The researchers analyzed GPS data from Harbin station in June 2004 to improve the accuracy of measuring water vapor in the atmosphere. They found that using broadcast ephemeris in GPS can lead to errors in measuring water vapor. Errors in GPS coordinates can also affect the accuracy of water vapor measurements. Different settings in GPS and models can impact the results of measuring water vapor in the atmosphere.
