Soil Moisture Retrieval and Assimilation for Improved Hydrologic Applications

McMaster Mesonet是在安大略西南部建立的一个连续的土壤湿度监测网络。它包括4个气象站和216个时域反射仪（TDR）土壤探头，这是加拿大有史以来在研究实验中建立的最大数量的土壤水分监测探头。这是加拿大唯一一个提供连续高分辨率土壤湿度数据的土壤湿度研究实验。Mesonet数据集对于开发新的信息处理技术，即从遥感（如雷达卫星）地表观测中提取分布式土壤水分信息所需的数据检索和同化技术至关重要。 空间分布的土壤湿度数据对于水文学中的各种应用是必不可少的，例如改进洪水预报、地下水补给估计和地下水化学浸出的建模以及干旱预测。

McMaster Mesonet is a continuous soil moisture monitoring network established in Southwestern Ontario. It includes 4 weather stations and 216 Time Domain Reflectomers (TDR) soil probes which is the largest number of soil moisture monitoring probes ever established in a research experiment in Canada. It is the only soil moisture research experiment in Canada that provides continuous high resolution soil moisture data. The Mesonet datasets are critical for the development of new information processing technologies namely data retrieval and assimilation techniques needed to extract distributed soil moisture information from remote sensing (e.g. Radarsat) land surface observations. Spatially distributed soil moisture data is essential for various applications in hydrology such as improved flood forecasting, groundwater recharge estimation and the modeling of chemical leaching to groundwater, and drought prediction.
