Evaluation of 20CR reanalysis data and model results based on historical (1930–1940) observations from Franz Josef Land

Abstract

This study was financially supported by the Helmholtz Climate Initiative REKLIM. Collecting, digitizing and analyzes of observational data were financially supported by the National Science Centre, Poland (Decision No. DEC--2012/07/B/ST10/04002). A work of Rajmund Przybylak was supported by the grant No. 2015/19/B/ST10/02933 funded by the National Science Centre, Poland. Klaus Dethloff and Annette Rinke acknowledge the support by the project Quantifying rapid climate change in the Arctic: Regional feedbacks and large-scale impacts (QUARCCS) funded by the German Federal Ministry of Education and Research (BMBF). We thank for the 20th Century Reanalysis v2 and v2c data, available at http://www.esrl.noaa.gov/psd/, provided by the NOAA/OAR/ESRL PSD, Boulder, Colorado, USA. Also, we are grateful for the provision of the PANGAEA archive, available at https://doi.pangaea.de/10.1594/PANGAEA.823609. The HIRHAM5 model simulation was conducted on the high performance computer “blizzard” of the German Climate Computing Center (DKRZ) and model data can be provided in case of request.
