Ice Concentration Retrieval in Stratiform Mixed-Phase Clouds Using Cloud Radar Measurements

Jul 21, 2014 Funded By: ARM ASR

The production of ice particles in clouds has significant impacts on their precipitation efficiency, lifetime, and radiative properties. Recent observations reveal that mixed-phase clouds, which contain both liquid droplets and ice particles, have a large global coverage and are the dominant cloud type over polar regions. The ice number concentrations (Ni) in these clouds are [...]

Precipitation Estimation from the ARM Distributed Radar Network

Jun 20, 2014 Funded By: ARM ASR

Recently, the US Department of Energy's (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility outfitted its fixed and mobile sites with scanning dual-polarized X/C-band weather radars. These systems are designed for improved observation of cloud and precipitation evolution, dynamic and microphysical processes and longer-term precipitation trends. An initial priority has been the development of a [...]

Comparison of Mixed-layer Heights from Airborne HSRL and WRF-Chem During CARES

Jun 05, 2014 Funded By: ARM ASR

The NASA Langley Research Center (LaRC) airborne High Spectral Resolution Lidar (HSRL) was deployed to California on board the NASA LaRC B-200 aircraft to aid in characterizing aerosol properties during the California Research at the Nexus of Air Quality and Climate Change (CalNex) and Carbonaceous Aerosol and Radiative Effects Study (CARES) field campaigns in May [...]

Accuracy of GFS and ECMWF Hurricane Sandy Track Forecasts Dependent on Cumulus Parameterization

May 19, 2014 Funded By: ASR

Hurricane Sandy (2012) was an extremely damaging late-season storm that significantly impacted much of the northeastern United States. Aside from the damage to life and property, Hurricane Sandy was also noteworthy for its large forecast track differences very early in its life cycle. Roughly one week before landfall, the European Center for Medium-range Weather Forecasting [...]

The Emergence of Open Source Software for the Weather Radar Community

May 15, 2014 Funded By: ARM ASR

Since the emergence of weather radar technology in the 1940s, research has sought to tap the full potential of weather radar observations. During the digital age, improvements in radar technology have been closely linked to advancements in computer science and software engineering. Making use of modern radars is not possible without software. Open Source Software [...]
