abstract = {Using data from the Combined Release and Radiation Effects Satellite (CRRES) plasma wave experiment, we present quadratic fits to the mean of the wave amplitude squared, , for lower and upper band chorus as a function of geomagnetic activity (Kp) and magnetic latitude (λ) for the midnight (21 MLT≤3), dawn (3 MLT≤9), and postnoon (12 MLT≤15) sectors and present an ad hoc model for the prenoon (9 MLT≤12) sector. The empirical models are valid for 4≤L≤7, |λ| 15° and Kp≤6 and quantify the dramatic difference in the latitudinal dependence of chorus as a function of local time and how that dependence varies with geomagnetic condition, critical parameters for calculating wave-induced electron scattering rates. Our results are generally consistent with previous studies, and our key contribution is the quantification of wave properties in a manner that is easily incorporated into global quasi-linear diffusion models.}
