River flow monitoring with passive microwave radiometry and potential synergy with swot
IGARSS 2023 - 2023 IEEE INTERNATIONAL GEOSCIENCE AND REMOTE SENSING SYMPOSIUM(2023)
摘要
The global water cycle is accelerating in a changing climate. A key element of the hydrology cycle is surface streamflow, which lacks a global river gauging network with open data shared among international stakeholders. As an alternative, rivers have been monitored from space with multiple orbital sensors that continue providing river measurements worldwide for the past several decades and into the future. With its all-weather and day-and-night capabilities, passive microwave satellite sensors provide a unique data source for near-daily global streamflow monitoring.
