RISAn Efficient and Accurate Algorithm for Computing Grid-Averaged Solar Fluxes for Horizontally Inhomogeneous Clouds
Publisher: American Meteorological Society
A Parameterization for the Absorption of Solar Radiation in the Earth's Atmosphere
Publisher: American Meteorological Society
Abstract: A method is described for rapidly computing the amount of solar energy absorbed at the earth's surface and in the atmosphere as a function of altitude. The method is a parametric treatment, but the form of the solution and ...
Global, Seasonal Cloud Variations from Satellite Radiance Measurements. Part II. Cloud Properties and Radiative Effects
Publisher: American Meteorological Society
Abstract: Global, daily, visible and infrared radiance measurements from the NOAA-5 Scanning Radiometer (SR) are analyzed for the months of January, April, July and October 1977 to infer cloud and surface radiative properties and ...
Global, Seasonal Cloud Variations from Satellite Radiance Measurements. Part I: Sensitivity of Analysis
Publisher: American Meteorological Society
Abstract: Global, daily, visible and infrared radiance measurements from the NOAA-5 Scanning Radiometer (SR) are analyzed for the months of January, April, July and October 1977 to infer cloud and surface radiative properties. In ...
Absorption within Inhomogeneous Clouds and Its Parameterization in General Circulation Models
Publisher: American Meteorological Society
Abstract: The effect on absorption in clouds of having an inhomogeneous distribution of droplets is shown to depend on whether one replaces a homogeneous cloud by an inhomogeneous cloud that has the same mean optical thickness, or ...
Near-Global Survey of Effective Droplet Radii in Liquid Water Clouds Using ISCCP Data
Publisher: American Meteorological Society
Abstract: A global survey of cloud particle size variations can provide crucial constraints on how cloud processes determine cloud liquid water contents and their variation with temperature, and further, may indicate the magnitude ...
Remote Sensing of Atmospheric Aerosols and Trace Gases by Means of Multifilter Rotating Shadowband Radiometer. Part II: Climatological Applications
Publisher: American Meteorological Society
Abstract: Measurements from ground-based sun photometer networks can be used both to provide ground-truth validation of satellite aerosol retrievals and to produce a land-based aerosol climatology that is complementary to satellite ...
Global Two-Channel AVHRR Retrievals of Aerosol Properties over the Ocean for the Period of NOAA-9 Observations and Preliminary Retrievals Using NOAA-7 and NOAA-11 Data
Publisher: American Meteorological Society
Abstract: Described is an improved algorithm that uses channel 1 and 2 radiances of the Advanced Very High Resolution Radiometer (AVHRR) to retrieve the aerosol optical thickness and Ångström exponent over the ocean. Specifically ...
Remote Sensing of Atmospheric Aerosols and Trace Gases by Means of Multifilter Rotating Shadowband Radiometer. Part I: Retrieval Algorithm
Publisher: American Meteorological Society
Abstract: A retrieval algorithm for processing multifilter rotating shadowband radiometer (MFRSR) data from clear and partially cloudy days is described and validated. This method, while complementary to the Langley approach, uses ...
Scaling Properties of Aerosol Optical Thickness Retrieved from Ground-Based Measurements
Publisher: American Meteorological Society
Abstract: Statistical scale-by-scale analysis, for the first time, has been applied to the aerosol optical thickness (AOT) retrieved from the Multi-Filter Rotating Shadowband Radiometer (MFRSR) network. The MFRSR data were collected ...
