| 摘 要： | 我们研制了一台太阳红外光谱仪，在地面连续自动地记录了晴天的太阳红外光谱，利用3．434μm（2912cm^-1）波段附近水汽对太阳光谱的吸收反演出整层大气中水汽的总含量，遥测结果与无线电探空相当吻合，经过近一年半的观测，得到了合肥地区垂直气柱中可降水含量的日变化和季节变化规律，并发现气柱中可降水含量与地面露点温度有较好的相关，并对结果进行了讨论。

| Abstract: | Infrared solar spectra on clear days were measured automatically by an infrared solar spectrometer (ISS) capable of 0.4 cm-(-1) resolution developed by us. Precipitable water was retrieved from the recorded infrared solar spectra near 3.434 μm wavelength band,which is absorbed by atmospheric water vapor. Comparison shows that the retrieval result coincides quite well with radiosonde. The characteristics of diurnal and seasonal variation of precipitable water were obtained over Hefei from the measuremental data of nearly 18 months since April of 1997. It is found that the precipitable water is related to surface dew point temperature. The results are also discussed in the paper. |
