Abstract : This report describes the PRISM 1.7e algorithm for data assimilation and near real time global ionospheric specification. It also describes the basis for PRISM climatology, including descriptions of the three physical models which were parametrized to produce it, the parameterization method itself, as well as the semi-analytic representation used to produce a compact representation of the climatology. It includes appendices containing the I/O specification for PRISM and internal memoranda describing the changes for each version from 1.5 through 1.7e.
