### **Abstract**

The global numerical first principle 3D model of the upper atmosphere (UAM) for the heights 60–100,000 km is presented. The physical continuity, motion, heat balance and electric potential equations for the neutral, ion and electron gases and their numerical solution method are described. The numerical grids, spatial and time integration steps are given together with the boundary and initial conditions and inputs. Testing and obtained geophysical results are given for many observed situations at various levels of solar, geomagnetic and seismic activity.

**Keywords:** global numerical model, UAM, equations, solution method, grid, integration steps, input, output, upper atmosphere, thermosphere, ionosphere, plasmasphere, magnetosphere, space weather, solar and geomagnetic activity
