Simulated stable oxygen isotopic composition (δ18O) of precipitation from isotope-enabled GCMs (iGCMs) have gained significant visibility nowadays. This study evaluates bias correction techniques to reduce the systematic and dispersion biases modelled δ18O by ECHAM5-wiso model compared Global Network Isotopes in Precipitation (GNIP) observations over Central Europe. mean error (MBE) Root Mean S...

• It is found that the large-scale temperature anomalies for mid-Holocene (compared to preindustrial) are significantly different in low- and high-resolution versions For boreal winter, differences related circulation changes caused by response thermal forcing conjunction with orographic resolution. summer, shortwave cloud radiative emerges as predominant factor. The simulated (low versus high ...

Abstract. The acidity of atmospheric particulate matter regulates its mass, composition, and toxicity has important consequences for public health, ecosystems climate. Despite these broad impacts, the global distribution evolution aerosol particle are unknown. We used comprehensive multiphase chemistry–climate model EMAC (ECHAM5/MESSy Atmospheric Chemistry) to investigate main factors that cont...
