Sentinel-4 Level 2 Product User Manual (PUM) UV Aerosol Index

A number of geophysical (Level 2) products are derived from Sentinel-4. The retrieval algorithms are described in an Algorithm Theoretical Basis Document (ATBD) and the corresponding product formats are described in a Product User Manual (PUM). This document, describes the technical characteristics of the Sentinel-4 Level 2 UV Aerosol Index product. Despite the ECSS standard does not strictly require the provision of the PUM along space engineering software, this deliverable is certainly handy for the end-user of the L2 product as seen in previous missions such as GOME, GOME2 and S5p
