Satellite data and algorithms reveal which ships are emitting too much nitrogen
Credit: Leiden University Ships still emit large amounts of nitrogen oxides. Until now it has been impossible to measure this at sea, but that is about to change. Solomia Kulchava has developed an algorithm that combines satellite data to identify which ships are emitting too much. Ms. Kulchava received her Ph.D. June 11th. While automobiles, power plants, and industry are…

Atmospheric Lidar instrument on climate satellite improves understanding of aerosols and clouds
Ground stations of the European research infrastructure ACTRIS play a key role in calibrating data from the EarthCARE satellites. In recent years, these ground stations have been installed and expanded to analyse aerosol particles and clouds using remote sensing instruments such as lidar and radar. Around 50 stations from Europe (photo: TROPOS, Leipzig) and abroad take part in the atmo4ACTRIS…

Reforestation may seem like a simple way to combat climate change, but planted forests often encroach on natural forests, wetlands and grasslands, which can reduce biodiversity, disrupt natural habitats and disrupt carbon and water cycles. Forest cover is…
