Spatio-temporal patterns of field-scale soil moisture and their implications for in situ soil moisture network design
This dissertation describes efforts to overcome the challenges in designing in situ soil moisture observation network. The surface soil moisture data collected at two spatial scales in a working field in Iowa throughout the growing seasons in 2004 to 2008 were used to describe the spatio-temporal characteristics of soil moisture at field scale. The rank stability analysis was used to identify t...
متن کاملThe 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 کاملSpatial Estimation of Soil Moisture and Salinity with Neural Kriging
The study was carried out with 107 measurements of volumetric soil water content (SWC) and electrical conductivity (EC) for soil profile (0-30 cm) and the estimating accuracy of ordinary kriging (OK) and back-propagation neural network (BPNN) was compared. The results showed that BPNN method predicted a slightly better accurate SWC than that of OK, but differences between both methods were not ...
متن کاملSpace-time self-organization of mesoscale rainfall and soil moisture
The eects of mesoscale circulations induced by soil moisture heterogeneities are studied to assess the impact that the coupling of the land surface and the planetary boundary layer has on the rainfall and soil moisture dynamics at dierent scales. Our goal is to single out the most important physical mechanisms which aect the behaviour of the land-atmosphere system at the mesoscale leading to...
