Our electron precipitation climatology contributes to space weather research by providing a spectral description of atmospheric electron energy input. These electron energy spectra are used to generate atmospheric energy input, ionization rates, and height integrated Hall and Pederson conductivities. The climatology we present is from the Space Environment Monitor (SEM) data on board the NOAA-12 spacecraft. For each hour of UT, the electron spectral shape is defined for solar activity (using F10.7), geomagnetic activity (using Dst, Kp, and PC), invariant latitude (40 deg to 90 deg N and -40 deg to -90 deg S), and every hour of magnetic local time to form a climatology. Version 4 of our climatology includes a description of the precipitating differential number flux, unfolded from the integral high-energy telescopes of SEM and its lower-energy differential measurements. In total, the energy range covered by SEM is from 300 eV to 1 MeV. This climatology will be compared to previous models of precipitating electrons. Similarities and differences will be discussed.
