The measures taken to contain the spread of COVID-19 in 2020 included restrictions of people's mobility and reductions in economic activities. These drastic changes in daily life, enforced through national lockdowns, led to abrupt reductions of anthropogenic CO2 emissions in urbanized areas all over the world. To examine the effect of social restri...

Most of the effects caused by fog are negative for humans. Yet, numerical weather prediction (NWP) models still have problems to simulate fog properly, especially in operational forecasts. In the case of radiation fog, this is partially caused by the large sensitivity to many aspects, such as the synoptic and local conditions, the near-surface turb...

The temperature is rising due to climate change, resulting in more heat waves and more hot days and nights. All government agencies (municipalities, provincial governments and water boards) in the Netherlands must therefore identify the bottlenecks relating to flooding, heat, drought and floods before 2020.
