Abstract EN
Satellite remote sensing of the atmospheric water vapor distribution over the oceans is essential for both weather and climate studies.
Satellite onboard microwave radiometer is capable of measuring the water vapor over the oceans under all weather conditions.
This study assessed the accuracies of precipitable water vapor (PWV) products over the south and east China seas derived from the Global Precipitation Measurement Microwave Imager (GMI), using radiosonde and GNSS (Global Navigation Satellite System) located at islands and coasts as truth.
PWV measurements from 14 radiosonde and 5 GNSS stations over the period of 2014–2017 were included in the assessments.
Results show that the GMI 3-day composites have an accuracy of better than 5 mm.
A further evaluation shows that RMS (root mean square) errors of the GMI 3-day composites vary greatly in the range of 3∼14 mm at different radiosonde/GNSS sites.
GMI 3-day composites show very good agreements with radiosonde and GNSS measured PWVs with correlation coefficients of 0.896 and 0.970, respectively.
The application of GMI products demonstrates that it is possible to reveal the weather front, moisture advection, transportation, and convergence during the Meiyu rainfall.
This work indicates that the GMI PWV products can contribute to various studies such as climate change, hydrologic cycle, and weather forecasting.
