The ground-based 12-channel radiometer has been observing for about one year(from August,2005 to August,2006).The coefficient of the integrated water vapor between the radiometer and the radiosonde is above 0.97.The Temperature profile,the relative humidity profile and the water vapor profile can be obtained by the neural network algorithm.The three kinds of profiles are compared between the radiometer and the radiosonde.Although there are some difference between the radiometer and the radiosonde for the three kinds of profile,the profiles of the radiometer are valuable for its time continuity,un-attendant and less cost,and so on.There is a strong sand storm on April 17,2006 in Beijing.The maximum integrated water vapor on that day is 2.25 cm,much larger than other day's in April.The mean integrated water vapor is 1.057 cm in April.On the other hand,during that time,the temperature of the boundary layer,from the surface to the 1 km,went up.It means that the thermodynamic structure of the boundary layer will have some change,during the sand storm.All these atmospheric characteristics can be observed by the ground-based 12-channel radiometer.
