science, Aviation and Climate change. His research in Meteorology intersects with topics in Air traffic control and Fuel efficiency. Specifically, his work in Atmospheric sciences is concerned with the study of Cirrus.
His Cirrus study incorporates themes from Lidar, Air mass and Extinction. The Environmental impact of aviation research he does as part of his general Climate change study is frequently linked to other disciplines of science, such as Economic cost, therefore creating a link between diverse domains of science. His Ice crystals study integrates concerns from other disciplines, such as Nucleation, Large eddy simulation, Anthropogenic cloud, Liquid water content and Ice cloud.
