Name
A Reanalysis (ModE-RA) and a medium-size AGCM ensemble (ModE-Sim) to study climate variability in the modern era (1420 to 2009)
Description
ModE is the output of the PALAEO-RA project hosted at the Oeschger Centre for Climate Change Research between 2018 to 2023, funded by the European Research Council through the H2020 program (ERC Grant PALAEO-RA 787574).
The aim of PALAEO-RA was to create a monthly, 3-dimensional climate reconstruction of the past 600 years. Therefore sparse information on historical climate (including early instrumental data, documentary data, and proxy data) of that period were combined with additional physical constraints taken from a large ensemble of simulations with a state-of-the-art atmospheric general circulation model by using an offline data assimilation technique. For more information on the project, visit https://www.palaeo-ra.unibe.ch/.
The project output provided here consists of two main products and an additional sensitivity experiment:
• ModE-RA, the main reanalysis product,
• ModE-Sim, the original AGCM ensemble prior to data assimilation.
• ModE-RAclim, a version of the reanalysis product based on an alternative (experimental) covariance estimation (see experiment description for details).
While ModE-RA should be the version used for regular analysis, ModE-RAclim should be more seen as a side product only to be used for sensitivity studies.
