Weather is part of our everyday lives. Who doesn’t check the rain radar before heading out, or the weather forecast when planning a weekend away? But where does this data come from, and what is it made of? The answer is a mix of measurements, models and statistics, meaning that the use of weather and climate data can get complex very quickly.
This session provides a brief overview of the science behind weather and climate forecasts and provides you with the tools to get started with weather data – even if you aren’t a meteorologist. Learn how to connect weather data to other data sources, how to visualize weather and climate data in an interactive weather dashboard embedded in a Python notebook, and other ways you can use weather data for yourself, from examples using weather APIs, maps, PixieDust and Machine Learning.
