Based on the nearly coincided and collocated SSM/I and radiosonde data provided by NASDA (Japan), a self-organizing map (SOM) network-based model is developed for retrieving the oceanic total precipitable water (PW) from the SSM/I brightness temperature measurements. The model was firstly trained with the 5/6th of the data and then tested by the rest data. Comparisons of retrieved results with other algorithms show that the SOM model is significantly better than the classical statistically-based algorithms, especially in the low PW regime. The consuming time for PW retrievals with the SOM model is also acceptable in the operational applications.
