Abstract. Global warming is amplified in the Arctic. However, numerical models struggle to represent key processes that determine Arctic weather and climate. To collect data help constrain models, HALO–(𝒜𝒞)3 aircraft campaign was conducted over Norwegian Greenland seas, Fram Strait, central Ocean March April 2022. The focused on one specific challenge posed by namely reasonable representation of transformations air masses during their meridional transport into out via northward moist-...
Abstract. The spectrometer of the Munich Aerosol Cloud Scanner (specMACS) is a high-spatial-resolution hyperspectral and polarized imaging system. It operated from nadir-looking perspective aboard German High Altitude LOng range (HALO) research aircraft mainly used for remote sensing clouds. In 2019, its two line cameras, which are sensitive to wavelength between 400 2500 nm, were complemented by 2D RGB polarization-resolving cameras. cameras have large field view allow multi-angle...
Abstract. The global warming is amplified in the Arctic. To collect data that help to constrain weather and climate models, which often do not realistically represent enhanced Arctic warming, HALO-(AC)³ aircraft campaign was conducted March April 2022 over Norwegian Greenland Seas, Fram Strait, central Ocean. Observations were made areas of open ocean, marginal sea ice zone, ice. Two low-flying one long-range, high-altitude research have been employed. Whenever possible, three flown...
Abstract. The HALO–(𝒜𝒞)3 aircraft campaign was carried out in March and April 2022 over the Norwegian Greenland seas, Fram Strait, central Arctic Ocean. Three research – High Altitude Long Range Research Aircraft (HALO), Polar 5, 6 performed 54 partly coordinated flights on 23 flight days areas of open ocean, marginal sea ice zone (MIZ), ice. general objective to quantify evolution air mass properties during moist warm-air intrusions (WAIs) cold-air outbreaks (CAOs). To obtain a...
Near-surface winds are a key component for the coupling of atmosphere- ocean system. Convergence and divergence patterns can be inferred from measurements surface wind vector, enabling characterization meso- synoptic-scale atmospheric dynamics. Observations over remote areas, such as Atlantic ocean, mostly limited to satellites buoys. Geostationary derive data primarily cloud tracking thus do not measure winds. In contrast, polar-orbiting provide predominantly using active sensing...
Abstract. The cloud droplet size distribution is often described by a gamma defined the effective radius and variance. directly related to cloud's optical thickness, which influences radiative properties of cloud. variance affects, among other things, evolution precipitation. Both parameters can be retrieved from measurements cloudbow. cloudbow (or rainbow) an phenomenon that forms due single scattering radiation liquid droplets at edge. polarized radiance crucially depends on distribution....

A nonmagnetically modified graphene was employed as the adsorbent in dispersive solid-phase extraction (d-SPE) for isolation of permethrin from urine samples that were further analyzed by HPLC/UV method. The following four key factors influencing efficacy studied: 1. suspension volume, 2. adsorption time, 3. desorbent (acetonitrile) and 4. desorption time. Under optimized conditions d-SPE (graphene) procedure main validation parameters analytical method determined follows: recovery (%) 71.2,...
We present a method to retrieve cloud thermodynamic phase from multi-angle polarimetric and spectral imaging. Spectral absorption differences between water ice in the near infrared are commonly used discriminate liquid, mixed, clouds. For example, slope 1500 1700 nm increases with decreasing liquid fraction. These methods very sensitive small amounts of On other hand, polarization signal clouds shows different features depending on phase. The cloudbow is formed by single scattering droplets....
We present novel remote sensing observations of cloud droplet size distributions retrieved from polarimetric the wide-field airborne imaging system specMACS. The measurements were collected during EUREC4A field campaign which took place in January and February 2020 trade wind region east Barbados. focus on cloudbow is an optical phenomenon that results single scattering sunlight by liquid droplets close to top. signal strongly depends distribution. By fitting model simulations (stored a...
Funf Studierende des Masterstudiengangs Gender Studies an der Ruhr-Universitat Bochum geben Auskunft uber das, was sie geschlechterpolitisch beschaftigt und dazu bewogen hat, sich fur diese Disziplin zu entscheiden sowie diesen Text verfassen. Im Vorfeld Artikels wurde eifrig gemailt beisammen gesessen, Gedanken ausgetauscht geschrieben. Dabei herausgekommen ist eine etwas andere Innenperspektive von Studierenden Geschlechterforschung.
<rcd:p>Die längerfristige Entwicklung des Verkehrshandelns ist in den meisten Ländern mangels historischer Daten nur wenig erforscht. Für Deutschland liegen erst seit 1976 (West) bzw. 1972 (Ost) belastbare vor. Die gravierenden Veränderungen der Motorisierung, Stadtstrukturen, Verkehrsinfrastrukturen und -angebote im letzten halben Jahrhundert lassen sich an individuellen Mobilitätsbiografien Menschen ablesen.
