Towards a Machine Learning Snowfall Retrieval Algorithm for GPM-IMERG

16th International Conference on Meteorology, Climatology and Atmospheric Physics—COMECAP 2023, 2023
Remote sensing of snowfall has been proved to be a great challenge since the start of the satellite era. Several techniques have been applied to satellite data to estimate the fraction of frozen precipitation that reaches the surface. This study aims at investigating the efficacy of machine learning (ML), and especially deep learning (DL), in ...

Evaluation of a Novel Climate-Driven SIR Model for Cholera Prediction. [PDF]

Geohealth
Abstract The causative agent of cholera, Vibrio cholerae, is a bacterium native to the aquatic environment and commensal to zooplankton, namely copepods. V. cholerae thrives in warm, moderately saline water and its incidence is strongly influenced by environmental factors, which have proven critical for predictive awareness of cholera by identifying ...

Improving an Extreme Rainfall Detection System with GPM IMERG data [PDF]

Remote Sensing, 2019
Many studies have shown a growing trend in terms of frequency and severity of extreme events. As never before, having tools capable to monitor the amount of rain that reaches the Earth’s surface has become a key point for the identification of areas potentially affected by floods.

Evaluation of GPM IMERG Products for Extreme Precipitation over Indonesia

Journal of Physics: Conference Series, 2022
Abstract Accurate information on extreme rain is essential for vulnerability analysis and early warning systems of hydrometeorological disasters. One newly launched satellite that can provide information about extreme precipitation is the Global Precipitation Measurement (GPM), which produces half-hour grid data through the Integrated ...

Satellite-based high-resolution mapping of rainfall over southern Africa [PDF]

Atmospheric Measurement Techniques, 2017
A spatially explicit mapping of rainfall is necessary for southern Africa for eco-climatological studies or nowcasting but accurate estimates are still a challenging task. This study presents a method to estimate hourly rainfall based on data from the

Evaluation of Heavy Precipitation Simulated by the WRF Model Using 4D-Var Data Assimilation with TRMM 3B42 and GPM IMERG over the Huaihe River Basin, China

Remote Sensing, 2018
To obtain independent, consecutive, and high-resolution precipitation data, the four-dimensional variational (4D-Var) method was applied to directly assimilate satellite precipitation products into the Weather Research and Forecasting (WRF) model.
