Projects

• SUPER - SUb-daily Precipitation Extremes in highly-populated Regions The main objective of SUPER is to quantify the influence of anthropogenic activity on sub-daily extreme precipitation in highly populated regions
• Sensible heat has significantly affected the global hydrological cycle over the historical period Multiple lines of evidence indicate widespread changes to the global water cycle since 1950. Here we show, using a range of climate modelling results, that changes in sensible heat are the dominant contributor to the present global-mean precipitation change since preindustrial time.
• The NetBC project Black carbon: A challenging piece of the climate puzzle
• AC/BC In search of airborne soot, and how it affects the climate
