The concentrations of the hydrogen radicals OH and HO2 in the middle and upper troposphere were measured simultaneously with those of NO, O3, CO, H2O, CH4, non-methane hydrocarbons, and with the ultraviolet and visible radiation field. The data allow a direct examination of the processes that produce O3 in this region of the atmosphere. Comparison of the measured concentrations of OH and HO2 with calculations based on their production from water vapor, ozone, and methane demonstrate that these… 

The photochemistry of acetone in the upper troposphere: A source of odd‐hydrogen radicals

This paper summarizes measured photodissociation quantum yields for acetone in the 290‐320 nm wavelength region for pressures and temperatures characteristic of the upper troposphere. Calculations

Reaction between CH3O2 and BrO radicals: a new source of upper troposphere lower stratosphere hydroxyl radicals.

Global model results suggest that the decomposition of H2COO to form OH could lead to an enhancement in OH of up to 20% in mid-latitudes in the upper troposphere and in the lower stratosphere enhancements in OH are inferred from model integrations.

Sources of upper tropospheric HOx: A three-dimensional study

The sources of odd hydrogen radicals (HOx = OH + HO2) in the upper troposphere are investigated and quantified using a three-dimensional model. While the reaction of O(1D) with water vapor

Photochemistry of HO x in the upper troposphere at northern midlatitudes

The factors controlling the concentrations of HOx radicals (= OH + peroxy) in the upper troposphere (8–12 km) are examined using concurrent aircraft observations of OH, HO2, H2O2, CH3OOH, and CH2O

Ozone production efficiencies of acetone and peroxides in the upper troposphere

HOx concentrations in the upper tropical troposphere can be enhanced by the presence of acetone and the convective injection of peroxides. These enhancements in HOx might be expected to increase

NOy partitioning from measurements of nitrogen and hydrogen radicals in the upper troposphere

Recent studies using NO, NOy, OH and HO2 (HOx) observations have postulated acetone and convection of peroxides as significant sources of HOx in the upper troposphere (UT). This work focuses on the

Evidence from the Pacific troposphere for large global sources of oxygenated organic compounds

The tropospheric composition of oxygenated organic species is characterized, using data from a recent airborne survey conducted over the tropical Pacific Ocean, and it is suggested that oxygenated species could be formed via the oxidation of hydrocarbons in the atmosphere, the photochemical degradation of organic matter in the oceans, and direct emissions from terrestrial vegetation.

Observations of HO x and its relationship with NO x in the upper troposphere during SONEX

Simultaneous measurements of the oxides of hydrogen and nitrogen made during the NASA Subsonic Assessment, Ozone and Nitrogen Oxide Experiment (SONEX) afforded an opportunity to study the coupling

Photolysis of surface O3 and production potential of OH radicals in the atmosphere over the Tibetan Plateau

[1] With an area of 2.5 million km2 and an average altitude of about 4000 m above sea level, the Tibetan Plateau is the largest and highest plateau in the mid-latitudes of the Northern Hemisphere.

Removal of Stratospheric O3 by Radicals: In Situ Measurements of OH, HO2, NO, NO2, ClO, and BrO

Measurements of the concentrations of OH, HO2, ClO, BrO, NO, and NO2 demonstrate the predominance of odd-hydrogen and halogen free-radical catalysis in determining the rate of removal of ozone in the lower stratosphere during May 1993 and quantitatively demonstrates the coupling that exists between the radical families.

Are models of catalytic removal of O3 by HOx accurate? Constraints from in situ measurements of the OH to HO2 ratio

Measurements of the ratio OH/HO_2, NO, O_3, ClO, and BrO were obtained at altitudes from 15–20 km and latitudes from 15–60°N. A method is presented for interpreting these simultaneous in situ

A discussion of the chemistry of some minor constituents in the stratosphere and troposphere

A discussion is given of atmospheric reactions in the H2O−CH4−O2−O3−NOx system. In the lower troposphere such reactions may lead to significant production of ozone. Their role in the odd hydrogen

Reactive surface emissions of reduced sulfur gases can produce SO2 in the middle and upper troposphere at the levels of 80±30 pptv measured high over the remote oceans. We present simulations with a

Oxidation rates of trace gases in the troposphere depend on species-specific rate coefficients and are predominantly governed by the concentration of the hydroxyl radical (OH), the most important

The odd-hydrogen radicals OH and HO2 are central to most of the gas-phase chemical transformations that occur in the atmosphere. Of particular interest is the role that these species play in
