在1969年9月11日的日食期间，连续测量了Jicamara的电子温度、电子浓度和垂直等离子体漂移。对照测量于1969年9月13日进行。用一个求解含时电子-离子连续性方程的模型合成了观测到的电子浓度。对O+、NO+、O2+和N2+离子进行处理。以现实的方式考虑了与F区有关的物理和化学过程。在Jicamara上空300公里的中午，我们得到了O+产生率Q=290x10−3秒−1，损失系数β=1.94×10−4秒−1，原子氧标度高度H=59公里。该模型综合了在F2区观察到的所有大尺度特征。这种合成对Q和β同时减少30%不敏感
Continuous measurements of electron temperatures, electron concentrations, and vertical plasma drift were made at Jicamarca during the September 11, 1969, solar eclipse. Control measurements were made on September 13, 1969. Synthesis of the observed electron concentrations was made, using a model that solved the time-dependent electron-ion continuity equations. Ions O+, NO+, O2+, and N2+ were treated. Physical and chemical processes pertinent to the F region were considered in a realistic way. At noon, 300 km above Jicamarca, we obtained the values q = 290−3 sec−1 for the O+ production rate, β = 1.94 × 10−4 sec−1 for the loss coefficient, and H = 59 km for the atomic oxygen scale height. All large-scale features observed in the F2 region were synthesized by the model. This synthesis was not sensitive to a simultaneous 30% reduction of q and β
