Abstract: The effect of vertical inhomogeneities of atmospheric attenuators upon determinations of air mass and upon Langley plot determinations of the extra-atmospheric solar irradiance is examined and found to be significant, ...

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: Vertical profiles of aerosol extinction and backscatter in the troposphere are obtained from multizenith angle lidar measurements. A direct slant path solution was found to be not possible due to horizontal inhomogeneity ...

Abstract: An automated multichannel solar radiometer has been designed and fabricated by the Atmospheric Remote Sensing Laboratory at The University of Arizona. The automated radiometer has 10 separate silicon-photodiode-based ...

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: Particulate size and height distributions, complex refractive index and mass loading have been measured and inferred from direct aircraft and indirect lidar-solar radiometer observations made during a unique joint experiment ...

Abstract: The Lidar In-Space Technology Experiment (LITE) is being developed by NASA/Langley Research Center for a series of flights on the space shuttle beginning in 1994. Employing a three-wave-length Nd:YAG laser and a 1-m-diameter ...
