Extraction of Atmospheric Signals from Radiance Measurements: Some Limitationsing of the error characteristics of the measurements and resulting products. Data error characteristics of the current generation of infrared and microwave sounders are discussed, and the resulting consequences for a physical retrieval algorithm demonstrated.

The Impact of the Initial Guess on the Accuracy of Satellite Retrievalseived by the current TIROS Operational Vertical Sounder (TOVS). One of the reasons such instruments are being considered is that numerical models used for weather prediction continue to improve, and as they improve they require increasingly more accurate observations. For example, the current TOVS s

We have developed a methodology for retrieving atmospheric and surface parameters under cloudy conditions using the AIRS/AMSU instruments. Since all fields-of-view are con

Retrieval of Cloud Parameters by Multiple High Spectral Resolution Observations in the Near-Infraredh the incoming solar radiation by scattering, and the outgoing thermal radiation by emission. Unfortunately, this combination of thermal and solar radiation has made it difficult to use observations in this region, and numerous investigators have avoided using daytime 3.7 μm observations (e.g. Stron

Spectral Variability of Light Scattering by Atmospheric Ice Crystalson is assumed to be random in space. Particle shapes are taken both from ice crystal classifications and from in-situ measurements made during the International Cirrus Experiment ICE, 1989. The spectral variability is discussed for hexagonal ice crystal columns in the range from 0.2 . to 16.0 . with

Detection of Polar Stratospheric Clouds with Next Generation IR SoundersThe method uses information from two satellite pixels and two spectral channels in the infrared. PSCs form and emit in very cold stratospheric environments (<195 K), and solutions of the bispectral method yield low temperatures in a range that clearly differ from those derived for a cold but cloudfr
