Improvement of the GSMaP Precipitation Retrieval Algorithm for Microwave Sounders Over Coast

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
We have improved a rainfall retrieval algorithm over coast for the Advanced Microwave Sounding Unit (AMSU) in order to upgrade to the Global Satellite Mapping of Precipitation (GSMaP) product version 8. As for the algorithm of product version 7, the zonal-mean monthly precipitation tends to overestimate low latitude coastal areas and to be a missing ...

Recent improvements in the global satellite mapping of precipitation (GSMaP)

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
The Global Satellite Mapping of Precipitation (GSMaP) product, which was developed toward the Global Precipitation Measurement (GPM), is operating and distributed in near-real-time basis at the Japan Aerospace Exploration Agency (JAXA). In this paper, we will introduce development status of the latest GSMaP algorithm, which will be distributed as one ...

Precipitation Extremes Monitoring Using Global Satellite Mapping of Precipitation (GSMaP) Products

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
This study describes a usefulness of GSMaP Near-real-time Gauge-adjusted Rainfall Product (GSMaP_Gauge_NRT) provided by JAXA for monitoring drought from one-month to three-month and heavy rainfall from pentads up to a month. GSMaP_Gauge_NRT is processed 4 hours after observation and is the gauge-adjusted rainfall with spatial resolution of 0.1 degrees ...

Automatic region growing method using GSmap and spatial information on ultrasound images

2010 18th Iranian Conference on Electrical Engineering, 2010
Ultrasound image segmentation is a critical issue in medical image analysis and visualization. Identifying the boundaries of abnormal regions in some cases is challenging task. In this paper, we propose a full automatic region growing algorithm. The seed point has been automatically selected based on textural features from co-occurrence matrix and run ...

Tracking a Decade of GSMaP-Derived Precipitating Systems with pyForTraCC

Precipitating systems (PSs) are key components of atmospheric dynamics, shaping both regional and global hydrological cycles. Accurate identification, tracking, and forecasting of these systems are essential for improving weather and climate predictions and mitigating the socio-economic impacts of extreme events.
