Despite the developments in the global modelling of chemistry and of the parameterization of the physical processes, carbon monoxide (CO) concentrations remain underestimated during Northern Hemisphere (NH) winter by most state-of-the-art chemistry transport models.The consequential model bias can in principle originate from either an underestimati
Abstract Background The coronavirus disease 2019 pandemic has had a serious impact on global mental health, particularly in intensive care unit survivors.Given the lethal potential and unpredictability of coronavirus disease 2019, a high risk of posttraumatic stress disorder was identified in the beginning of the crisis.There are insufficient detai
Abstract Background Calculating the greenhouse gas savings that may be attributed to biofuels is problematic because production systems are inherently complex and methods used to quantify savings are subjective.Differing approaches and interpretations have fuelled a debate about the environmental merit of biofuels, and consequently about the level
