The Aerosol Index (AI) is a well-established data product that has been calculated for several different satellite instruments spanning a period of nearly 40 years. The S5P/TROPOMI aerosol index is referred to as the Ultraviolet Aerosol Index (UVAI). The relatively simple calculation of the Aerosol Index is based on wavelength dependent changes in Rayleigh scattering in the UV spectral range where ozone absorption is very small. UVAI can also be calculated in the presence of clouds so that daily, global coverage is possible. This is ideal for tracking the evolution of episodic aerosol plumes from dust outbreaks, volcanic ash, and biomass burning.","keywords":"","publicationState":"working","dataPublishedTime":null,"doiPublishedTime":null,"updateFrequency":"","status":"ongoing","result_field":null,"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/7138/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/1/?format=json","nonGeographicFlag":false,"phenomena":[],"dataLineage":"Data collected and prepared by European Space Agency (ESA).
