The impact of vertical variations of cloud mircrophysics and drizzle on the angular anisotropic behavior of weighted cloud droplet effective radius
The effective radius (Re) of the cloud droplet size distribution is an Essential Climate Variable identified by the Global Climate Observing System for its important role in energy and water cycle studies. It is retrieved simultaneously with optical depth (τ) from passive satellite imagers, like …

Analysis of Slug Tests to Determine Hydraulic Conductivity of Vertical Cutoff Walls
… such as the Bouwer and Rice method, a modified effective radius, and a reduction factor. Both of these new methods provide a more rigorous and accurate estimate of hydraulic conductivity compared to previously available methods. Both new methods are practical and easy to use.

The calculation of cloud parameters from AVHRR data
… observation/illumination geometry and the effective radius of the cloud drop-distribution. The variation in drop-size is contained in an ensemble of modified-Gamma distributions whose effective radius varies from 1 to 30 μm with a fixed dispersion of 0.25. A technique is established which …

Sources of localized waves
… pulses from dynamic apertures, or apertures the effective radius of which is varied with time. Ideal L W pulses cannot be realized because they require infinite time excitation. However, in the case of finite L W pulses, the aperture of excitation is finite and is varied from a time - T to T. We …

Predicting strength of wood beams with tension end notches
… such as beam height, fractional notch depth, radius and notch location. The effect of span-to-depth ratio is implicitly incorporated in the formulation of the model. Notched beam strength is represented by a material parameter, K, which was found to be related to specific gravity. A simple …

Characteristics of Yellow Sea Fog Under Varying Aerosol Conditions
… are related to both smaller ER (Droplet Effective Radius) and higher CTH (Cloud Top Height). However, for the cases where fog is relatively thinner with many zero values in CTH, the larger COT is related to both smaller ER and CTH. For the fog cases where AOD is dominated by smoke (e.g. …
