Total column water vapor retrieval methods and results comparison by using sun photometer[J]. Journal of Remote Sensing, 2011,15(3):568-577. DOI: 10.11834/jrs.20110099.
methods of retrieving total column water vapor by using sun photometer are described in detail
which include single-channel method and double-channel method
and the latter can be achieved by using different non-water channel.The influence of aerosol optic depth and Rayleigh are considered
and the data acquired by radiosonde are used as true value of total column water vapor.Analysis on errors shows the retrieved results are very close by using varied methods.In practice
each method can be equally used to retrieve columnar water vapor content.
