What is Flood Mapping with Passive Microwave Remote Sensing: Current Capabilities and Directions for Future Development about?

Passive microwave remote sensing involves the measurement of earth-emitted thermal radiation at frequencies from 1 to 100 GHz. Flood mapping with microwave radiometry is possible through the strong effect that surface water has on microwave emissivity in otherwise dry areas. The near transparency of clouds over much of the spectrum makes microwave sensing one of the few ways that flooding can be observed from space day or night irrespective of cloud cover. This chapter explains the physical basis for microwave remote sensing of floods, how competing factors reduce sensitivity to flooding or trigger false positives, and how current retrieval methods approach these challenges. Recent algorithm development efforts have focused on maximizing flood detection probability and arriving at flooded fraction estimates while mitigating error sources. Existing algorithms are also capable of downscaling sensor footprint average flooded fraction to produce higher-resolution flood maps. The chapter demonstrates new algorithm approaches likely to further improve flood mapping accuracy and usability in a variety of applications.
