Biases in Earth radiation budget observations, Part II: Consistent scene identification and anisotropic factors

Creator:: Ye, Qian and Coakley, James A., Jr.
Abstract:: Simple threshold scene identification methods are developed to reduce the effects of errors in scene identifications on the anisotropy of reflected and emitted radiances inferred from Earth Radiation Budget Experiment (ERBE) scanner observations. The ERBE maximum likelihood estimate (MLE) scene identification is assumed to be accurate for nadir fields of...

Biases in Earth radiation budget observations: 1. Effects of scanner spatial resolution on the observed anisotropy

Creator:: Ye, Qian and Coakley, James A.
Abstract:: The Earth Radiation Budget Experiment (ERBE) used angular direction models (ADMs) to convert satellite scanning radiometer measurements to radiative fluxes at the top of the atmosphere. The ADMs were assumed to depend only on the physical characteristics of the scene being observed, and they were taken to be independent of...

Toward the estimation of errors in cloud cover derived by threshold methods

Creator:: Chang, Fu-Lung
Abstract:: The accurate determination of cloud cover amount is important for characterizing the role of cloud feedbacks in the climate system. Clouds have a large influence on the climate system through their effect on the earth's radiation budget. As indicated by the NASA Earth Radiation Budget Experiment (ERBE), the change in...

The spatial-scale dependence of the observed anisotropy of reflected and emitted radiation

Creator:: Ye, Qian
Abstract:: The Earth Radiation Budget Experiment (ERBE) uses Angular Dependence Models (ADMs) to convert satellite observed radiances to radiative fluxes at the top of the atmosphere. Owing to errors in scene identification and to the relationship between the spatial scales of cloud systems and the spatial resolution of the ERBE scanner,...

Kelvin waves in stratospheric temperature observed by the Microwave Limb Sounder

Creator:: Mote, Philip W., Dunkerton, Timothy J., and Wu, Dong
Abstract:: The three-dimensional (3-D) structure of stratospheric Kelvin waves is revealed using data from the Microwave Limb Sounder for the period July 1992 to April 1993. Four Kelvin wave modes are identified, two for zonal wave number 1 (k = 1) and two for k = 2, using extended empirical orthogonal...

The Diurnal Cycle of Cloud-Top Height and Cloud Cover over the Southeastern Pacific as Observed by GOES-10

Creator:: Painemal, David and Minnis, Patrick
Abstract:: The diurnal cycles in cloud-top height H[subscript top] and cloud fraction (CF) in the southeastern Pacific stratocumulus region were determined for October-November 2008 by analyzing data from Geostationary Operational Environmental Satellite-10 (GOES-10) according to a diurnal/semidiurnal harmonic fitting technique. The value of H[subscript top] was obtained by applying a formula...

Variability of water vapor in the tropical upper troposphere as measured by the Microwave Limb Sounder on UARS

Creator:: Clark, H. L, Harwood, R. S., Mote, Philip W., and Read, W. G.
Abstract:: The Microwave Limb Sounder (MLS), an instrument on the Upper Atmosphere Research Satellite (UARS), measures water vapor in the upper troposphere, with best sensitivity at the standard UARS level at 215 hPa. In this paper, we analyze the MLS observations with a view to characterizing the temporal and zonal variations...

GOES-10 microphysical retrievals in marine warm clouds: Multi-instrument validation and daytime cycle over the southeast Pacific

Creator:: Painemal, David, Minnis, Patrick, Ayers, J. Kirk, and O'Neill, Larry
Abstract:: The daytime evolution of warm cloud microphysical properties over the southeast Pacific during October–November 2008 is investigated with optical/infrared retrievals from the Tenth Geostationary Operational Environmental Satellite (GOES-10) imager. GOES-10 retrievals, produced at NASA Langley Research Center, are validated against in situ aircraft observations and with independent satellite observations. Comparisons...

Modeled and observed longwave radiances at the top of the atmosphere

Creator:: Stone, Kenneth A.
Abstract:: One method of estimating the longwave radiative heating of the atmosphere is to combine satellite observations of emitted radiances with those computed from synoptic temperature and humidity profiles. Modeled and observed radiances are brought into agreement by altering cloud properties or even by adjusting the temperature and water vapor profiles....

A simple model for the cloud adjacency effect and the apparent bluing of aerosols near clouds

Creator:: Marshak, Alexander, Wen, Guoyong, Coakley, James A., Remer, Lorraine A., Loeb, Norman G., and Cahalan, Robert F.
Abstract:: In determining aerosol-cloud interactions, the properties of aerosols must be characterized in the vicinity of clouds. Numerous studies based on satellite observations have reported that aerosol optical depths increase with increasing cloud cover. Part of the increase comes from the humidification and consequent growth of aerosol particles in the moist...
