- | * Description: Starting from the level 1 UV product, spike and temperature corrections are applied to the irradiances. The spike correction is always applied if needed. An operative UV configuration with the [[devel:eubrewnetconfiguration&#temperature | Temperature correction data]] must be available for the requested period. Output data is further filtered by the [[devel:eubrewnetconfiguration&#exclusion_list | UV Exclusion List]] | + | * Description: Starting from the level 1 UV product, spike and temperature corrections are applied to the irradiances. The spike correction is always applied if needed. For the temperature correction, an operative UV configuration with the [[devel:eubrewnetconfiguration&#temperature | Temperature correction coefficients]] must be available for the requested period. Output data is further filtered by the [[devel:eubrewnetconfiguration&#exclusion_list | UV Exclusion List]] |

As of 2022-06-22, the output irradiances are calculated using the same generic slit function for all Brewer instruments. Output data is further filtered by SHICRIVM's QA/QC, retaining only measurements with GREEN and YELLOW flags. As in the case of level 1.5, output data is further filtered by the [[devel:eubrewnetconfiguration&#exclusion_list | UV Exclusion List]] | + | * Description: Starting from the level 1.5 UV product, process the data using the [[https://www.rivm.nl/en/uv-ozone-layer-and-climate/shicrivm|SHICRIVM code]] developed by Harry Slaper at the [[https://www.rivm.nl/en|National Institute of Public Health and the Environment (RIVM)]].
