We are carrying out research at Palau Islands focusing on the Pacific Area Long-term Atmospheric observation for Understanding of climate change (PALAU) project to understand the mechanism of cloud-precipitation processes, land-atmosphere and air-sea interactions over the warm water pool, focusing on seasonal and intra-seasonal variations. We installed several ground based remote sensors at Peleliu and Aimeliik experimental sites in the Palau. For the present study, Wind Profiler Radar (WPR) and Disdrometer are utilized for preliminary understanding of the marine boundary layer (MBL) evolution, diurnal and seasonal variation of precipitating cloud systems associated with easterly and westerly monsoon. In the present study, long-term (or four year) observations of the marine boundary layer height using wind profiler radar are utilized to estimate ventilation coefficient, a critical parameter in determining air pollution concentration near the surface which signifies the ability for natural ventilation of air over Palau in Tropical Western Pacific Ocean during the period from April 2003 to March 2007. In addition, MBL observations revealed that well-distinguishable features during westerly, easterly and transition period.
