Scientific paper

We have developed a statistical model of precipitating electron fluxes based on 10 years of NOAA-12 Space Environment Monitor (SEM) data. For each hour of universal time, the electron spectral shape is defined for solar activity (using F10.7), geomagnetic activity (using Dst, Kp, and PC indices), invariant latitude (invariant latitudes equal to or > 40\deg in both hemispheres), and magnetic local time. The climatology includes the precipitating differential fluxes determined from the SEM high-energy integral detectors and its low-energy differential electrostatic analyzers. In addition to total global energy flux input, the spectral information contained in the model enables computations of ionization rate profiles and Hall and Pederson conductivities. Model output is provided to the community interactively via a website where the fluxes may be obtained both graphically and as ASCII files. Strengths and limitations of the model and its applicability for use within an operational environment are illustrated.
