Continuous Real-Time and Near-Real-Time Monitoring of Tropospheric Water Vapor in Arctic Siberia by Means of GPS

这项提议涉及利用全球定位系统监测北极和西伯利亚次北极地区可降水量的需要，以及在东北亚全球定位系统形变阵列上近实时收集的气象观测，目前东北亚全球定位系统变形阵列不包括西伯利亚。对西伯利亚上空PWV的平滑观测对于全球水汽数据集和全球数值气候模式的校准和验证非常重要。

This proposal addresses the need for monitoring preciptable water vapor (PWV) in the Arctic and sub-Arctic regions of Siberia using the Global Positioning System (GPS) and meteorological observations collected in near-real time over the Northeast Asia GPS Deformation Array (NEDA), which currently does not include Siberia. Smoothed observations of PWV over Siberia are important for calibration and validation of global water vapor data sets and global numerical climate models.
