This paper evaluates the feasibility of a method using a single hand-held infrared (IR) thermometer and a mini tower of wet and dry paper towels to psychometrically obtain surface layer temperature and moisture gradients and fluxes. Sling Psychromete

Optical turbulence, as determined by the widely accepted practice of profiling the temperature structure constant, CT2, via the measurement of ambient atmospheric temperature gradients, can be found to differ quite significantly when characterizing s

Knowledge of turbulence distribution along an experimental path can help in effective turbulence compensation and mitigation. Although scintillometers are traditionally used to measure the strength of turbulence, they provide a path-integrated measur

In this paper we describe methods to obtain bulk aerosol real and imaginary refractive index (RI) components from measurements of scattering and absorption. Results suggest existing databases of aerosol RI may be reasonable first estimates.

In this paper we compare results between three different turbulence measurement or estimation techniques. These approaches are: sonic anemometry; the MZA Path Resolved Optical Profiling System (PROPS); and a gradient technique using temperature and w

In this paper we describe a method to quantify visibility distance based on aerosol number concentration in the size spectrum 5nm to 2.5μm (PM2.5). This method allows complete automation of visibility assessments in weather observations.

Atmospheric turbulence profiles were estimated for a horizontal path based upon measurements made with a dual beacon Hartmann Turbulence Sensor (HTS) using simulation derived weighting functions. These results are compared to estimates made using a w
