Hostetler

Description: Pacific Northwest National Laboratory, Richland, Washington, USA. The performance of the Weather Research and Forecasting regional model with chemistry (WRF-Chem) in simulating the spatial and temporal variations in aerosol mass, composition, and size over California is quantified using the extensive meteorological, trace gas, and aerosol measurements collected during the California Nexus of Air Quality and Climate Experiment (CalNex) and the Carbonaceo...

Long-term Variability of Dust Events in Iceland (1949–2011) : Volu...

By: O. Arnalds; H. Olafsson; P. Dagsson-waldhauserova

Description: Agricultural University of Iceland, Hvanneyri, Borgarnes, Iceland. The long-term frequency of atmospheric dust observations was investigated for the southern part of Iceland and interpreted together with earlier results obtained from northeastern (NE) Iceland (Dagsson-Waldhauserova et al., 2013). In total, over 34 dust days per year on average occurred in Iceland based on conventionally used synoptic codes for dust observations. However, frequent volcan...

Description: Centre for Research in Earth and Space Science, York University, Toronto, Ontario, Canada. We investigate the spatial and temporal distribution of hydrogen cyanide (HCN) in the upper troposphere through numerical simulations and comparison with observations from a space-based instrument. To perform the simulations, we used the Global Environmental Multiscale Air Quality model (GEM-AQ), which is based on the three-dimensional global multiscale model develo...

Dependence of Cloud Fraction and Cloud Top Height on Surface Tempe...

By: T. Deutschmann; S. Beirle; M. Grzegorski; T. Wagner; U. Platt

Description: MPI for Chemistry, Mainz, Germany. Cloud climate feedback constitutes the most important uncertainty in climate modelling, and currently even its sign is still unknown. In the recently published report of the intergovernmental panel on climate change (IPCC), from 20 climate models 6 showed a positive and 14 a negative cloud radiative feedback in a doubled CO2 scenario. The radiative budget of clouds has also been investigated by experimental ...

By: U. Platt; T. Wagner; E. Frins

Description: Instituto de Física, Facultad de Ingeniería, J. Herrera y Reissig 565, 11300 Montevideo, Uruguay. Topographic Target Light scattering – Differential Optical Absorption Spectroscopy (ToTaL-DOAS), also called Target-DOAS, is a novel experimental procedure to retrieve trace gas concentrations present in the low atmosphere. Scattered sunlight (diffuse or specular) reflected from natural or artificial targets located at different distances are analyzed to re...
