Abstract :
In this paper, the effects of mean weighted temperature (Tm) for the calculation of perceptible water vapor (PWV) from GPS data is analyzed. Tm for Singapore is estimated using surface temperature information (Ts). To analyze the effect of Tm for calculating PWV, PWV for four consecutive months are calculated using the estimated equation and compared to PWV calculated from the well-known Bevis equation. The results are analyzed and it is concluded that different relationships for Tm and Ts has little effects on the calculated PWV values.
