An automatic system for near-real time flood extent and duration mapping based on multi-sensor satellite data

open access: yes, 2021
This chapter presents an automatic and operational system for near real-time mapping of flood extent and duration using multi-sensor satellite data. The system is based on four processing chains for the derivation of the flood extent from Sentinel-1 and ...

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Ready for the flood? Assessing the applicability of pluvial flood mapping based on the worst urban flood in Sweden

open access: yesClimate Services
Pluvial flood mapping is a common way to identify locations at risk of being flooded in connection with an extreme short-duration rainfall. As rainfall extremes are expected to intensify in a warmer climate, more and more cities and municipalities are ...
