Contribution of water vapor dimers to clear sky absorption of solar radiation

Using recently derived-values of the water vapor dimer spectral absorption cross section we calculate the water vapor dimer contribution to the clear sky absorption of solar radiation. We consider the water dimer concentrations deduced from local equilibrium thermodynamics, and we account for the overlap of water vapor dimer and monomer absorption bands. We estimate that water vapor dimer contr...

Precipitable Water Vapor from Radar and 6.7 M Radiometer Comparison of Precipitable Water Vapor Observations by Spaceborne Radar Interferometry and Meteosat 6.7 M Radiometry

Satellite radar interferometry (InSAR) can be applied to study vertically integrated atmospheric refractivity variations with a spatial resolution of 20 m and an accuracy of 2 mm, irrespective of cloud cover or solar illumination. The data are derived from the diierence between the radar signal delay variations within the imaged area during two acquisitions with a temporal separation of one or ...

On the angular effect of residual clouds and aerosols in clear-sky infrared window radiance observations: Sensitivity analyses

[1] Accurate environmental satellite observations and calculations of top-of-atmosphere infrared (IR) spectral radiances are required for the accurate retrieval of environmental data records (EDRs), including atmospheric vertical temperature and moisture profiles. For this reason it is important that systematic differences between observations and calculations under well-characterized condition...

Cloud Microphysical Properties Retrieved from Rapid-Sample AERI Data

The Atmospheric Emitted Radiance Interferometer (AERI) measures downwelling infrared radiance from 550-3000 cm (18.2 – 3.3 μm) at high-spectral-resolution (~ 1 cm) (Knuteson et al. 2004). The original temporal sampling strategy (a 3-min average of sky radiance every 8 min) was chosen to optimize the signal-to-noise in the observations for clear sky applications. Clear-sky AERI observations have...
