RISThe Behavior of Tropical Ozone During the Stratospheric Warming of March–April 1976
Publisher: American Meteorological Society
Abstract: The backscatter ultraviolet spectrometer on the Atmosphere Explorer-E satellite obtained ozone data for the upper stratosphere and lower mesosphere from an equatorial orbit near the time of the March?April 1976 stratospheric ...
The Attenuation of Sunlight by High-Latitude Clouds: Spectral Dependence and Its Physical Mechanisms
Publisher: American Meteorological Society
Abstract: Measurements of the ground-level solar irradiance from Palmer Station, Antarctica, and Ushuaia, Argentina, reveal a systematic wavelength dependence in the attenuation provided by cloudy skies. As wavelength increases from ...
Effective Photodissociation Cross Sections for Molecular Oxygen and Nitric Oxide in the Schumann-Runge Bands
Publisher: American Meteorological Society
Abstract: Simple polynomial representations of the altitude and zenith angle dependence of effective photodissociation cross sections for molecular oxygen and nitric oxide in the Schumann-Runge band region are presented. Longward ...
The Ultraviolet Radiation Environment of the Antarctic Peninsula: The Roles of Ozone and Cloud Cover
Publisher: American Meteorological Society
Abstract: The National Science Foundation scanning spectroradiometer at Palmer Station, Antarctica (64°46?S, 64°04?W) provides hourly ground-based measurements of solar ultraviolet (UV) irradiance at the, earth's surface. These ...
A Semiempirical Microscale Model of the Surface Energy Balance and Its Application to Two Urban Rooftops
Publisher: American Meteorological Society
Abstract: Individual structures within the same local-scale (102?104 m) environment may experience different microscale (<103 m) climates. Urban microclimate variations are often a result of site-specific features, including spatial ...
An Approach to the Detection of Long-Term Trends in Upper Stratospheric Ozone from Space
Publisher: American Meteorological Society
Abstract: A central problem in the detection of long-term trends in upper stratospheric ozone from orbiting remote sensors involves the separation of instrument drifts from true geophysical changes. Periodic flights of a Solar ...
The Transmission of Sunlight through Cloudy Skies: An Analysis Based on Standard Meteorological Information
Publisher: American Meteorological Society
Abstract: This work examines the use of standard meteorological information to describe the attenuation of sunlight associated with cloudy skies. Datasets consisting of broadband ultraviolet and total spectrally integrated solar ...
Tropospheric Influence on Solar Ultraviolet Radiation: The Role of Clouds
Publisher: American Meteorological Society
Abstract: Measurements obtained from several Robertson-Berger (RB) meters over the course of one year define the role of cloud cover in moderating biologically effective ultraviolet radiation at the Earth's surface. In an annual ...
Empirical Studies of Tropospheric Transmission in the Ultraviolet: Broadband Measurements
Publisher: American Meteorological Society
Abstract: This work examines the effects of absorption and scattering in the troposphere on solar ultraviolet radiation reaching the ground. A site was established in the city of Chicago for monitoring broadband ultraviolet irradiance, ...
