Abstract :
Cloud plays one of the biggest unknown factors in global warming prediction. To observe the 3-dimensional profiles of clouds, a mm-wave multi-parameter airborne cloud profiling radar (nickname: SPIDER) has been developed by the Communications Research Laboratory (CRL). SPIDER was designed for airborne as well as ground-based use. The frequency of the radar is in the W-band (95 GHz) giving it enough sensitivity for cloud particle measurements. The multi-parameter function can be used to identify cloud particles. The antenna scanning mechanism is useful for observing dimensional profiles of clouds. In January 1998, the first experiment to observe clouds was performed in Japan with SPIDER. The preliminary results are shown
