Book Description
A series of tables and charts is presented from which the atmospheric transmittance between any two points in the terrestrial atmosphere can be determined. This material is based on a set of five atmospheric models ranging from tropical to arctic and two aerosol models. A selected set of laser frequencies has been defined for which monochromatic transmittance values have been given. For low resolution transmittance predcition, a series of charts has been drawn providing the capability for predicting transmittance at a resolution of 20 wave-numbers. Separate sections are included on scattered solar radiation, infrared emission, refractive effects, and attenuation by cloud and fog. This third edition differs from the others in that the low resolution spectral curves for the uniformly mixed gases and in the short wavelength region for water vapor have been revised, providing some overall improvement in accuracy; and more importantly, an appendix has been added providing model data and equivalent sea level path data for the U.S. Standard Atmosphere, 1962.

Book Description
This book covers the fundamental principles of measuring oceans from space, and also contains state-of-the-art developments in data analysis and interpretation and in sensors. Completely new will be material covering advances in oceanography that have grown out of remote sensing, including some of the global applications of the data. The variety of applications of remotely sensed data to ocean science has grown significantly and new areas of science are emerging to exploit the gobal datasets being recovered by satellites, particularly in relation to climate and climate change, basin-scale, air-sea interaction processes (e.g. El Nino) and the modelling, forecasting and prediction of the ocean.

Book Description
SSH H2O data from the Defense Meteorological Satellite Program (DMSP) were received for analysis and evaluation. Approximately 70 measurements of upwelling radiation in the 8-sounder channels of the 18 to 30 micron rotational water vapor band have been compared with calculations for both clear and cloud contaminated conditions. The calculated radiances generally exceed the measured radiances in the clear column comparison. In the mean, the radiance comparison indicates a discrepancy less than 5 percent in the water vapor continuum band. This systematic discrepancy, by approximately a 4:1 ratio, is found in all the DMSP SSH H2O channels. These results are in agreement with McClatchey's 1976 results in his analysis of the DMSP 15 micron CO2 sounder channels. The data sets comparison were divided into three latitude belts, that is, Tropical, Mid-latitude and Arctic. In turn, the discrepancies between calculated and measured radiances appear to be latitudinally dependent. Smaller discrepancies are found in the Tropics and the larger discrepancies are found in the Arctic latitude belt. Also, it appears that the DMSP SSH H2O channels cannot discriminate between low cloud contamination and clear column conditions.
