EM-Earth

The Ensemble Meteorological Dataset for Planet Earth (EM-Earth) offers a comprehensive collection of meteorological data for global land areas. It includes crucial variables such as precipitation, mean air temperature, air temperature range, and dew-point temperature. The dataset provides high-resolution coverage at 0.1° spatial resolution, spanning from 1950 to 2019. This extensive temporal and spatial coverage makes it valuable for various research and application domains.

EM-Earth distinguishes itself by offering both hourly/daily deterministic estimates and daily probabilistic estimates through 25 ensemble members. This dual approach caters to a wide range of hydrometeorological applications, allowing users to choose the appropriate data type based on their specific needs for accuracy and uncertainty assessment. The dataset is managed by Computational Hydrology at the University of Saskatchewan and is available under a Creative Commons Attribution 4.0 International (CC BY 4.0) License.

Key features include its detailed documentation, provided via a DOI, and specific citation instructions to ensure proper attribution. The data is discoverable on the Registry of Open Data on AWS, highlighting its accessibility and integration within a major cloud platform. Example publications demonstrate its utility in scientific research, reinforcing its credibility and practical application.
