Temperature and humidity dependence of secondary organic aerosol yield from the ozonolysis of β-pinene
secondary organic aerosol yield ozonolysis β-pinene
2009/6/16
The temperature dependence of secondary organic aerosol (SOA) formation from ozonolysis of β-pinene was studied in a flow reactor at 263 K–303 K and 1007 hPa under dry and humid conditions (0% and 26%...
Airborne observations of total RONO2: new constraints on the yield and lifetime of isoprene nitrates
Airborne observations yield lifetime isoprene nitrates
2009/3/13
Formation of isoprene nitrates (INs) is an important free radical chain termination step ending production of ozone and possibly affecting formation of secondary organic aerosol. Isoprene nitrates als...

Absolute rate constantl O(3P) yield O(1D)+N2O reaction
2008/11/24
The absolute rate constant for the reaction that is the major source of stratospheric NOx, O(1D)+N2O → products, has been determined in the temperature range 227 K to 719 K, and, in the temperature ra...
Global modeling of secondary organic aerosol formation from aromatic hydrocarbons: high- vs. low-yield pathways
secondary organic aerosol aromatic hydrocarbons high- vs. low-yield pathways
2008/11/6
Formation of SOA from the aromatic species toluene, xylene, and, for the first time, benzene, is added to a global chemical transport model. A simple mechanism is presented that accounts for competiti...
Particle mass yield in secondary organic aerosol formed by the dark ozonolysis of α-pinene
secondary organic aerosol dark ozonolysis α-pinene
2008/11/4
The yield of particle mass in secondary organic aerosol (SOA) formed by dark ozonolysis was measured for 0.3–22.8 ppbv of reacted α-pinene. Most experiments were conducted using a continuous-flow cham...
Impact of Climate Change on Spring Wheat Yield in Yellow River Irrigation Region of Ningxia
Yellow River irrigation region Ningxia climate warming spring wheat
2010/2/21
Temperatures from early March to early July during 1961-2004, at 10 stations in the Yellow River irrigation region of Ningxia were analyzed. The results show that the temperature during the growing se...
