ClimaLab

Develop a climate exploration and creation mobile application named ClimaLab, comprising three core interactive functional modules aligned with precise technical and functional specifications. First, build the Globe module: integrate a live Three.js-rendered 3D Earth model, sync real-time NASA EONET data feeds to dynamically display global extreme weather event markers, and implement a real-time calculation module to render an accurate day/night terminator line that updates continuously based on real-world solar position. Second, develop the Predict module: support user input of any city, output climate projection data covering five core hazards including heat, rainfall, drought, coastal risk and fire weather, the projection data must cover three standard IPCC emissions scenarios and four distinct time windows spanning up to the year 2080, all underlying data sources are strictly limited to ERA5 reanalysis datasets and CMIP6 HighResMIP ensemble model outputs to ensure data consistency and scientific validity. Third, implement the Create module: enable users to convert any selected city's climate projection results into shareable content, provide four pre-designed templates supporting 9:16 and 1:1 two aspect ratios for postcard generation, and integrate a built-in AI module to generate customized city-specific climate preparedness action plans corresponding to the projection results for each postcard. The entire application eliminates mandatory user account registration and login requirements, all core exploration functions are accessible directly upon app launch to lower user access threshold, all module interactions are designed to be smooth, intuitive and responsive, ensuring a seamless user experience across common mobile device models.
