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.

该提案解决了利用全球定位系统（GPS）和东北亚GPS变形阵列（NEDA）近实时收集的气象观测资料监测西伯利亚北极和亚北极地区可降水量（PWV）的需求，该阵列目前不包括西伯利亚。西伯利亚PWV的平滑观测对全球水汽数据集和全球数值气候模式的校准和验证具有重要意义。
