Abstract: A method of determining precipitable water to within 10% from solar radiometer data has been developed. The method uses a modified Langley technique to obtain the water vapor optical depth, and a model developed at the ...

Abstract: A second-derivative smoothing technique, commonly used in inversion work, is applied to the problem of inferring total columnar ozone amounts and aerosol optical depths. The application is unique in that the unknowns (i.e., ...

Abstract: The use of a shortwave infrared (SWIR) spectroradiometer as a solar radiometer is presented. The radiometer collects 1024 channels of data over the spectral range of 1.1?2.5 ?m. The system was tested by applying the Langley ...

Abstract: ighly accurate measurements of Earth?s thermal infrared and reflected solar radiation are required for detecting and predicting long-term climate change. Consideration is given to the concept of using the International ...

Abstract: Preflight and in-flight radiometric calibration plans are described for the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) that is a multispectral optical imager of high spatial resolution. It is ...

Abstract: te Absolute Radiance and Refractivity Observatory (CLARREO) mission will provide a calibration laboratory in orbit for the purpose of accurately measuring and attributing climate change. CLARREO measurements establish new ...
