Variability of residence time in the Tropical Tropopause Layer during Northern Hemisphere winter
residence time Tropical Tropopause Layer Northern Hemisphere winter
2009/9/22
For the first time the long-term interannual and spatial variability of residence time (τ) is presented for the TTL between 360 K and 400 K potential temperature (~14 to 18 km altitude). The analysis ...
Classification of Northern Hemisphere stratospheric ozone and water vapor profiles by meteorological regime
Northern Hemisphere stratospheric ozone water vapor profiles meteorological regime
2009/8/25
The subtropical and polar upper troposphere fronts and the polar vortex serve as the boundaries to divide the Northern Hemisphere into four meteorological regimes. These regimes are defined as (1) the...
Polar stratospheric cloud observations by MIPAS on ENVISAT: detection method, validation and analysis of the northern hemisphere winter 2002/2003
Polar stratospheric cloud observations MIPAS ENVISAT northern hemisphere winter
2009/2/7
The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on ENVISAT has made extensive measurements of polar stratospheric clouds (PSCs) in the northern hemisphere winter 2002/2003. A PSC...
Seasonal dependence of peroxy radical concentrations at a Northern hemisphere marine boundary layer site during summer and winter: evidence for radical activity in winter
peroxy radical concentrations Northern hemisphere marine boundary layer site
2009/1/21
Peroxy radicals (HO2+Σ RO2) were measured at the Weybourne Atmospheric Observatory (52° N, 1° E), Norfolk using a PEroxy Radical Chemical Amplifier (PERCA) during the winter and summer of 2002. The pe...
The total ozone field separated into meteorological regimes – Part II: Northern Hemisphere mid-latitude total ozone trends
total ozone field meteorological regimes Northern Hemisphere mid-latitude ozone trends
2009/1/19
Previous studies have presented clear evidence that the Northern Hemisphere total ozone field can be separated into distinct regimes (tropical, midlatitude, polar, and arctic) the boundaries of which ...
Attribution of modeled atmospheric sulfate and SO2 in the Northern Hemisphere for June–July 1997
modeled atmospheric sulfate SO2 Northern Hemisphere
2009/1/16
Anthropogenic sulfate aerosol is a major contributor to shortwave radiative forcing of climate change by direct light scattering and by perturbing cloud properties and to local concentrations of atmos...
Balloon-borne radiometer measurements of Northern Hemisphere mid-latitude stratospheric HNO3 profiles spanning 12 years
Balloon-borne radiometer measurements Northern Hemisphere mid-latitude stratospheric HNO3
2008/12/26
Low-resolution atmospheric thermal emission spectra collected by balloon-borne radiometers over the time span of 1990–2002 are used to retrieve vertical profiles of HNO3, CFC-11 and CFC-12 volume mix...
Observations and analysis of polar stratospheric clouds detected by POAM III and SAGE III during the SOLVE II/VINTERSOL campaign in the 2002/2003 Northern Hemisphere winter
polar stratospheric clouds POAM III SAGE III SOLVE II/VINTERSOL campaign
2008/12/9
The Polar Ozone and Aerosol Measurement and Stratospheric Aerosol and Gas Experiment instruments both observed high numbers of polar stratospheric clouds (PSCs) in the polar region during the second S...
Source-receptor relationships between East Asian sulfur dioxide emissions and Northern Hemisphere sulfate concentrations
Source-receptor East Asian sulfur dioxide Northern Hemisphere
2008/11/13
We analyze the effect of varying East Asian (EA) sulfur emissions on sulfate concentrations in the Northern Hemisphere, using a global coupled oxidant-aerosol model (MOZART-2). We conduct a base and f...
