Abstract

A new Doppler radar turbulence detection algorithm, the NTDA, utilizes the radar reflectivity, radial velocity, and spectrum width data to perform quality control and produce eddy dissipation rate (EDR) estimates. The various EDR estimates, along with their associated confidences, are combined in a fuzzy-logic framework, with a single EDR and associated confidence produced for each radar measurement location. The B-757's 20 Hz vertical winds were used to estimate EDR, an atmospheric turbulence metric, using a single parameter maximum likelihood -5/3 model that assumes a von Karman energy spectrum form.
