In the age of climate emergencies and ecological crises, understanding the nuances of climate data has never been more critical.
Researchers, policymakers, and environmental enthusiasts alike are turning to advanced tools for insights into climate patterns. One such powerful tool is Google Earth Engine (GEE), a cloud-based platform for planetary-scale environmental data analysis.
GEE provides an extensive catalog of geospatial datasets, along with a robust framework for data processing and visualization. As the need for actionable insights grows, so does the demand for tutorials that make complex data comprehensible.
In this article, we explore 12 free Google Earth Engine tutorials focused on climate data analysis. Each tutorial serves as a standalone resource, yet they collectively provide a comprehensive foundation for analyzing climate variables like precipitation, temperature, and drought conditions.
Credit goes to Amirhossein Ahrari for curating these valuable resources.
