Abstract: The near space parameter model (NSPM) is established since atmosphere parameters are required for development of near space, and the accuracy of the model is analyzed. Based on the calculation of relative accuracy, residual error, and standard deviation of NSPM, we find that the density and temperature results of the model are accord with the real time measurements, while the wind result can reproduce the mean wind profile well. Finally, we survey the seasonal variations of the parameters (density, temperature, pressure, meridional and zonal wind) in near space of China. The results indicate that they vary with different months and different places.
