SoMMet - Metrology for multi-scale monitoring of soil moisture

地表淡水主要以土壤水分的形式存在，是影响农业、天气和气候的关键资源，受到气候变化和环境退化的严重影响。任何以全球和欧洲土壤湿度评估为目标的监测都需要使用多尺度方法，其中包括从点尺度传感器、中尺度宇宙射线中子传感（CRNS）到大规模卫星遥感的技术。该项目的总体目标是开发新的计量工具，并为从分米到公里的多个横向尺度的土壤湿度测量建立计量基础。从而确保各种土壤湿度测量方法的可追溯性和协调性，对水管理战略和气候变化监测有用。

Fresh water at the land surface, primarily in the form of soil moisture, is a key resource influencing agriculture, weather and climate, and it is seriously affected by climate change and environmental degradation. Any monitoring that targets global and European soil moisture assessment will require the use of a multi-scale approach, which includes techniques from point-scale sensors, intermediate-scale cosmic-ray neutron sensing (CRNS) to large-scale satellite remote sensing. The overall objective of this project is to develop novel metrological tools and establish a metrological foundation for soil moisture measurements on multiple lateral scales, ranging from decimetre to kilometre. Thereby ensuring the traceability and harmonisation of the various soil moisture measurement methods, useful for water management strategies and climate change monitoring.
