Forest soil stores water, carbon and nutrients for trees and also provides a habitat for living organisms. When managing forests, it is particularly important to work in a way that protects the soil and to correctly assess soil moisture for that purpose. A new study by the University of Göttingen in collaboration with the Czech Mendel University shows that previous methods of moisture measurement are inadequate. Satellite data can help to better understand the soil moisture dynamics of forest soils. This research has implications for best practice in forest management. The findings will help people adapt to a changing climate and to refine and inform prediction models. The results were published in the Journal of Hydrology: Regional Studies.

 

Student researchers put UTA on national stage. Program allows students to present original research, network with professionals and future employers. 

Researchers from Tsung-Dao Lee Institute (TDLI) & School of Physics and Astronomy (SPA), Shanghai Jiao Tong University (SJTU) have proposed a lutetium yttrium oxyorthosilicate (LYSO) crystal electromagnetic calorimeter (ECAL)^[1], designed for the DarkSHINE experiment^[2-6]. By precisely measuring the energy loss of electrons after their interaction with a target, the ECAL is designed to search for invisibly decay products of dark photons. Featuring excellent energy resolution and strong radiation tolerance, this calorimeter significantly enhances the sensitivity of dark photon detection.

Ozone pollution is a global environmental concern that not only threatens human health and crop production, but also worsens global warming. While the formation of ozone is often attributed to anthropogenic pollutants, soil emissions are revealed to be another important source. The Hong Kong Polytechnic University (PolyU) researchers have examined global soil nitrous acid (HONO) emissions data from 1980 to 2016 and incorporated them in a chemistry-climate model to unveil the pivotal role soil HONO emissions play in the increase of the ozone mixing ratio in air and its negative impact on vegetation.

While scientists have long studied currents of large eddies, the smaller ones — called submesoscale eddies — are notoriously difficult to detect. These currents, which range from several kilometers to 100 kilometers wide, have been the “missing pieces” of the ocean’s puzzle — until now. Using data from the new Surface Water and Ocean Topography (SWOT) satellite, a Texas A&M researcher and his collaborators at JPL, CNES and Caltech finally got a clear view of these hard-to-see currents, and they are a lot stronger than anyone thought.
