This study focuses on determining bathymetric changes around offshore islands of Vietnam using remote sensing data available on the Google Earth Engine cloud platform. Sentinel2 multispectral satellite imagery was collected over three time periods, January 14, 2020, June 5, 2020 and June 15, 2021, coinciding with the wind season to analyze and calculate bathymetric changes.

This paper presents a novel approach to enhancing the accuracy of precipitation estimation in Central Vietnam using the Extreme Gradient Boosting (XGBoost) machine learning model. The proposed method integrates multi-source data, combining satellite imagery from Himawari-8, atmospheric reanalysis from ERA-5, and digital elevation models from ASTER DEM to train the model.

Research objectives: Collect and process the magnetic data from CHAMP satellite and from the magnetic observatories within 6 years (from 2002-2007); study the method to separate magnetic field caused by EEJ from the observed data; identify some parameters of EEJ in all over meridians and study the variation of EEJ in space and time. The variation of EEJ in longitude, latitude and local time.
