A Study of the Remote Sensing in Columnar Water Vapour Content from Spectral Direct Solar Radiation[J]. Journal of Remote Sensing, 1996, (4). DOI: 10.11834/jrs.1996038.
There is the information content of atmospheric water vapour in direct solar radiation measured with a solar spectrometer. A deduction approach is presented for retrieving the columnar water vapour content. On the basis of the random model rather
than the Bouguer Law
the retrieval for water vapour absorption is more reasonable. Three Water vapour absorbing bands
α
β
ρ στ
are selected in the joint deduction of water vapour content。 It is shown that the columnar water .vapour content from the remote sensing data is quite consistent with that from radiosonde data.
