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...
for example, conceived for correcting laboratory tests, using: U=Uo*K, where U and Uoare the dielectric strengths at high altitude and at standard atmospheric conditions respectively and K is the air density correction factor given by K=δmwith δ being...
The Borborema Plateau (central region of Pernambuco, Paraiba and Rio Grande do Norte) is a topographic barrier, with altitude up to 1200 m (Fig. 1). When the east/southeast trade winds hit the elevated terrain, this airflow ascends, causing the development of thunderstorms and favoring ...
This means the air pressure is directly related to the altitude. As gases and liquids are fluids, the following information must be considered: Gas (e.g. air), is a compressible fluid, which changes its volume at different pressures. Liquids (e.g. water), are considered incompress...

Bearing in mind that the electron density increases with the D-region altitude, i.e., the upper D-region provides the dominant contribution to TECDD, we assume that the flux representing the X-radiation (ϕ) is the flux recorded by the GOES channel B. The data recorded through this ...
The necessary parameters included the average altitude (HE = 40 m), the latitude (φ = 34.24°), and the relative air humidity (RH) of the study area, as shown in Equations (12) and (13) [46]. In the mid-latitude summer, the linear relationship between Tair_e and Tair is shown ...
Achieving this goal is becoming increasingly easier, as the new sensor and data collection infrastructure supports better access to the context properties (speed, acceleration, direction, curvature, barometric pressure, humidity, altitude, etc.) of movement [62]. There are several issues worthy of ...
Moreover, winter tropopause is at a greater pressure and lower altitude, which is being brought to a level closer to model level, therefore calculations using our BEHR-HK products capture it better. 6. Discussion In this section, we compare the satellite retrieval algorithms with available raw ...
