Abstract:We propose a method based on weighted mean temperature derived from GPT2w to retrieve precipitable water vapor, and analyze the influence of the weighted mean temperature with systematic correction derived from GPT2w on precipitable water vapor. The results show that the precision of precipitable water vapor based on weighted mean temperature derived from GPT2w is comparable with that of precipitable water vapor based on weighted mean temperature by Bevis formula, and that weighted mean temperature with systematic correction has little influence on precipitable water vapor, the improvement rate is less than 1%.
