| description | This paper presents the development of T<sub>M</sub> model by using the radiosonde stations from Peninsular Malaysia. Two types of T<sub>M</sub>
model were developed; site-specific and regional models. The result revealed that the estimation from site-specific model has small
improvement compared to the regional model, indicating that the regional model is adequately to use in estimation of GPS-derived
IWV over Peninsular Malaysia. Meanwhile, this study found that the diurnal cycle of T<sub>S</sub> has influenced the T<sub>M</sub>–T<sub>S</sub> relationship. The
separation between daytime and nighttime observation can improve the relationship of T<sub>M</sub>–T<sub>S</sub>. However, the impact of diurnal cycle
to IWV estimation is less than 1 %. The T<sub>M</sub> model from Global and Tropic also been evaluated. The Tropic T<sub>M</sub> model is superior to
be utilized as compared to the Global T<sub>M</sub> model. |
