Global Daily Air Temperature at 1 km Resolution for 2020

2020 daily maximum and minimum near-surface air temperature data at a 1 km resolution for the global land area between 50°S and 79°N. The dataset was generated by Yuyu Zhou using a seamless land surface temperature dataset, a digital elevation model, weather station observations, and a spatially varying coefficient model with sign preservation algorithm. It is a 104.4 GB TAR file published under a CC-BY-4.0 license.

Use Cases

• Modeling urban heat island effects based on high-resolution global temperature data.
• Conducting climate change impact studies based on daily maximum and minimum temperature grids.
• Hydrological modeling requiring spatially detailed air temperature inputs.
• Validating and downscaling coarser climate model outputs based on the 1 km resolution product.

Strengths

• 104.4 GB dataset indicating a large volume of high-resolution data.
• 1 km spatial resolution for detailed global analysis.
• Covers the global land area from 50°S to 79°N.
• Includes both daily maximum and minimum temperature variables.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Documentation is referenced as being with the 2003 data, which may require separate location.
