Satellite remote sensing observations can be used to measure sea level pressure, according to a recent Chinese research.
Scientists from the National？Space？Science？Center proposed a new method to obtain high temporal and spatial resolution sea level pressure through remote sensing observation. They testified the method using observations from U.S. weather satellite Suomi NPP.
Sea level pressure is a very important meteorological index for weather forecasting. It is mainly measured by weather buoys and merchant ships.
Combining the satellite observations, scientists set up an estimation model for sea level pressure and assessed the model with in-situ buoy measurements.
Scientists say the method has high accuracy in estimating sea level pressure over middle and low latitude areas, and may lead to more precise weather forecasts.
The research was published in the "Journal of Geophysical Research: Oceans." (Xinhua)
