RISRadiative Transfer to Space through a Precipitating Cloud at Multiple Microwave Frequencies. Part I: Model Description
Publisher: American Meteorological Society
Abstract: In a two-part study we investigate the impact of time-dependent cloud microphysical structure on the transfer to space of passive microwave radiation at several frequencies across the EHF and lower SHF portions of the ...
Radiative Transfer to Space through a Precipitating Cloud at Multiple Microwave Frequencies. Part II: Results and Analysis
Publisher: American Meteorological Society
Abstract: The time-dependent role of cloud liquid water in conjunction with its vertical heterogeneities on top-of-atmosphere (TOA) passive microwave brightness temperatures is investigated. A cloud simulation is used to specify the ...
Energy Exchange and Temperature of Aerosols in the Earth's Atmosphere (0-60 km)
Publisher: American Meteorological Society
Abstract: A previous analysis (Fiocco et al., 1975) of the energetic equilibrium of small particles in the earth's upper atmosphere is extended to the 0?60 km region. The analysis is based on establishing a balance among the energy ...
Foundations for Statistical Physical Precipitation Retrieval from Passive Microwave Satellite Measurements. Part II: Emission-Source and Generalized Weighting-Function Properties of a Time-dependent Cloud-Radiation Model
Publisher: American Meteorological Society
Abstract: We present the second part of a study on the development of a framework for precipitation retrieval from space-based passive microwave measurements using a three-dimensional time-dependent cloud model to establish the ...
Simulation of Microwave Brightness Temperatures of an Evolving Hailstorm at SSM/I Frequencies
Publisher: American Meteorological Society
Abstract: A simulation of the appearance of an intense hailstorm in the passive microwave spectrum is conducted in order to characterize the vertical sources of radiation that contribute to the top-of-atmosphere microwave brightness ...
Foundations for Statistical-Physical Precipitation Retrieval from Passive Microwave Satellite Measurements. Part I: Brightness-Temperature Properties of a Time-dependent Cloud-Radiation Model
Publisher: American Meteorological Society
Abstract: A cloud-radiation model is used to investigate the relationship between emerging microwave brightness temperatures (TB's) and vertically distributed mixtures of liquid and frozen hydrometeors as a means to establish the ...
Estimating 13.8-GHz Path-Integrated Attenuation from 10.7-GHz Brightness Temperatures for the TRMM Combined PR–TMI Precipitation Algorithm
Publisher: American Meteorological Society
Abstract: This study presents research in support of the design and implementation of a combined radar?radiometer algorithm to be used for precipitation retrieval during the Tropical Rainfall Measuring Mission (TRMM). The combined ...
Mathematical–Physical Framework for Retrieval of Rain DSD Properties from Dual-Frequency Ku–Ka-Band Satellite Radar
Publisher: American Meteorological Society
Abstract: In developing the upcoming Global Precipitation Measurement (GPM) mission, a dual-frequency Ku?Ka-band radar system will be used to measure rainfall in such a fashion that the reflectivity ratio intrinsic to the measurement ...
Use of Cloud Model Microphysics for Passive Microwave-Based Precipitation Retrieval: Significance of Consistency between Model and Measurement Manifolds
Publisher: American Meteorological Society
Abstract: Precipitation estimation from passive microwave radiometry based on physically based profile retrieval algorithms must be aided by a microphysical generator providing structure information on the lower portions of the ...
