“…In recent years the remote sensing of the lower atmosphere has received considerable attention because of its importance in environmental monitoring. Particular emphasis has been placed on the retrieval of vertical temperature profiles from both microwave [Westwater, 1972;Westwater et al, 1975] and infrared [Wolk et al, 1967;Wang et al, 1975] ground-based radiometric observations. On the other hand, ground-based radiometry can also be a powerful tool for investigating the dynamics of the lower atmosphere.…”

Measurement of atmospheric brightness at different wavelengths in the infrared can give information about several parameters which characterize the vertical structure of the lower troposphere. In this paper some of the results obtained from a six‐month experiment carried out in 1975 are reported. The temperature profile has been retrieved from measurements of the average brightness at different elevation angles. In addition, measurements of both the variance and the low‐frequency spectrum of the radiometer output signal have been performed to obtain information on the intensity, scale length and spectra of temperature fluctuations. Particularly under stable tropospheric conditions, sharp periodicity of the radiometer signal has occasionally been observed, suggesting the occurrence of a periodic variation of the atmospheric parameters such as that associated with atmospheric waves. The data which have been collected appear to confirm the capability of ground‐based radiometry for the accurate and timely monitoring of the static and dynamic state of the lower troposphere.

The area of atmospheric optics has continued to flourish and burgeon. When we compiled this report four years ago we screened 400 titles for inclusion; this time the number increased to over 900 items, which were found chiefly by checking the contents lists of the five principal journals and utilizing abstracting journals for the rest. We retained about 750 in the bibliography, including a few reports that are available from the Clearinghouse for Scientific and Technical Information, Springfield, Virginia. We omitted most papers relating to the construction or calibration of equipment for atmospheric optical studies. Many papers appeared during this time period on the atmospheres of other planets; we included only papers closely related to the terrestrial atmosphere.

Artificial earth srttellites offer a unique opportunity t o exploit the possibility of deducing temperature profiles on a global scale from measurements of radiance in several narrow spectral intervals in A strongly absorbing band of an atmospheric gas whose mixture is uniform. In the earth's atmosphere the 4.3-micron and 15-micron bands of carbon dioxide and the 5-mm. band of oxygen may be used; only the 15-micron band is considered in detail, although the procedures are applicable to the other bands. The Woblem considered is the numerical solution of the integral form of the radiative transfer equation from measurements in a finite set of spectral intervals. It is shown that, by a suitable approximation of the Planck radiance, the radiative transfer equation can be reduced to an integral equation of the first kind. After a discussion of the kernel, which is associated with the transmittance of the gas, the equation is changed to a finite set of equations which is amenable to numerical solution. The solution is limited to about six pieces of information, which may be expressed as points along the vertical profile, or as coefficients of an expansion; the limitation in information is manifest in the transmittance curves for the several spectral intervals, the errors of measurement, and the approximations employed. However, even in this limited case the formal solution of the set of equations is unstable. I n this process the amount of smoothing remains small, so that the inherent properties of the temperature profile are not affected. Several possible 351 352
