2 Department of Atmospheric, Oceanic and Space Sciences, the University of Michigan, Ann Arbor, Michigan,U.S.A ABSTRACT Ozone, CO, NO, NOy and SO2 were measured at a relatively remote site in Hong Kong (22° 13'N, ° 23'E, 60 m MSL) during the PEM-WEST B Experiment (February-March ).

"Global tropospheric experiment at the Hong Kong atmospheric chemistry measurement station": final report. The major activities of the Global Tropospheric Experiment at the Hong Kong Atmospheric Chemistry Measurement Station are presented for the period 1 January - 31 December Activities included data analysis, reduction, and archiving of atmospheric measurements and sampling.

Sampling included O3, CO, SO2, NO, TSP, RSP, and ozone column : Tao Wang and Mary Ann Carroll. Even well before this (e.g., ), Reg, along with four other members of a newly formed NASA tropospheric chemistry committee, was busy at work defining the foundation of GTE.

He and the rest of the committee convinced the earth sciences component of this organization that the future of atmospheric chemistry was in global field sampling campaigns.

The outcome is a concept for an integrated global observing system for tropospheric NO2 that comprises DOAS nadir satellite measurements and a set of latitudinally distributed mountain-site or clean-air FTIR stations.

1 Introduction The importance of NO2 in atmospheric chemistry had been described in the literature more than 25 years. Here we present measurements of nighttime nitrogen oxides, NO 3 and N 2 O 5, from a coastal mountaintop site in Hong Kong adjacent to the megacities of the Pearl River Delta region.

This is the first study of nighttime chemistry from a site within the residual layer in China. Through the coordination of the International Global Atmospheric Chemistry (IGAC) Program, the East Asia/North Pacific Regional Study (APARE) was initiated to study chemical processes and long range transport over the northwest Pacific ocean, and to estimate the magnitude of the human impact on the oceanic atmosphere over this region.

Introduction. The purpose of this paper is to report satellite-based measurements of tropospheric chemistry from the tropospheric emission spectrometer (TES), and the atmospheric chemistry experiment (ACE) with a primary focus on carbon monoxide (CO).

Acetic acid (CH 3 COOH) is one of the most abundant carboxylic acids in the troposphere. In the study, the tropospheric chemistry of CH 3 COOH is investigated using the 3‐D global chemistry transport model, STOCHEM‐CRI. The highest mixing ratios of surface CH 3 COOH are found in the tropics by as much as ppb in South America.

The model predicts the seasonality of CH 3 COOH reasonably Cited by: 3. With the discovery of the ozone layer in the stratosphere (Fowler and Strutt, ) surface ozone measurements continued in the first half of the 20 th century as an adjunct to explore atmospheric composition.

Introduction The NASA Global Tropospheric Experiment (GTE) is a program of aircraft-based experiments dedicated to improving our knowledge of global tropospheric chemistry and of its implications for the biosphere, climate, and stratosphere.

The program arose in the late 's and early 's to address science priorities established in a National Academy of Sciences study (NAS, ).

A major componentof the NASAprogram is the Global Tropospheric Experiment (GTE), which consists of a series of field experiments designed to (I) evaluate the capability of instrument techniques to measure.

GTE - Global Tropospheric Experiment GTE utilizes large, extensively instrumented aircraft as primary research tools. However, GTE also draws heavily upon satellite observations of meteorology, land use and atmospheric chemical species to aid in experiment design and in the scientific analyses of results obtained from aircraft and ground-based measurements.

Measurements of tropospheric ethene have been attempted on a large scale by using infrared solar occultation with satellite measurements of the Atmospheric Chemistry Experiment FT spectrometer.
