New expressions for the wavelength-dependent photolysis quantum yields of CH2O, Φj, are presented. They are based on combinations of functions of the type Ai/(1+exp[−(1/λ − 1/λ0i)/bi]). The parameters Ai, bi, and λ0i which have a physical mea

On the deuterium-salinity relationship in the Baltic Sea

Autor: D. H. Ehhalt

Publikováno v: Tellus A; Vol 21, No 3 (1969)

Two vertical deuterium profiles at the Bornholm Basin in the Baltic Sea are described. Both profiles show a uniform deuterium content from the surface down to about 40 m. At greater depths the deuterium content increases. Supplemented by measurements

MIPAS, the Michelson Interferometer for Passive Atmospheric Sounding, is a mid-infrared emission spectrometer which is part of the core payload of ENVISAT. It is a limb sounder, i.e. it scans across the horizon detecting atmospheric spectral radiance

Sources and sinks of atmospheric methane

Autor: U. Schmidt, D. H. Ehhalt

Publikováno v: Pure and Applied Geophysics PAGEOPH. 116:452-464

In 1972 average mixing ratio of methane in the troposphere was 1.41 ppm and 1.3 ppmv for the northern and southern hemisphere, respectively, which corresponds to a total amount of 4×1015 g of CH4 present in the atmosphere. Most is of recent biologic
