Central Radio Propagation Laboratory Ionospheric Predictions Based on Numerical Methods of Mapping (formerly CRPL-D series) is described. The Gallet -Jones method of numerical mapping, which is the basis of these predictions, is briefly described. Use of an electronic computer for applying the predictions is recommended. Graphical F2-layer prediction maps, derived from the numerical predictions, are described in detail. Instructions and auxiliary material are provided for applying the graphical map predictions by manual methods. Some limitations of the predictions and aspects of ionospheric radio propagation are discussed briefly.

Keywords: maximum usable frequency (MUF); ionospheric propagation; prediction methods; numerical maps; ionospheric predictions
