AUTHIST - Historical gridded monthly climate data for Austria
收藏资源简介：
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.

长期历史格点数据集HistAlp提供了覆盖欧洲阿尔卑斯山区的、1780-2014年的均一化仪器观测数据，其空间分辨率为5′×5′，时间步长为月尺度（Auer等，2007）。 可用数据链接：https://data.hub.geosphere.at/group/histalp 格点观测数据集SPARTACUS覆盖奥地利及周边邻国的部分区域，空间分辨率为1×1 km，时间分辨率为日尺度，时间范围为1961-2020年（Hiebl和Frei，2016）。 可用数据链接：https://data.hub.geosphere.at/dataset/spartacus-v2-1d-1km 本研究通过将低分辨率的HistAlp数据重网格化至SPARTACUS格网，并基于1961-2014年时段各格点的月尺度气候态，将HistAlp的平均偏差校正至匹配SPARTACUS。该方法保留了HistAlp原始的变率与趋势特征。本数据集提供两类校正后数据：1780-1960年的气温校正HistAlp数据，以及1801-1960年的降水校正HistAlp数据；1961-2024年则直接使用未做修正的SPARTACUS原始数据。 Auer, I., Böhm, R., Jurković, A., Lipa, W., Orlik, A., Potzmann, R., Schöner, W., Ungersböck, M., Matulla, C., Briffa, K., Jones, P., Efthymiadis, D., Brunetti, M., Nanni, T., Maugeri, M., Mercalli, L., Mestre, O., Moisselin, J.-M., Begert, M., 等.
