AUTHIST - Historical gridded monthly climate data for Austria

The long-term historical gridded dataset HistAlp provides homogenized instrumental data from 1780-2014 with a 5’ x 5’ spatial resolution and monthly timesteps, for the domain of the European Alps. (Auer et al., 2007) Data available here: https://data.hub.geosphere.at/group/histalp The gridded observational dataset SPARTACUS is available for Austria and some adjacent regions in neighboring countries with a spatial resolution of 1×1 km and a daily temporal resolution from 1961-2020. (Hiebl and Frei, 2016). Data available here: https://data.hub.geosphere.at/dataset/spartacus-v2-1d-1km Both datasets were combined by regridding the lower-resolution HistAlp data to the SPARTACUS grid, and adjusting the mean bias of HistAlp to SPARTACUS based on monthly climatologies of the period 1961-2014 on each grid cell. The original variability and trends of HistAlp are retained with this method. The dataset provides bias-adjusted HistAlp data for the period 1780-1960 (temperature) and 1801-1960 (precipitation), and from 1961 to 2024 unmodified SPARTACUS data is used.
