In this study, the regional Weather Research and Forecasting model (WRF)-based quantitative precipitation forecasts (QPFs) are conducted for an extreme Meiyu rainfall event over East Asia in 2020. The data of water vapor channels 9 10 from Advanced Geosynchronous Radiation Imager (AGRI) onboard Fengyun-4A (FY-4A) satellite assimilated through Gridpoint Statistical Interpolation (GSI) system. It...

Atmospheric temperature is one of the most important climate variables. This observational study presents detailed descriptions of the temperature variability imprinted in the 9-year brightness temperature data acquired by the Advanced Microwave Sounding UnitInstrument A (AMSU-A) aboard Aqua since September 2002 over tropical oceans. A non-linear, adaptive method called the Ensemble Joint Multi...

This paper presents a new microwave snow emissivity model which is empirically derived from satellite retrievals and ground-based measurements. This model produces a variety of snow emissivity spectra at microwave frequencies according to snow types. As part of this model, an algorithm is also developed to classify snow type using the Advanced Microwave Sounding Unit (AMSU) measurements at 23.8...

This study investigated the impact of assimilation satellite radiance observations in a three-dimensional variational data system (3DVAR) that could improve tracking and intensity forecasts Tropical Storm Dianmu 2021, which occurred over parts southeast mainland Asia. The weather research forecasting (WRF) model was used to conduct experiments storm. Four sets numerical were performed using WRF...

Clouds are both absorbers of outgoing longwave radiation and reflectors of incoming solar radiation. Due to their crucial role, the knowledge of the horizontal and vertical distribution and the optical properties of globally distributed clouds are of fundamental importance to the understanding of the radiation and heat balance, weather and climate of the earth and the atmosphere. Measurements o...

[1] A comparison between the fast radiative transfer model Radiative Transfer for the TIROS Operational Vertical Sounder (RTTOV-7) and the physical radiative transfer model Atmospheric Radiative Transfer Simulator (ARTS) was carried out. Radiances were simulated for the sounding channels of the Advanced Microwave Sounding Unit B (AMSU-B) for the whole globe for a single time of a single day (1 ...

A method to compare upper tropospheric humidity (UTH) from satellite and radiosonde data has been applied to the European radiosonde stations. The method uses microwave data as a benchmark for monitoring the performance of the stations. The present study utilizes three years (2001–2003) of data from channel 18 (183.31±1.00 GHz) of the Advanced Microwave Sounding Unit-B (AMSU-B) aboard the satel...
