If this coniferous forest can be considered representative, we estimate a contribution of temperate coniferous forest soils to the global N.O budget of 1 Tg y.. For NO, mean annual fluxes from temperate coniferous forest soils were estimated to be in the range of 0.5–24 µg

Biogeochemical Cycles of Carbon on a Hierarchy of Time Scalesc carbon dioxide on all time scales. Particular problems with restricted time scales can be analyzed in terms of a subset of the total system. Observations that illustrate interactions on different levels of the hierarchy include the seasonal change of carbon dioxide partial pressure, the glacial to

Ice Core Records as a Key to Understanding the History of Atmospheric Trace Gasesated with global climatic changes showing strongly depleted concentrations (by up to about a factor of 2 in the case of CH.) during the full glacial conditions relative to interglacial periods. The gas records obtained from ice cores can be interpreted, at least qualitatively, in terms of flux chang

Late Jurassic Paleoclimate of Pangea Based on Results from a General Circulation Modelfrom a simulation using 1120 ppm CO., four times the preindustrial level, produce a paleoclimate that fits the geologic record. Sea ice is restricted to the high latitudes, making landfall only in restricted areas. The trade winds bring heavy seasonal rainfall to eastern Gondwana and to the Tethys S

A Time-Dependent Two-Dimensional-Model Study of the Trend in Atmospheric Methaneations of tropospheric OH, caused mostly by increasing abundances of CO, with the remaining 60% due to increasing emissions of CH.. However, our calculations only include the direct coupling between CO, CH., and OH. Uncertainties due to the impact of other factors, such as increases in tropospheric
