AERA5-Asia: Long-Term Asian Precipitation at 0.1° Hourly

Asia, spanning 60°E–150°E and 15°S–55°N, is covered by this long-term precipitation dataset. It combines the high spatiotemporal resolution of ERA5-Land with the quality control of the APHRODITE dataset. The data is provided as hourly GeoTIFF files at a 0.1-degree spatial resolution.

Use Cases

• Climate trend analysis based on the 65-year temporal coverage from 1951 to 2015.
• Hydrological modeling using the high-resolution 0.1-degree and hourly gridded precipitation data.
• Regional climate validation by comparing the merged product against local station data.
• Extreme weather event studies leveraging the continuous hourly time series.

Strengths

• Covers a long temporal period of 65 years (1951–2015).
• Offers high spatiotemporal resolution (0.1°, hourly).
• Merges two established data sources (ERA5-Land and APHRODITE) for potential quality improvement.
• Has a defined geographic scope covering the Asian landmass.

Limitations

• The exact data volume (file size, number of rows/grids) is not specified in the provided metadata.
• The dataset's availability is split across multiple Zenodo records, which may complicate access.
• Metadata on the last update date is missing, limiting assessment of freshness.
