An Intruduction of WMO 8th Radiosondes Intercomparison and Integrated Remote Instruments Experiment[J]. Advances in Earth Science, 2012, 27(8): 916-924.

WMO 8th international radiosondes inter-comparison and integrated remote instruments experiment provide abundant high quality data, which help to analyze the capability of radiosondes, and evaluate infrared-radiation impact on temperature sensor and humidity sensor bias. By this experimentation, the advantages and disadvantages of China-made X-band polarize radar and Ka-band cloud radar   and  laser radar, MPL, Ceilometer etc. are evaluated. Some studies were devoted  to improve the key algorithms such as microwave radiometer temperature and humidity measurement, the X-band and Ka-band radars echo attenuation correction, Doppler wind field inversion,cloud classification and upper air wind measurement. Furthermore, the local clouds,tropical convective system and sea-land wind systems are detected by using the remote instruments and  the results are delighting. Similarly, this experiment also provides a good case for researching how to organize preferably integrated remote instruments observation test for the future.
