This paper is mainly concentrared to the correlation between Total Precipitable Water (TPW) on one single column of the vertical air mass and radar reflectivity (Z) over Kototabang (0.2 S; 100.32 E), Bukittinggi, West Sumatera based on to the analysis of Radio Acoustic Sounding System (RASS) and Boundary Layer Radar (BLR) data during the Coupling Processes of Equatorial Atmosphere (CPEA) Campaign I from April 10 to May 9, 2004 was going on. We firstly reviewed the basic concept of TPW using the Weisner method to estimate the TPW value from the radiosonde data. We reviewed the basic concept of RASS and BLR system also, especially on the Z data analysis. By arranging the mean value of RASS data every 10 minutes and 150 meter in height, respectively, we estimated the TPW values from the RASS data. By analysing the Cross Correlation Function (CCF) of both values taken from SPSS software version 13, we found a good agreement between TPW and Z parameter, especially on 5 May, 2004. The correlation values are 0.05, and 0.61 at around 2.7 and 2.25 km, respectively. Although, the maximum correlation value is only 0.61, but this is still good enough to describe the correlation between TPW and Z.
