Based on geography characteristic of our country and the analytic and statistic results of weather elements
the difference of atmospheric conditions between our country and Soviet Russia can be obtained. At the same time
their different influence on the flight trajectory of projectile has been validated by simulation
which shows the necessity of revising the standard atmospheric conditions of our country. A preliminary plan of standard atmospheric conditions of our country is put forward
which identify the near earth criterion with Soviet Russia′s
and virtual temperature alters with height on condition that y≤16 km
