The International Soil Moisture Network: a data hosting facility for global in situ soil moisture measurements
In situ measurements of soil moisture are invaluable for calibrating and validating land surface models and satellite-based soil moisture retrievals. In addition, longterm time series of in situ soil moisture measurements themselves can reveal trends in the water cycle related to climate or land cover change. Nevertheless, on a worldwide basis the number of meteorological networks and stations ...
متن کاملEvaluation of AMSR2 soil moisture products over the contiguous United States using in situ data from the International Soil Moisture Network
High quality soil moisture datasets are required for various environmental applications. The launch of the Advanced Microwave Scanning Radiometer 2 (AMSR2) on board the Global Change Observation Mission 1—Water (GCOM-W1) in May 2012 has provided global near-surface soil moisture data, with an average revisit frequency of two days. Since AMSR2 is a new passive microwave system in operation, it i...
متن کاملEstimating Surface Soil Moisture Using Radarsat-2
Extremes in soil moisture, either too much or too little, present a significant risk to agricultural productivity. Managing and mitigating risk requires information and knowledge to assess risk potential, implement risk reduction strategies and deliver responses to this risk. Synthetic aperture radars (SARs) are sensitive to the dielectric properties of soils and are thus well suited to provide...
متن کاملLarge scale evaluation of AMSR soil moisture products based on ground soil moisture network measurements
This paper presents an evaluation of AMSR (Advanced Microwave Scanning Radiometer) soil moisture products, based on the comparison with three ground soil moisture networks. The selected ground sites are representative of various climatic, hydrologic and environmental conditions in temperate and semi-arid areas. They are located in the south-west of France, in the south-east of Australia and in ...
متن کاملSpatial soil moisture scaling structure during Soil Moisture Experiment 2005
Soil moisture state and variability control many hydrological and ecological processes as well as exchanges of energy and water between the land surface and the atmosphere. However, its state and variability are poorly understood at spatial scales larger than the fields (i.e. 1 km2) as well as the ability to extrapolate field scale to larger spatial scales. This study investigates soil moisture...
