Scientists discover urea in atmosphere, revealing profound consequences for climate
Observations of urea and other selected trace gasses indicate biomass-burning inputs of urea to the marine environment. An example time series of urea concentrations is shown with the trace gasses ozone (O3), carbon monoxide (CO), hydrogen cyanide (HCN), and nitrogen oxides (NOx) for a flight in the Cape Verde region in February 2020. (A) The blue shaded region indicates enhancement of urea at the sea surface due to biogenic sources. The gray shaded…
