Ensemble Mean Reanalysis Soil Temperature Dataset at 1 degree latitude/longitude resolution (60 South to 90 North), 1981 - 2018.

This dataset accompanies Herrington, T., Fletcher, C. and Kropp, H. (in Review). The Cryosphere. It is a 1 degree ensemble mean soil temperature of the 8 reanalysis and LDAS products (based on CFSR, ERA5, ERA5-Land, ERA-Interim, GLDAS-CLSM, GLDAS-Noah, JRA-55 and MERRA2), averaged over the near surface (0 - 30 centimeter, cm) and at depth (30 cm - 300 cm), between 1981-2018. All reanalysis products were remapped using a conservative remapping technique to a resolution of 1 degree latitude and longitude, based on the GLDAS-CLSM land-mask. The ensemble mean is calculated as a simple arithmetic mean of all eight products at each timestep for all grid cells that include valid soil temperature measurements for all 8 products.

本数据集配套于Herrington T、Fletcher C与Kropp H合著的待刊论文，发表期刊为《The Cryosphere》（冰冻圈）。本数据集包含8种再分析资料与陆面数据同化系统（Land Data Assimilation System, LDAS）产品的1°分辨率集合平均土壤温度数据，所用产品包括CFSR、ERA5、ERA5-Land、ERA-Interim、GLDAS-CLSM、GLDAS-Noah、JRA-55及MERRA2；数据时段为1981-2018年，分别针对近地表（0~30厘米，cm）与深层（30厘米~300厘米）土层进行平均。所有再分析资料均基于GLDAS-CLSM陆面掩码，通过保守重映射方法重投影至1°经纬度分辨率。对于所有8种产品均具备有效土壤温度观测值的网格单元，集合平均通过对每个时间步长下的8种产品取简单算术平均计算得到。
