RISRelationship between Solar Net Radiative Fluxes at the Top of the Atmosphere and at the Surface
Publisher: American Meteorological Society
Abstract: Previous work has discussed the existence of a linear relationship between the net solar radiative flux densities at the surface and at the top of the atmosphere (TOA) that can be exploited for inferring the net surface ...
Validation of the Upper Tropospheric Relative Humidity Determined from METEOSAT Data
Publisher: American Meteorological Society
Abstract: The purpose of this note is to ?validate? the upper tropospheric humidity (UTH) operationally extracted from the 6.3 ?m channel data of METEOSAT. The validation is carded out by comparing the satellite data with observed ...
Estimation of the Upper Tropospheric Relative Humidity Field from METFOSAT Water Vapor Image Data
Publisher: American Meteorological Society
Abstract: A retrieval method is described for estimating a mean column value of the upper tropospheric relative humidity (UTH) from radiance measurements in the 6.3 ?m channel of the geostationary satellite METEOSAT. The physical ...
Water Vapor–Induced OLR Variations Associated with High Cloud Changes over the Tropics: A Study from Meteosat-5 Observations
Publisher: American Meteorological Society
Abstract: Subdividing the Indian Ocean domain into three areas: (i) a moist cloudy area due to tropical deep convection, (ii) a moist clear area fed by the evaporation of hydrometeors from adjacent high clouds, and (iii) a dry area ...
A Look at the Evolution of Meteorological Satellites: Advancing Capabilities and Meeting User Requirements
Publisher: American Meteorological Society
Abstract: n this paper, the authors offer their observations from more than 30 years of involvement in the evolution of the space-based meteorological remote sensing systems. Successes and issues from the past are recalled that ...
Atlantic Data Coverage by METEOSAT-3
Publisher: American Meteorological Society
Abstract: On 1 August 1991, a European geostationary satellite (METEOSAT-3) started operation from a new position at 50°W. This extends westward the European capability to monitor midlatitude storm tracks and assists the National ...
A Comparison of Several Techniques to Assign Heights to Cloud Tracers
Publisher: American Meteorological Society
Abstract: Satellite-derived cloud-motion vector (CMV) production has been troubled by inaccurate height assignment of cloud tracers, especially in thin semitransparent clouds. This paper presents the results of an intercomparison ...
Low-Level Cloud Motion Winds from Meteosat High-Resolution Visible Imagery
Publisher: American Meteorological Society
Abstract: Low-level wind fields over the Atlantic have been derived from clouds in Meteosat high-resolution visible images experimentally with one production cycle per day over a period of more than 1 yr. The cloud motion winds from ...
Dry Bias in Satellite-Derived Clear-Sky Water Vapor and Its Contribution to Longwave Cloud Radiative Forcing
Publisher: American Meteorological Society
Abstract: In this paper, the amount of satellite-derived longwave cloud radiative forcing (CRF) that is due to an increase in upper-tropospheric water vapor associated with the evolution from clear-sky to the observed all-sky ...
