OpenWeatherMap

OpenWeatherMap is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand OpenWeatherMap rather than just read about it. In short: OpenWeatherMap is an online service, owned by OpenWeather Ltd, that provides global weather data via API, including current weather data, forecasts, nowcasts, and historical weather data. The company provides a minute-by-minute hyperlocal precipitation forecast.

Key takeaways

OpenWeatherMap belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect OpenWeatherMap to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of OpenWeatherMap from memory before moving on to harder problems.

Reference excerpt

OpenWeatherMap is an online service, owned by OpenWeather Ltd, that provides global weather data via API, including current weather data, forecasts, nowcasts, and historical weather data. The company provides a minute-by-minute hyperlocal precipitation forecast. The convolutional machine learning model uses meteorological broadcast services and data from airport weather stations, on-ground radar stations, weather satellites, remote sensing satellites, METAR, and automated weather stations. The company has more than 2 million customers, ranging from independent developers to Fortune 500 companies. The APIs provided by OpenWeatherMap have resulted in repositories on GitHub. The APIs support multiple languages, units of measurement, and industry standard data formats like JSON and XML.

Company Profile OpenWeather Ltd is a UK-based company that provides global environmental data using artificial intelligence and machine learning. At 2022 it served more than six million users. They deliver more than two billion forecasts each day and their products are specialized for energy, logistics, agriculture, and other industries. OpenWeather works with organizations like the Met Office and the U.S. National Oceanic and Atmospheric Administration. They are members of both the World Meteorological Organization and the European Space Agency. The company also runs the OpenWeather Foundation, which supports open data access, education, and sustainability efforts.

Products and services OpenWeatherMap provides weather maps, weather alert services, and weather data. The length of the nowcast reaches 2 hours, the short-term forecast reaches 16 days, and the long-term forecast can reach up to 1 year. Historical weather data goes over 40 years. In 2015, Google chose OpenWeatherMap as a weather data provider for its bid-by-weather script in Google Ads, which serves the ads based on the local weather conditions, such as temperature, humidity, and cloudiness. In the same year, Google published documentation on how to use OpenWeather data to display weather conditions on Google Maps. In 2020, Samsung included OpenWeatherMap into their Galaxy Watch Studio as weather data for the Galaxy Watch. In 2020, OpenWeatherMap released its weather application for iOS and Android. OpenWeather provides data for weather risk management on an individual agreement basis. OpenWeather also operates under a Creative Commons Attribution-Share Alike license, providing free access to the APIs that include current weather, a minutely forecast for 1-hour, short-term history, weather maps, alerts, geocoding, air quality weather triggers, and weather widgets.

Worked examples

Example 1 — a first encounter with OpenWeatherMap

Start with the simplest possible case. Write down what OpenWeatherMap claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to OpenWeatherMap before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about OpenWeatherMap ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of OpenWeatherMap

In research: OpenWeatherMap appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses OpenWeatherMap in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: OpenWeatherMap is common in secondary-school and first-year university syllabi. It links to neighbouring topics Meteorological companies, Meteorological data and networks, so understanding it makes those chapters shorter.
In everyday life: Look for OpenWeatherMap outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is OpenWeatherMap in simple terms?

Why does OpenWeatherMap matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study OpenWeatherMap?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
