Why was it particularly important to measure levels of Aerosols during the COVID-19 pandemic? | Because of the health impacts of aerosols which can deeply penetrate into human lungs and cause serious respiratory problems, which could then potentially increase the number of severe cases of COVID-19 |
Did aerosol optical depth (AOD) observed over Northern Italy after the implementation of COVID lockdown, increase or decrease? | Increase |
Did in situ ground-based measurements of NO2 in Europe match up with the satellite data in the ICOVAC study? | Yes |
Why did concentrations of secondary pollutants such as ozone increase in some regions during COVID lockdowns? | Because of the reductions in NOx |
What is the difference between weather and climate? | Climate is the average weather over long periods |
What could changing regional climates alter? | Changing regional climates could alter forests, crop yields and water supply. |
What are the three key services provided by C3S? | The three key services provided by C3S are the Climate Data Store (CDS), data in action and climate bulletins. |
What are the five data product types available on the C3S Climate Data Store? | The five data product types available on the C3S Climate Data Store are reanalysis, climate projections, satellite observations, climate indices, and seasonal forecasts. |
Excluding observations from satellite and in situ monitoring systems, what are the other sources of climate data in the C3S CDS? | Seasonal predictions, climate reanalysis and climate projections |
What is ERA5 data? | Historical observations into global estimates using advanced modelling and data assimilation systems. |
What are climate projections? | Simulations on the climate until the end of the century |
What are the C3S Climate Data Store Applications? | Pre-built interactive visualisations of the data |
What does the Copernicus C3S Toolbox enable users to do? | Develop custom-made applications using the Python programming language. |
