RISCorrection of Three-Dimensional Effects for Passive Microwave Remote Sensing of Convective Clouds
Publisher: American Meteorological Society
Abstract: This paper presents a simple approach to adjust microwave brightness temperature distributions obtained from slant-path measurements for projection effects. Horizontal displacement in the direction of sight is caused by ...
Verification of TMI-Adjusted Rainfall Analyses of Tropical Cyclones at ECMWF Using TRMM Precipitation Radar
Publisher: American Meteorological Society
Abstract: A validation of passive microwave?adjusted rainfall analyses of tropical cyclones using spaceborne radar data is presented. This effort is part of the one-dimensional plus four-dimensional variational (1D+4D-Var) rain ...
The Effect of the Melting Layer on the Microwave Emission of Clouds over the Ocean
Publisher: American Meteorological Society
Abstract: A study was carried out in order to estimate the effect of melting particles on simulated brightness temperatures at microwave frequencies between 10.7 and 85.5 GHz for precipitation over the ocean. The meteorological model ...
Outlook for Combined TMI–VIRS Algorithms for TRMM: Lessons from the PIP and AIP Projects
Publisher: American Meteorological Society
Abstract: The status of current rainfall-retrieval techniques by satellite radiometry has been evaluated by recent international algorithm intercomparison projects. As a general result, passive microwave techniques perform superiorly ...
Scaling of GNSS Radio Occultation Impact with Observation Number Using an Ensemble of Data Assimilations
Publisher: American Meteorological Society
Abstract: n ensemble of data assimilations (EDA) approach is used to estimate how the impact of Global Navigation Satellite System (GNSS) radio occultation (RO) measurements scales as a function of observation number in the ECMWF ...
Impact of SSM/I Observations Related to Moisture, Clouds, and Precipitation on Global NWP Forecast Skill
Publisher: American Meteorological Society
Abstract: This paper presents the results from the Observing System Experiments (OSEs) with the current ECMWF data assimilation and modeling system for quantifying the impact on both analysis and forecast quality of Special Sensor ...
Intercomparison of High-Resolution Precipitation Products over Northwest Europe
Publisher: American Meteorological Society
Abstract: atellite-derived high-resolution precipitation products (HRPP) have been developed to address the needs of the user community and are now available with 0.25° ? 0.25° (or less) subdaily resolutions. This paper evaluates a ...
Model Clouds over Oceans as Seen from Space: Comparison with HIRS/2 and MSU Radiances
Publisher: American Meteorological Society
Abstract: Radiation observations are a key element in the evaluation of the 40-yr reanalysis at the European Centre for Medium-Range Weather Forecasts. This paper uses the High-Resolution Infrared Radiation Sounder/2 (HIRS/2) and ...
Results of WetNet PIP-2 Project
Publisher: American Meteorological Society
Abstract: The second WetNet Precipitation Intercomparison Project (PIP-2) evaluates the performance of 20 satellite precipitation retrieval algorithms, implemented for application with Special Sensor Microwave/Imager (SSM/I) passive ...
