Using GPS PWV as a New Approach to Correlate Solar-Induced on Antarctic Climate

This paper observes the characteristics of Antarctic precipitable water vapor (PWV) as a climate parameter affected by solar radiation at Scott Base (77.85°S, 166.76°E), Davis (68.58°S, 77.97°E) and Syowa (69.00°S, 39.58°E) using the ground-based GPS and the surface meteorological measurements. As the Sun plays a central role in the hydrological cycle and precipitation, the associations between water vapor and solar radiation have been studied to understand the current global climate change. Analysis of data gathered for the period from 2003 to 2008 showed that the observations between PWV and solar radiation shows strong relationships with correlation coefficients 0.84 for diffuse and 0.79 for global radiation. Based on their strong relationship, PWV data and analysis have done suggests that GPS can be used as a new approach to study the interaction of solar-induced climate change.
