A Parameterized Method for Air-Quality Diagnosis and Its Applications
Advances in Meteorology, 2012 A parameterized method is developed to diagnose the air quality in Beijing and other cities with an index termed (parameters linking air-quality to meteorological elements PLAM) derived from a correlation between PM10 and relevant weather elements based ...

Methane exchange at the peatland forest floor – automatic chamber system exposes the dynamics of small fluxes [PDF]
Biogeosciences, 2017 We measured methane (CH4) exchange rates with automatic chambers at the forest floor of a nutrient-rich drained peatland in 2011–2013. The fen, located in southern Finland, was drained for forestry in 1969 and the tree stand is now a mixture of Scots ...

Atmospheric Structure and Composition
, 2009 Titan's atmosphere is predominantly N2 with CH4 the next most abundant molecule. It has a mole fraction of 0.05 just above the surface decreasing to 0.014 in the stratosphere. Above the homopause (~800–850 km), it increases to 0.12 at the exobase. The third abundant molecule is H2 with a tropospheric mole fraction of 0.001 increasing to 0.004 at ~1000 ...

Measurement report: The effects of SECA regulations on the atmospheric SO2 concentrations in the Baltic Sea, based on long-term observations on the Finnish island, Utö [PDF]
Atmospheric Chemistry and PhysicsThe designation of the Baltic Sea as a sulfur emission control area (SECA) in May 2006, with subsequent tightening of regulations in 2010 and 2015, has reduced the sulfuric emission from shipping traffic.

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
