The variation of components in the radiation balance over different fynbos vegitation types
… consider the vegetation at the sites where the radiation measurements were carried out in order to determine whether similar vegetation structural types have similar radiation regimes. In order to do this, six sites were selected in the Cape of Good Hope Nature Reserve. At each site the …

Implications of the Dense City Centre to Surface-Atmosphere Exchanges
… in London. The focus is on the controls on radiation, anthropogenic heat and the turbulent latent and sensible heat fluxes. The impact of the composition and three-dimensional structure of the urban surface, plus the associated anthropogenic activities, are investigated using remote sensing …

Ambient Observations of Aerosols, Novel Aerosol Structures, And Their Engineering Applications
… the Earth by altering the Earth's delicate radiation balance, human health, and visibility. In particular, black carbon particulate matter remains the key driver in positive radiative forcing (i.e., warming) due to aerosols. Produced from the incomplete combustion of hydrocarbons, these …

Assessment of Convectively Generated Tropical Cirrus in Global Storm-Resolving Models
… the climate by altering the top-of-atmosphere radiation balance and stratospheric water vapor budget. These cirrus are often associated with deep convection, which global climate models must parameterize and struggle to accurately simulate. By comparing high- resolution global models from the …

Atmospheric radiative transfer in multiple scattering conditions. Application to NWP models.
… important contribution to the Earth-atmosphere radiation balance. The work has been focussed on the development of the RT model LBLMS. The model, widely tested in the infra-red spectral range, has been extended to the short wave spectrum and it has been used in comparison with airborne and …

Modellierung von Flächendatensätzen der Oberflächentemperatur, Strahlungsbilanz und Kaltluftproduktion in windschwachen Strahlungsnächten
… spatial distribution of surface temperature, net radiation and cold air production obtained on cloudless nights. The method is tested on the region of the Regio-Klima-Projekt (REKLIP) which covers the Upper Rhine Valley from Basle to Karlsruhe and the adjacent mountains. <br>The approach for this …

Feedback mechanism in the oceanic carbon cycle
… on the atmosphere-ocean system through the radiation balance. The model reveals two feedback mechanisms, the global warming feedback and the thermohaline pCO 2 feedback. The thermohaline pCO2 feedback has three sub-components, which are the biological pump feedback, the outgassing feedback …

Genomic, transcriptomic, and metagenomic approaches for detecting fungal plant pathogens and investigating the molecular basis of fungal ice nucleation activity
… in clouds, which in turn affects Earth's radiation balance and the intensity and frequency of precipitation. A few fungal species can produce ice nucleating particles (INPs) that cause ice formation at temperatures ≥ –10°C and they may be present in clouds. Two such fungal genera are …

Microphysical retrieval of non-spherical aerosol particles using regularized inversion of multi-wavelength lidar data
… uncertainty in climate projections. Earth’s radiation balance is altered by aerosols depending on their size, morphology and chemical composition. Competing effects in the atmosphere can be further studied by investigating the evolution of aerosol microphysical properties, which are the focus …

Auswirkungen von Änderungen der Landnutzung auf das lokale Klima in Räumen mit unterschiedlichem Relief : der nächtliche Strahlungshaushalt historischer Landnutzungsmuster im Bereich südlicher Oberrhein, Schwarzwald und Baar
Die vorliegende Dissertation ist eingebettet in das interdisziplinär ausgerichtete Forschungsprogramm des DFG-Graduiertenkollegs "Gegenwartsbezogene Landschaftsgenese" (692/1) und liefert diesbezüglich einen Beitrag zur zeitübergreifenden Erforschung der Wechselwirkung zwischen Mensch und Umwelt …

Uncertainties in space-based estimates of clouds and precipitation: implications for deriving global diabatic heating
… energy transport required to establish a global balance. Clouds and precipitation play an integral role in this exchange, enhancing reflection of solar radiation to space, trapping thermal emission from the surface, and providing a mechanism for the direct transfer of energy to the atmosphere …

Temporal assessment of volatile organic compounds at a site with high atmospheric variability in the North–West Province
… for the formation of ozone (O3) during solar radiation initiated reactions in the presence of NOx. Tropospheric O3 is considered a pollutant, with negative impacts on human health, ecosystems and food security. O3 is also a short-lived greenhouse gas. Through reactions with radical species, …
