Global Atmospheric Research Program

Specific features of the Arctic atmosphere, such as Arctic Haze and extended cloudiness and radiation, were studied during the the First GARP (Global Atmospheric Research Program) Global Experiment, FGGE (Kondratyev, 1999a, b).

The key species in tropospheric chemistry is believed to be the free radical species, OH. It is this species that is hypothesized to initiate the oxidation of many of the reduced compounds emitted into the atmosphere and thus has a major role in controlling the trace gas composition of the atmosphere. While photochemical models predict OH to be present in the lower atmosphere, this prediction has yet to be confirmed by direct atmospheric measurements. A major goal of any research program in global tropospheric chemistry should be a test of photochemical theory for OH. This will require not only measurements of OH levels in the atmosphere but also simultaneous measurements of the concentrations of the species which control OH. Concurrently with the test of the OH photochemical theory, more detailed studies of tropospheric chemical transformation and reactions should be prepared. 

Another important goal of a tropospheric chemistry research program should be to establish a global air sampling network to characterize the distribution of atmospheric compounds today. In order to determine if the tropospheric composition is changing, a commitment must be made to maintain this network into the 21st century. The interchange of... 

The Bucharest station (part of the Global Atmospheric Watch (GAW) Ozone Network as "associated station") fulfils the interaction with other programs and activities. Romania is a permanent participant in the WMO/GAW - GOOS and some European Union Programmes concerning the monitoring of the ozone layer. The research orientation of lAMAS is also related to a development (in the NIMH) of an operational Air Pollution Forecast System. Its goal is to produce 3-day air pollution forecasts of the most important air pollution species on different...
