Session: Science I: Climate data records for understanding the causes of global and regional sea level variability and change

Presentation type: Type Forum

In the framework of the European Long Term Data Preservation Program (LTDP+) which aims at generating innovative Earth system data records named Fundamental Data Records (basically level 1 altimeter and radiometer data) and Thematic Data Records (basically level 2+ geophysical products), ESA/ESRIN has launched a reprocessing activity of ERS-1, ERS-2 and ENVISAT altimeter and radiometer dataset. A large consortium of thematic experts has been formed to perform these activities which are 1) to define products including the long, harmonized record of uncertainty-quantified observations, 2) to define the most appropriate level 1 and level 2 processing, 3) to reprocess the whole times series according to the predefined processing and, 4) to validate the different products and provide them to large communities of users focused on the observation of the atmosphere, ocean, coastal, hydrology, sea ice, ice sheet regions.
The objective of this talk is to inform the OSTST members of this initiative and to explain the main guidelines, constraints and status of the project.
