The study looked at how well satellite data matches up with weather balloon data over the Tibetan Plateau. They found that the satellite data is pretty accurate below 200 hPa, especially in the southeast and between 300-600 hPa. The differences between the two types of data are generally small below 250 hPa, especially in high-altitude areas. Overall, the satellite data gives a good picture of water vapor patterns and changes in the region, especially below 200 hPa. However, there are some differences above 250 hPa, so the satellite data might need some adjustments for detailed analysis. They also came up with two formulas for different seasons, even though the differences between seasons are usually small.
