“…Atmospheric aerosols consist of primary (sea spray, crustal material, smoke, and organic matter) and secondary (sulphates, nitrates, ammonia, volatile organic compounds) components (Kondratyev et al, 2005). Their presence reduces air quality, affecting human health, visibility and life in the whole biosphere (Pöschl, 2005).…”

Atmospheric aerosols impact air quality and global climate. Space based measurements are the best way to observe their spatial and temporal distributions, and can also be used to gain better understanding of their chemical, physical and optical properties. Aerosol composition is the key parameter affecting the refractive index, which determines how much radiation is scattered and absorbed. Composition of aerosols is unfortunately not measured by state of the art satellite remote sounders. Here we use high resolution infrared measurements for aerosol type differentiation, exploiting, in that part of spectrum, the dependency of their refractive index on wavelength. We review existing detection methods and present a unified detection method based on linear discrimination analysis. We demonstrate this method on measurements of the Infrared Atmospheric Sounding Interferometer (IASI) and five different aerosol types, namely volcanic ash, windblown sand, sulfuric acid droplets, ammonium sulfate and smoke particles. We compare these with traditional MODIS AOD measurements. The detection of the last three types is unprecedented in the infrared in nadir mode, but is very promising, especially for sulfuric acid droplets which are detected in the lower troposphere and up to 6 months after injection in the upper troposphere/lower stratosphere

“…This development can be expected around nodes in the environment, where advantageous circumstances for the growth of one mode (AB, say) give way to another (AB'). The appearance of ABAB' forms at a node can recapitulate the same modified LV equations (7)(8) as for the original AB combination, with α now standing for AB and β for AB'. Note then the early and essential appearance of recapitulation as a characteristic of living processes.…”

“…There may be other energy sources, but the location of living matter about the Earth and the central role of photosynthesis within biology [7] push solar flux as the most likely main driver. A reasonable estimate for the total energy driving the entire biosphere is ~10 12 kW [8]. The solar flux thus has enough power to drive this 'engine': the problem is about how it works.…”

“…It is generally recognized today that the complete understanding of the CO 2 contribution in the formation of the atmospheric greenhouse effect presupposes a thorough examination of the biogeochemical dynamics of the carbon cycle Kondratyev et al, 2004;Krapivin and Varotsos, 2008;Amann et al, 2011). In the current literature a lot of schematic pathways of carbon cycle are considered in the form of global CO 2 changes.…”

The issues of air pollution are inextricably linked to the mechanisms underlying the physicochemical functioning of the biosphere which together with the atmosphere, the cryosphere, the lithosphere, and the hydrosphere constitute the climate system. We herewith present a review of the achievements and unresolved problems concerning the modeling of the biochemical cycles of basic chemicals of the climate system, such as carbon and nitrogen. Although the achievements in this area can roughly describe the carbon and nitrogen cycles, serious problems still remain associated with the accuracy and precision of the processes and assessments employed in the relevant modeling.
