Weather APIs, powered by technology, provide weather data (some real-time, some at specific times). These data can influence personal decisions and business decisions. There are also numerous APIs that offer Air Quality information. Each with their own features which makes one better than the other.

Air Quality APIs are used to measure carbon monoxide, air pollution, and air quality index. They help retrieve currently forecasted, and historical data. Individuals and enterprises can then use this data for all sorts of decisions, including travel arrangements or health-related choices.

In this article, we’ll be exploring the best 6 Weather APIs that provide services for measuring Air Quality.

ClimaCell

The ClimaCell Weather API gives real-time and historical information about the weather. The API exposes air quality data, pollen data, and fire index data from all around the world.

With ClimaCell’s Air Quality API, developers can get a good number of useful data which includes health recommendations, percentage of Carbon Monoxide(CO), Nitrogen Dioxide(NO2), and Sulfur Dioxide(S02) in the air, global AQ index, and others.

ClimaCell works by comparing historical air data and real-time data to forecast predictions of the future air condition. This helps in providing the right information and helping businesses make better decisions.

ClimaCell has a free plan which allows developers to make 1,000 calls per day, 100 calls per hour and provides a free sample of the air quality and pollen layer. Other plans support multiple API calls and more features that influence business decisions.

Breezometer

Breezometer is an API service that provides weather data such as wind speed, humidity, precipitation, and air quality with coverage of 95 countries worldwide.

Breezometer has the following features:

  1. The data is updated hourly, so you’re sure not to be provided vague or expired data.
  2. It provides a 4-day forecast.
  3. It provides APIs which range from air pollution to wildfires to pollen reports.

Breezometer offers free and paid plans. While the free plan is limited to 1,000 calls per day, applications using the paid plans can make millions of calls per day and they also get other features like health recommendation, Pollen Counts and Pollen Heatmap.

Visual Crossing Weather API

The Visual Crossing Weather API offers historical and realtime weather services. All plans come with long-range and worldwide coverage. It provides hourly and daily detailed forecasts in CSV, JSON and OData. It also makes use of leading weather models.

Visual Crossing Weather offers both free, affordable and enterprise paid plans.

Features of Visual Crossing Weather API:

  1. It provides 15-day forecast data
  2. It provides historical data summarized by month, year and may other categorizations
  3. Delivers history weather history in JSON (which is also available in the free plan)

AirVisual

AirVisual API provides global air quality data services through its large network of air sensors. The data provided goes through different validations made by machine learning and artificial intelligence to ensure accurate and reliable data.

The features of AirVisual include:

  1. Real-time Air Quality Index
  2. Real-time weather data, station name and coordinate.
  3. 7-day forecast and 48hr historical data.

The free plan is limited to 10,000 API calls per month which can be increased to 10 million calls by upgrading to the highest available plan.

Getting started with the API involves creating an AirVisual account, creating your API key, and using the docs to integrate the API into your application.

Weatherbit

The Weatherbit Air Quality API returns worldwide data on the 6 major surface pollutants, including PM 2.5, PM 10, CO, SO2, NO2, and O3. You can also access air quality index score (AQI) data as well as pollen levels.

Here’s an example JSON response for a city in the US:

Weatherbit offers plans that cost as low as 0 dollars per month to others that cost as high as 470 dollars per month. The free plan is limited to 500 calls per day and other advanced plans can be used to make up to 5 million calls per day.

Plume API

Plume combines machine learning and atmospheric sciences to create API services powered with AI for delivering live and forecast pollution data. The service monitors atmospheric data to evaluate the influence on pollution levels in different locations.

The major features are:

  1. Integration with devices to easily discover pollution data in an environment.
  2. AI algorithms and atmospheric models which delivers hourly forecasts of data gathered for geographical features.

Plume offers different premium plans that users can get started with based on their needs and budget. Although they’re quite expensive (starting at USD 499 per month), they provide information on weather from an earth view to street view and also provide accurate data on common air pollutants and their absolute concentration levels.

Conclusion

In this article, we have looked at the best six APIs for determining weather information worldwide. Each of these APIs has different plans and features which makes them better than the other. This article should help you make effective choices when having to deal with weather data that concerns air quality and pollution.
