The Standard AP8 and AE8 models for predicting trapped proton and electron environments have been compared with several sets of flight data to evaluate model uncertainties. Model comparisons are made with flux and dose measurements made on various U.S. low-Earth orbit satellites (APEX, CRRES, DMSP,LDEF, NOAA) and Space Shuttle flights, on Russian satellites (Photon-8, Cosmos-1887, Cosmos-2044),and on the Russian Mir Space Station. This report gives the details of the model-data comparisons--summary results in terms of empirical model uncertainty factors that can be applied for spacecraft design applications are given in a combination report. The result of model-model comparisons are also presented from standard AP8 and AE8 model predictions compared with the European SpaceAgency versions of AP8 and AE8 and with Russian-trapped radiation models
