Frequently Asked Questions

Can I get historical weather data?

Yes. Many weather services publish historical records publicly. Extract past weather data to build climate datasets, training data for prediction models, or historical analysis databases.

How accurate is scraped weather data?

Data accuracy depends on the source. Target official meteorological services for the most reliable data. AlterLab extracts whatever the source publishes — no modification or interpolation.

Responsible Use

AlterLab is designed for extracting publicly available data. Always review the terms of service for any website you access, respect robots.txt directives, and ensure your use case complies with applicable laws in your jurisdiction.
