Global Daily Air Temperature at 1 km Resolution for 2020

104.8 GB of gridded daily maximum and minimum near-surface air temperature data covering 50°S to 79°N. The dataset was generated by Yuyu Zhou using a seamless land surface temperature dataset, a digital elevation model, and weather station observations with a specialized algorithm. It is intended for global studies in urban, climate, and hydrological research.

Use Cases

• Modeling urban heat island effects based on high-resolution global temperature data.
• Analyzing climate change impacts on a local scale based on daily maximum and minimum temperature grids.
• Calibrating hydrological models based on near-surface air temperature inputs.
• Conducting global environmental studies based on the 1 km resolution synthetic temperature product.

Strengths

• Global coverage from 50°S to 79°N.
• High spatial resolution of 1 kilometer.
• Large dataset size of 104.8 GB, indicating detailed coverage.
• Includes both daily maximum and minimum temperature values.

Limitations

• Documentation is referenced as being with the 2003 data, which may require extra effort to locate.
• The dataset is for a single year (2020), limiting longitudinal analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
