Millimeter and sub-millimeter atmospheric performance at Dome C combining radiosoundings and ATM synthetic spectra

, 2012
The reliability of astronomical observations at millimeter and sub-millimeter wavelengths closely depends on a low vertical content of water vapor as well as on high atmospheric emission stability. Although Concordia station at Dome C (Antarctica) enjoys

Long‐Term High‐Resolution Radiosonde Measurements Reveal More Intensified and Frequent Turbulence at Cruising Altitude in China

Geophysical Research Letters
Turbulence is of great importance for aviation safety, but its long‐term trend in China remains unclear due to the scarcity of in‐situ measurements. Here the national‐scale assessment of turbulence dissipation rate (ε) at flight cruising altitude (200 ...

The effects of atmospheric refraction on the accuracy of laser ranging systems [PDF]

Correction formulas derived by Saastamoinen and Marini, and the ray traces through the refractivity profiles all assume a spherically symmetric refractivity profile.

Intercomparison of standard resolution and high resolution TOVS soundings with radiosonde, lidar, and surface temperature/humidity data [PDF]

One objective of the FIRE Cirrus IFO is to characterize relationships between cloud properties inferred from satellite observations at various scales to those obtained directly or inferred from very high resolution measurements.

Dropsondes and Radiosondes for Atmospheric Measurements

, 2012
Knowing the actual state of the atmosphere is the basis for any kind of weather forecast. The overall atmospheric condition is analyzed periodically using numerous ground station observations and radiosondes rising on a balloon and gathering the vertical profiles of pressure, temperature, humidity, wind speed and wind direction.
