Minimizing Instrumental Broadening of the Drop Size Distribution with the M-Fast-FSSP
Publisher: American Meteorological Society
Abstract: A modified version of the Fast-FSSP (the so-called M-Fast-FSSP) is introduced. It allows minimization of the instrumental broadening of measured cloud drop size distributions caused by laser beam inhomogeneities. This is ...
Observations of Small-Scale Turbulence and Energy Dissipation Rates in the Cloudy Boundary Layer
Publisher: American Meteorological Society
Abstract: Tethered balloon?borne measurements with a resolution in the order of 10 cm in a cloudy boundary layer are presented. Two examples sampled under different conditions concerning the clouds' stage of life are discussed. The ...
An Airborne Spectral Albedometer with Active Horizontal Stabilization
Publisher: American Meteorological Society
Abstract: An airborne albedometer including a low-cost, precise, and fast sensor head horizontal stabilization system was developed to measure spectral down- and upward irradiances between 400- and 1000-nm wavelength. It is installed ...
Laboratory Studies of Scattering Properties of Polluted Cloud Droplets: Implications for FSSP Measurements
Publisher: American Meteorological Society
Abstract: Laboratory experiments were conducted in the Mainz vertical wind tunnel to study the effects of pollutants dissolved or suspended in cloud droplets on the droplet size measurements of a Forward Scattering Spectrometer Probe ...
Evaluation of ECMWF Radiation Scheme Using Aircraft Observations of Spectral Irradiance above Clouds
Publisher: American Meteorological Society
Abstract: A novel approach to compare airborne observations of solar spectral irradiances measured above clouds with along-track radiative transfer simulations (RTS) is presented. The irradiance measurements were obtained with the ...
A CCD Spectroradiometer for Ultraviolet Actinic Radiation Measurements
Publisher: American Meteorological Society
Abstract: A new spectroradiometer for spectral measurements of ultraviolet (UV) atmospheric radiation (290?400 nm) using a charge coupled device (CCD) as a detector is introduced. The instrument development is motivated by the need ...
Probing Finescale Dynamics and Microphysics of Clouds with Helicopter-Borne Measurements
Publisher: American Meteorological Society
Abstract: Helicopter-based measurements provide an opportunity for probing the finescale dynamics and microphysics of clouds simultaneously in space and time. Due to the low true air speed compared with research aircraft, a helicopter ...
The Second ARM Training and Science Application Event: Training the Next Generation of Atmospheric Scientists
Publisher: American Meteorological Society
