Low-Frequency Variations of Circulation and High Cloudiness in the Northern Extratropics: Spatial and Temporal Relationships
Publisher: American Meteorological Society
Abstract: The spatial and temporal relationships between fluctuations in geopotential height and high-cloud fractional area in low-pass (periods greater than 10 days) and intermediate-pass (10?30 days) time scales are investigated ...
Fluctuations of High Clouds and 500-mb Geopotential Heights in Baroclinic Waveguides
Publisher: American Meteorological Society
Abstract: A time filter that passes waves with periods in the 2.5-6.0 day band is applied to a six-winter record of the Nimbus-7 THIR/TOMS high cloudiness and the NMC 500-mb geopotential height in the northern extratropics. The ...
Impacts of Partly Cloudy Pixels on Shortwave Broadband Irradiance Computations
Publisher: American Meteorological Society
Abstract: AbstractBecause of the limitation of the spatial resolution of satellite sensors, satellite pixels identified as cloudy are often partly cloudy. For the first time, this study demonstrates the bias in shortwave (SW) broadband ...
Computation of Domain-Averaged Irradiance Using Satellite-Derived Cloud Properties
Publisher: American Meteorological Society
Abstract: The respective errors caused by the gamma-weighted two-stream approximation and the effective thickness approximation for computing the domain-averaged broadband shortwave irradiance are evaluated using cloud optical ...
Cross Correlations between the Radiation and Atmospheric Variables in a General Circulation Model and in Satellite Data
Publisher: American Meteorological Society
Abstract: The classical picture of the influence of midlatitude troughs on cloud patterns is investigated in a general circulation model (GCM) and in satellite and National Meteorological Centre (NMC) data by comparing the cross ...
Cloud Effects on the Meridional Atmospheric Energy Budget Estimated from Clouds and the Earth’s Radiant Energy System (CERES) Data
Publisher: American Meteorological Society
Abstract: The zonal mean atmospheric cloud radiative effect, defined as the difference between the top-of-the-atmosphere (TOA) and surface cloud radiative effects, is estimated from 3 yr of Clouds and the Earth?s Radiant Energy ...
The Relationship of Extratropical Outgoing Longwave Radiation to Monthly Geopotential Teleconnection Patterns
Publisher: American Meteorological Society
Abstract: The relationship between low frequency variations in extratropical fields of outgoing longwave radiation (OLR) and geopotential teleconnection patterns as determined by rotated principal components (RPC) analysis of the ...
Retrieval of Atmospheric and Cloud Property Anomalies and Their Trend from Temporally and Spatially Averaged Infrared Spectra Observed from Space
Publisher: American Meteorological Society
Abstract: surface, atmospheric, and cloud (fraction, height, optical thickness, and particle size) property anomaly retrieval from highly averaged longwave spectral radiances is simulated using 28 years of reanalysis. Instantaneous ...
An Algorithm for the Constraining of Radiative Transfer Calculations to CERES-Observed Broadband Top-of-Atmosphere Irradiance
Publisher: American Meteorological Society
Abstract: ASA?s Clouds and the Earth?s Radiant Energy System (CERES) project is responsible for operation and data processing of observations from scanning radiometers on board the Tropical Rainfall Measuring Mission (TRMM), Terra, ...
