Infrared radiation budget of the Harmattan haze

Infrared in situ observations of the West African Harmaltan Haze during the 1974 GATE field phase were conducted to determine the radiative properties of the tropospheric phenomenon and to develop a calculation model for radiative transfer through the haze. Radiometric observations of the dust haze were analyzed for haze infrared transmission. Infrared and tropospheric cooling rates are given together with the haze volume absorption rate.

Results of the US contribution to the joint US/USSR Bering Sea experiment

The atmospheric circulation which occurred during the Bering Sea Experiment, 15 February to 10 March 1973, in and around the experiment area is analyzed and related to the macroscale morphology and dynamics of the sea ice cover. The ice cover was very complex in structure, being made up of five ice types, and underwent strong dynamic activity. Synoptic analyses show that an optimum variety of weather situations occurred during the experiment: an initial strong anticyclonic period (6 days), followed by a period of strong cyclonic activity (6 days), followed by weak anticyclonic activity (3 days), and finally a period of weak cyclonic activity (4 days). The data of the mesoscale test areas observed on the four sea ice option flights, and ship weather, and drift data give a detailed description of mesoscale ice dynamics which correlates well with the macroscale view: anticyclonic activity advects the ice southward with strong ice divergence and a regular lead and polynya pattern; cyclonic activity advects the ice northward with ice convergence, or slight divergence, and a random lead and polynya pattern.

The Skylab concentrated atmospheric radiation project - An overview

An overview is presented of the Skylab Concentrated Atmospheric Radiation Project (SCARP), which was conducted to determine the accuracy and applicability of different models of radiation transfer through air masses of differing characteristics including varying amounts of wet and dry aerosols. Sites surveyed included onshore and offshore areas in the vicinity of Houston, Texas, the White Sands Missile Range in New Mexico, and Phoenix, Arizona, which provided a variety of warm, hot, dry, wet, clean, and dirty atmospheres. A typical exercise is described, and problems encountered during the experiment are discussed. It is noted that ten models of atmospheric scattering were utilized and that available data is being compared with the models.

Water vapor - Stratospheric injection by thunderstorms.

Infrared radiometric inference measurements of the mass of water vapor injected into the lower stratosphere and upper troposphere by a number of plains thunderstorms show an average threefold increase over the fair weather background mass of water vapor. These airborne measurements, made from the National Aeronautics and Space Administration Convair 990 jet laboratory, extended over a sample size much larger than that possible by balloon and other techniques.
