AERA5-Asia: Hourly Asian Precipitation Data at 0.1° Resolution, 1951–2015

Asia is covered by this long-term precipitation dataset with 0.1-degree spatial and 1-hourly temporal resolution from 1951 to 2015. It was developed by researchers from Peking University in 2022 by combining the ERA5-Land and APHRODITE datasets. The data is provided in GeoTIFF format for land areas between 60°E–150°E and 15°S–55°N.

Use Cases

• Modeling long-term precipitation trends across Asia based on the 65-year time series.
• Analyzing hourly precipitation variability based on the 1-hour temporal resolution.
• Calibrating regional climate models based on the high-quality APHRODITE-anchored data.
• Studying spatial precipitation patterns based on the 0.1-degree grid resolution.

Strengths

• 65 years of temporal coverage from 1951 to 2015.
• High spatiotemporal resolution of 0.1 degrees and 1 hour.
• Combines the continuity of ERA5-Land with the quality control of APHRODITE data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness is unverified as the last update date is unknown.
