Abstract |
This article presents a statistical correlation between GPS precipitable water vapor and
meteorological data, i.e., surface temperature, air pressure, relative humidity, dew point
temperature, and water vapor pressure by using linear regression. The data, recorded over a 4-year
period, was used as an estimation of missing GPS precipitable water vapor data from discontinuous
recordings. A multiple linear regression equation showed a correlation among zenith wet
delay(ZWD), water vapor pressure(e) and surface temperature(T) was ZWD(e,T) = 17.4952e-0.8281T-93.164, with a coefficient of determination(R
2
) of 0.725, a mean absolute error of 8.71
mm, a root mean square error of 10.39 mm, and a mean absolute percentage error of 18.63%. The
equation obtained can be used to estimate GPS precipitable water vapor data which is missing from
recordings due to accident or technological error. |
