Historical satellite data are of high value for climate research as an independent source to validate the output of climate models. Of special interest are data from the AVHRR sensor in 1km spatial resolution (LAC), which are available from 1981 until 2017 (2022). The data archived at different centers in Europe need consolidation (filling data gaps, removing redundant orbits etc.) and harmonization (generating the same format and meta-files) before transferred to ESA facilities to make a long time series accessible for scientific use. In the frame of ESA's Long Term Data Preservation program the archived AVHRR data will be stored and maintained for the next +50 years. We will present the different parts of the ESA-UniBern AVHRR-LTDP project and recommendations for the next processing steps needed to generate essential climate variables (e.g. snow extent, lake surface water temperature).
