It is with regret that we inform you that Ed Andreas passed away on 30 September 2015. We will miss him for his original and careful scientific thinking. He was a kind person and a classic gentlemen in all regards. If you need to contact someone at NWRA, please email Joan Oltman-Shay, President of NWRA at j.oltman.shay@nwra.com or call 425 556 9055 x0.

Research interests: Atmospheric Sciences. The Arctic Oscillation, stratosphere-troposphere coupling, and propagation of planetary-scale waves in the troposphere and stratosphere.

Research interests: Solar physics, local helioseismology, solar interior.

Research interests: Inertia-gravity waves. Geophysical turbulence. Interaction between balanced and unbalanced motions. Mixed layer dynamics.

Research interests: Remote sensing of atmospheric gases and radiation from satellites. Radiative forcing of climate by greenhouse gases, cirrus clouds and relative humidity, detection of new airglow emissions, absorption of solar NIR by precipitating clouds.

Research interests: Research focus on Mesosphere and Lower Thermosphere (MLT) studies including modeling, simulation, and data fusion using Incoherent Scatter Radar (ISR) and Lidar. Interests include collisional plasma processes in the E-Region of the Ionosphere as well as meteoric smoke measurements and their relation to the Micrometeoric Input Function (MIF).

Research interests: Near-Earth Space Science: ionospheric physics (satellite experiments & radiowave tomographic imaging) and radio propagation (scintillation observations & modeling).

Research interests: Ocean and Earth Sciences, Fundamental Fluid Mechanics. Turbulence, vortices, remote sensing.

Research interests: Studies of clouds, water vapor, and radiation in the tropical upper troposphere and lower stratosphere.

Research interests: Experience in data analysis, turbulence and mixed layer processes, and data-model comparison studies. Research projects ranging from studies of the near-shore coastal environment, to deep-sea hydrothermal vents, to sea-ice modeling and field projects in the Arctic, to aircraft wake vortices. Recent work has included the A380 wake separation study group and participation in the FAA's ReCat Phase I project to reduce aircraft wake separation.

Research interests: Computer modeling of hydrodynamic phenomena, including vortex evolution, internal wave propagation, and turbulent dissipation; validation of computer models by comparison of computer results with observational data; processing and visualization of scientific data; diversified computing experience: various micro, mini, main-frame, and super computer systems.

Research interests: Data acquisition systems, data analysis (time and frequency domain), industrial process control (stability analysis and hardware selection), analog/digital circuit design, electro-optical systems, microprocessor system design, heat-exchanger design.

Research interests: I am using the WRF model to study convectively induced gravity waves.

Research interests: I study the propagation of optical waves through turbulence in the atmospheric boundary layer, with a focus on developing statistical estimators for the remote retrieval of atmospheric variables such as the horizontal wind velocity.

Research interests: Research areas: Tsunami dynamics; numerical modeling; time-series analysis
