The authors of this book have been approached by consulting engineers:'You know about remote sensing and thus you can obtain hydrological information where no data exist, even without ground measurements, so that I can design the required capacity of

Passive microwave airborne remote sensing was employed to collect daily brightness temperature (TB) and near-surface (0–5 cm depth) soil water content (referred to as “soil water content”) data during June 10–18, 1992, in the Little Washita w

Images remotely sensed aboard aircraft during FIFE, namely, PBMR (microwave) soil nwisture and NS001 thermal infrared surface temperature, were mapped on the same coordinate system covering the 20 km×20 km experimental site. For both kinds of image

SIR-C L-band measurements over the Little Washita River watershed in Chickasha, Oklahama during 11–17 April 1994 have been analyzed for studying the change of soil moisture in the region. Two algorithms developed recently for estimation of moisture

This chapter documents the use of simulated Moderate Resolution Imaging Spectroradiometer land use/land cover (MODIS 12 Q1), NASA-LIS generated precipitation and evapo-transpiration (ET), and Shuttle Radar Topography Mission (SRTM) datasets (in conju

The case is made that the hydrological sciences are data limited and that future progress in understanding hydrological processes is hampered by the lack of adequate data. The future applications of remote sensing to hydrology should provide new type

Passive and active microwave remote sensing instruments are capable of measuring the surface soil moisture (0–5 cm) and can be implemented on high altitude platforms, e.g. spacecraft, for repetitive large area observations. The amount of water pres

Remote sensing has held a great deal of promise for hydrology, mainly because of the potential to observe areas and entire river basins rather than merely points. In addition, as the remote sensing science has developed we have learned of the potenti

Ecosystem process, biosphere-atmosphere transfer, and carbon exchange models all require parameterization of the land surface, including land vegetation cover and soil moisture. Although not yet a demonstrated global capability, the most feasible met

MACHYDR0'90 was an experiment conducted in Pennsylvania in 1990 to study the synergistic use of remote sensors in multitemporal hydrologic studies. As part of this mission the pushbroom microwave radiometer was flown and used to produce brightness te
