Collaborative Research: Snow-Soil Moisture-Monsoon Relationship

这个合作项目涉及A. Robock和D.罗格斯大学的罗宾逊和K.马里兰州大学的Vinnikov将探索雪和土壤湿度异常与印度夏季风的时间和强度之间的联系。 这项分析将包括利用特别观测和NCEP再分析数据来检查雪、土壤湿度、降雨和环流异常以及海面温度之间的联系。 主要研究人员将利用新近获得的土壤湿度观测数据库，该数据库有400多个观测站，覆盖欧亚大陆的大部分地区，包括前苏联、蒙古、中国和印度，沿着还有一套最新的积雪范围和雪水当量观测数据。 这项活动的一个关键部分将是PI对组成数据集的各种观测结果进行仔细评估和质量控制。 该数据集将通过网络提供给更广泛的社区。

This collaborative project involving Drs. A. Robock and D. Robinson of Rutgers University and Dr. K. Vinnikov of the University of Maryland will explore the connection between snow and soil moisture anomalies and the timing and strength of the Indian summer monsoon. This analysis will include examining the links among snow, soil moisture, rainfall and circulation anomalies, and sea surface temperatures using special observations and the NCEP reanalysis data. The principal investigators (PIs) will exploit a newly available data base of soil moisture observations, with more than 400 stations covering most of Eurasia, including the former Soviet Union, Mongolia, China, and India, along with an updated data set of snow extent and snow water equivalent observations. A critical part of the activity will be the PIs' careful assessment and quality control of the diverse observations that make up the data set. The data set will be made available to the wider community via the web.
