The comparison of the density data by the models and the satellite data shows that, under the condition of equal confidence coefficient, the error bands of all three models increase with increasing altitude. For high confidence coefficient(95%), the error band of NRLMSISE-00 and WACCM at 80 ...
The exponential decrease in density with altitude results in most absorption occurring at the tangent altitude, or the altitude of closest approach of the line of sight to the solid Earth (see Chapter 5). A recent review of occultation techniques and their use in studying the atmospheres of ...
the density decreases with altitude by the factoreover the distanceh. The lower boundary of the atmosphere is located atz = 0 and can represent either solid ground, ocean surface, or ice. Because of the large density contrast with the air, the boundary...
The purpose of the Atmospheric Density Specification (ADS) mission (AFGL-705) is to generate a coordinated and comprehensive global set of lower thermospheric state variables (density, temperature, and wind) in the altitude range 100 - 300 kilometers. This data set will be analyzed by a team...

An 'Atmospheric Window' refers to specific wavelength ranges in the solar reflective spectrum where the Earth's atmosphere has minimal gas absorption effects, allowing for accurate data collection by multispectral sensors. AI generated definition based on:Hyperspectral Remote Sensing,2020 ...
The ‘line shape function’ b(ν,νul), normalized such that ∫bν,νuldν=1, gives the probability density that the transition is observed at frequency ν rather than the nominal νul=Eu−El/h. Atmospheric microwave line shapes are dominated by collision (pressure) broadening at lower ...
