TEMIS aims to compute and deliver global concentrations of tropospheric trace gases, and aerosol and UV products derived from observations of nadir-viewing satellite instruments such as GOME, SCIAMACHY and (A)ATSR. TEMIS is part of the Data User Programme (DUP) of the European Space Agency (ESA). The service of TEMIS centres around the four themes.

The data products within each of the services are listed and linked to at the TEMIS home page.

The following table provides a list of the main product groups and gives links to brief product introductions.

Initially, the TEMIS project also contained the following data products, intended to be retrieved from measurments of the SCIAMACHY instrument. Due to lacking quality and to delays in the delivery of the data, these products have been removed from the TEMIS project. For completeness, the brief product introductions have been retained.
