摘要: On October 4 and 10, 1967, the composition of lower thermosphere above Salto di Quirra, Sardinia (40°N), was measured by mass spectrometers. N2, O2, O, Ar, He densities are presented. Compared with Cira 1965, N2 reach model values or higher a factor 1.3, O2 2 to 3, O 1.1 Ar 3 7. 1.5 3. Helium in diffusive equilibrium other constituents thermosphere.
