Observation uncertainty in data assimilation

By Sarah Dance Approximately 4 million properties in the UK are at risk from surface-water flooding which occurs when heavy rainfall overwhelms the drainage capacity of the local area. Several national weather centres have been developing new numerical forecasting systems … Continue reading

Geoengineering – how could we detect its cooling effect?

By Eunice Lo Sulphate aerosol injection (SAI) is one of the geoengineering proposals that aim to reduce future surface temperature rise in case ambitious carbon dioxide mitigation targets cannot be met.  Climate model simulations suggest that by injecting 5 Tg of sulphur dioxide gas … Continue reading
