Type:singleprecision floatingpoint scalar Turbulent kinetic energy dissipation rate This variable was calculated from the 30s standard deviation of the (approximately) 1s mean radar Doppler velocities and the horizontal winds from a forecast model using the technique of Bouniol et al. (2003, Proc. 31st AMS Conf. on Radar Meteorology, Seattle). Units:m^{2}s^{3}Type:singleprecision floatingpoint array Variable containing the random error in epsilon:epsilon_error Random error in dissipation rate, one standard deviation This variable is an estimate of the onestandarddeviation random error in turbulent kinetic energy dissipation rate. It was estimated from the error in model winds (assumed to be 1.5 m s1) and the random error in the measured standard deviation of Doppler velocity sigma_v (assumed to be sigma_v/sqrt(n), where n is the number of velocity samples used in the calculation, typically between 24 and 30).
