摘要:

DTF型系列太阳光度计在合肥地区测量大气气溶胶光学厚度(AOT)和可降水量(PWV),并与其它测量仪器进行对比验证,各仪器之间测量结果日变化趋势具有很好的一致性。对比分析结果显示:太阳光度计之间测量气溶胶光学厚度和可降水量的均方根误差都在8%以内;太阳光度计测量的可降水量与微波辐射计测量的水汽含量进行对比,均方根误差约5%。通过对比验证和误差分析,DTF型太阳光度计测量AOT和PWV具有较高的可靠性。

Abstract:

DTF serial sun-photometers are used to measure aerosol optical thickness and precipitable water vapor in Hefei. They compare with other type instrument by experiment measurement. It is obvious that the daily variation tendency is basically consistent. The errors of computed parameters between DTF sun-photometer and other device are analyzed. The results indicate that the root-mean-square errors of measured aerosol optical thickness and precipitable water vapor are all less than 8%. Precipitable water vapor measured by sun-photometer comparing with microwave radiometer, the root-mean-square error is about 5%. Via comparison certification and error analysis, DTF sun-photometer which is used to sound aerosol optical thickness and precipitable water vapor has high reliability.

Key words: sun-photometer, aerosol optical thickness, precipitable water vapor, error analysis
