Orbital microwave measurement of river discharge and ice status

Abstract: [1] Satellite passive microwave sensors provide global coverage of the Earth's land surface on a near-daily basis without severe interference from cloud cover. Using a strategy first developed for wide-area optical sensors, and in conjunction with even limited ground-based discharge information, such microwave data can be used to estimate river discharge changes, river ice status, and watershed runoff. Water surface area in a river reach increases as flow widens, and any temporally calibrated observation sensi… Show more

“…The flood archive data provided by the DFO have been collected using different methods of observation and validation since 1985 (see the summary of the methods in Brakenridge et al, 2005). In addition, there are more flood warning systems and facilities, transmitting instruments, reporting networks, and communications today at different levels of social and governmental divisions that the DFO is using to provide more comprehensive flood information.…”

“…At the same time, the likely improvements in the accuracy of in situ measurements, advances in satellite and ground-based sensors, data storage, and transfer facilities also contributed to the data quality. Moreover, Brakenridge et al (2003Brakenridge et al ( , 2005Brakenridge et al ( , 2012 have discussed that the frequent temporal sampling of satellite-based observations and ground sources (media reporting) determines the accuracy level amongst the (non-)flood event candidates. The dataset covers flood events at the global scale from 1 January 1985 to present.…”

“…These methods make use of: (a) reflected solar radiation [3,14]; (b) emitted thermal radiation [15]; and (c) microwave backscatter and/or emission [11,16]. Reflected solar radiation methods are effective for assessing seasonal patterns of inundation in areas that have minimum vegetation and cloud cover [4,17].…”
