Field experiments have played a critical role in the development and implementation of satellite soil moisture missions. A review of key experiments is presented that includes tower-, aircraft, and satellite-focused efforts conducted over four decades that have supported two dedicated satellite missions; Soil Moisture Ocean Salinity (SMOS) and Soil Moisture Active passive (SMAP).
Programs of scientific research, like other formally organized collective practices, meet the materiality of the world in complex and dynamic ways. This intersection has important and under explored consequences for the planning and practice of distributed scientific collaboration, including programs of large-scale infrastructure development currently underway across a range of scientific fields and...
The National Aeronautics and Space Administration's (NASA) proposed Soil Moisture Active Passive (SMAP) satellite mission (2014) will include a radar system that will provide L-band multi-polarization backscatter at a constant incidence angle of 40 . During the pre-launch phase of the project, there is a need for observations that will support the radar-based soil moisture algorithm development...
The world of science has long been a source of new models, ideas, and technologies in the practice of distributed group collaboration. Recent national-scale investments in 'e-science' or 'cyberinfrastructure, ' continue this trend, promising to extend scientific collaboration through space (geographic and disciplinary) but also time: building new monitoring systems while opening up existing long-term...
In order to validation soil moisture products from remote sensing platforms, an accurate and verified ground dataset is necessary. However, the diversity of in situ soil moisture networks makes the aggregation of available data difficult because of the difference in quality and accuracy. A testbed was initiated as part of the Soil Moisture Active Passive satellite mission to intercompare the current...
