Abstract: The purpose of this paper is to present a working model for the diffusion of gases from multiple sources in an urban area. Since 24-hr sulfur dioxide measurements were made at 32 sampling stations in Nashville, Tenn., ...

Abstract: A new approach to retrieve microphysical properties from mixed-phase Arctic clouds is presented. This mixed-phase cloud property retrieval algorithm (MIXCRA) retrieves cloud optical depth, ice fraction, and the effective ...

Abstract: Three methods to calculate wind direction standard deviation are evaluated. Although eight hours of wind data show no significant differences between the methods, synthetically generated data having standard deviations ...

Abstract: Radiative transfer models used in processing TIROS-N sounder data via Physical retrieval schemes do not explicitly account for changes in CO2 mixing ratio. However, CO2 mixing ratios have increased by approximately 30 ppmv ...

Abstract: The effect of changes in the mixing ratio of C02 on the uniformly mixed gases component of the TIROS-N Observational Vertical Sounder radiances in High-Resolution Infrared Sounder (HIRS) channels is examined using a ...

Abstract: The suggestions of Pasquill as set forth in his landmark 1961 Meteorological Magazine paper are briefly reviewed. These methods are viewed from the perspective of the requirements placed upon air agencies after the passage ...

Abstract: he Atmospheric Emitted Radiance Interferometer (AERI) observes spectrally resolved downwelling radiance emitted by the atmosphere in the infrared portion of the electromagnetic spectrum. Profiles of temperature and water ...

Abstract: Two independent ground-based passive remote sensing methods are used to retrieve lower-tropospheric temperature and humidity profiles in clear-sky cases. A simulation study for two distinctly different climatic zones is ...

Abstract: The determination of the horizontal attitude of a balloon-borne, infrared, limb-scanning radiometer is discussed. In particular, the relationship between scan-angle, as measured by the instrument, and the tangent height ...

Abstract: Prior to the Atmospheric Radiation Measurement program?s first water vapor intensive observation period (WVIOP) at the Cloud and Radiation Testbed site near Lamont, Oklahoma, an automated 24-h Raman lidar was delivered to ...
