| 摘 要： | 利用CE-318型太阳光度计936nm水汽吸收通道的太阳辐射观测值和太阳光度计在该通道的透过率与水汽量关系，采用瞬态法反演了渤海湾西岸大气柱水汽总量。结果表明：利用太阳光度计936nm通道可以反演晴空大气柱水汽总量，其局限性是要在晴空下使用；渤海湾西岸大气柱水汽含量时间分布极不均匀；不同季节晴空日的水汽含量日变化有所不同。

| Abstract: | Based on the solar radiation observations from CE-318 sun-photometer's 936 nm channel and the relation of water vapor amount and transmissivity,the instantaneous technique is used to retrieve the atmospheric column water vapor amount on the west coast of the Bohai sea gulf.The results show that,using sun-photometer's 936 nm channel observations to retrieve atmospheric water vapor amount is feasible,but only on clear days.Atmospheric water vapor amount on the west coast of the Bohai sea gulf showed complicated temporal variations throughout a year with different diurnal variation patterns on clear days in defferent saesons. |
