How to use OpenWeatherMap UV Index
Thank you to Francesco Azzola for the article:
This post describes how to use OpenWeatherMap UV Index. This is an interesting API because we can use it to explore some important aspects of Android and of location-aware APIs. OpenWeatherMap provides this API for free! As you may already know, OpenWeatherMap also provides a full set of APIs about weather information: you can get current weather conditions, forecast, historical information and so on. This information is free, and we can use OpenWeatherMap APIs free of charge.
At the end of this article, we will build an Android app that gets the UV index and shows it using Material Design guidelines.
Before diving into the details of the app, it is useful to have some idea about the UV index.

OpenWeatherMap presents the release of the VANE Language service
OpenWeatherMap presents the release of a new service – VANE Language (formerly Imagery API) – with examples here: http://owm.io/vaneLanguage.
We initially called this service the “Imagery API”, but later realised that it consists of much more than just API calls. “VANE Language” is a more appropriate name for it, as it is like an SQL for satellite images. It is a unique offering in the satellite market. VANE Language is an entirely online service – there are no manual procedures, or presets such as maps prepared in advance.
Each “image” that we receive from Landsat 8 is not an image as commonly understood, but several layers that have to be processed and merged in some way before you can do anything with them. Each unarchived number of bands occupies around 2 GB of storage, and it obviously takes a lot of resources and time to process it. For example, to create a global map you need around 10,000 images that need to be processed and merged.
With VANE Language, the developer does not worry about time-costly pre-processing, because we do it all online immediately. We provide a powerful tool that will be familiar to any developer and hides all the complexity. In short, VANE Language gives full flexibility for a developer to do whatever they want with images and deploy the results into applications.
It also has a unique feature: configuring the formula for image processing. This allows the developer to set up their image-processing logic to create specific vegetation indexes, false colours and any other images that they want to use for analysis of objects, changes, yield health, etc.

Map Editor 2.0: Map with bike routes
There are many online map services for those who prefer active leisure. For example, here is a map with bike routes: http://www.thunderforest.com/maps/opencyclemap/.
Route maps are extremely useful! Also, while choosing a route it would be beneficial to know the weather in the region you will be travelling in. And what if we combine a bike route map with weather data from OpenWeatherMap? Eureka!
Map Editor 2.0 can help us with that!

Air pollution: ways to forecast and calculate it
In recent years, the fight against air pollution has become global. Humanity, at least when we are speaking about developed countries, starts to realize finally that the Earth is our common home which can get not suitable for living in the near future. Atmospheric pollution takes place when substances harmful for living creatures diffuse throughout the surrounding air, and then this destructive activity has its toxic impact later since it causes global changes of climate of the Earth.

New air pollution APIs
Taking into account the great importance of the climate change issue, we at OpenWeatherMap would like to make our own contribution to making this world a better place.
We hope that the air condition data, both current and historical, will give you a great opportunity to create a variety of new applications and analytic services to keep an eye on what we breathe in real time and whether there is any improvement over time.
