ERA5 Geopotential Height Mapping Tool
ERA5 geopotential height maps at 850, 700, 500, 300 and 250 hPa are fundamental for analysing the three-dimensional structure of atmospheric circulation. These standard pressure levels represent key layers of the troposphere, from the lower troposphere to the upper-level jet stream, allowing the evolution of troughs, ridges, Rossby waves, and jet-stream patterns to be clearly visualized. Geopotential height fields are widely used for synoptic meteorology, severe weather analysis, atmospheric dynamics research, climate variability studies, aviation meteorology, and the interpretation of large-scale weather patterns. They are also invaluable for university teaching, scientific publications, and communicating atmospheric processes through clear, high-quality visualizations.
Create high-quality hourly ERA5 geopotential height maps and animations from pressure-level NetCDF files in just a few minutes, with extensive customization of colour palettes, geopotential height contours, map appearance, and export options.
Graphical interface for creating customizable ERA5 geopotential height maps and animations across five standard pressure levels.
Advanced Visualization
- Transform ERA5 geopotential height NetCDF datasets into high-resolution maps and animations with fully customizable visualization settings.
- Customize pressure level, geographic domain, time range, map titles, colour palettes, geopotential height contour lines, animation speed, and export formats, including PNG, PDF, GIF, and MP4.
