A lidar system based at the Haute‐Provence Observatory (44°N, 6°E) has been used to obtain night‐time density and temperature profiles in the altitude range 35‐70 km. If the lidar results are normalized to an in‐situ rocket sounding from 35 to 40 km, the lidar and rocket ...
Density altitude Density altitude is the altitude in the International Standard Atmosphere at which the air density would be equal to the actual air
Altitude Density and specific volume of air varies with elevation above sea level. Air - Density, Specific Weight and Thermal Expansion Coefficient vs. Temperature and Pressure Online calculator, figures and tables showing density, specific weight and thermal expansion coefficients of air at ...
atmosphere temperatureIn the altitude region between 52 and 117 km measurements of total density and temperature were performed by Pitot tubes, mass spectrometers and H-Lyman-伪 photometers. These data were obtained during the Western European Winter Anomaly Campaign 1975/76 under highly disturbed ...

Ionospheric ions (O + and H + ) and temperature (Ti) as precursory parameters to seismic activity have been analysed from year 1995 till 1998, using SROSS-C2 (average altitude range of 500km) satellite measurements for moderate magnitude earthquakes. The details of seismic events during this ...

The density of air is 0.00120 g/cm3 at 20°C and under atmospheric pressure of 101.325 kPa (i.e. at sea level). This atmospheric pressure changes with the weather conditions (lower pressure when rainy or snowy) and with the altitude (lower pressure at high altitude than at sea ...
