Big Data and analytical systems. OpenWeatherMap data on air pollution for exact forecasts

In recent years, the situation with air pollution is becoming more alarming and attracted the attention of leading media and politicians at the highest level. This is especially true of large cities such as Beijing, Los Angeles, Mexico City, Tehran, Johannesburg and other densely populated settlements, which are under the influence of various risk factors, such as dense traffic, the presence of air polluting enterprises located poorly in terms of ecology, where pollution levels sometimes exceed all standards many times.

Monitoring of marine traffic

Monitoring of marine traffic

If you are interested in monitoring of marine traffic in the specific zone or need to investigate what happened in the zone on the specific date then our new polygon API to satellite Automatic Identification System (AIS) might be helpful for you. The API returns current or historical information about vessels for any polygon on the global map. The polygon may have very complicated shape accurately replicating the outline of any port or harbour and extracting unnecessary zones inside.

Vitamin D and ultraviolet radiation. Myths and Reality

Vitamin D and ultraviolet radiation. Myths and Reality

And in the dark and cold winter months, when so little of the sun and all sorts of colds and viruses diseases await around every corner, and in the hot and sunny summer, when it is so easy to burn in the scorching sun, the most important factor for the maintenance of immunity is a high level of vitamin D in the body, which depends on the amount of ultraviolet radiation received. On this subject numerous studies have been conducted, which often contradict with the data, once considered immutable fact and the resulting recommendations are often diametrically opposed to those given earlier. You've probably seen some vague guidelines, such as the recommendation to be in the sun, "a few minutes every day." But these recommendations are too general to be useful. The amount of the sunlight, which is necessary to satisfy the requirement for vitamin D varies greatly depending on your location, skin type, season, time of day, and even atmospheric conditions.

How much of sunlight is sufficient for vitamin D generation? More than commonly believed. According to recent studies, at least 50% of the world population has deficit in vitamin D. People who live in areas with a small number of sunny days per year and / or a high degree of air pollution are at increased risk of getting vitamin D deficiency and its related diseases. A growing number of studies indicates that vitamin D plays an important role in the prevention of many diseases

Smog. The importance of accurate and timely data on air pollution

Smog. The importance of accurate and timely data on air pollution

Word Smog (smoky mist) comes from the fusion of the English words «smoke» - smoke and «fog» - fog. Smog - one of the most common types of pollution that can be seen clearly. It is formed by the reaction of products of incomplete combustion of fossil fuel such as coal with water droplets in the fog. Usually among carbon contaminants are CO2, nitrogen dioxide, sulfur dioxide NO2 S02 and other elements, and their reaction with the water drops in the mist form corrosive acids. As a result of inhalation of smog there is a sensation of breathlessness and cramps in the throat, a drop of acid attacks the mucous membranes of the respiratory tract that can cause (or worsen), asthma, chronic bronchitis, emphysema, as well as eye irritation and decreased immunity, or death. This is the smog in December 1952 in London that killed at various data from 4000 to 6000, which led to the emergence of the first laws aimed at preserving the environment.

The process of air pollution has been going on not the first millennium, but never before had it been so intense like in recent decades.

The results did not keep us waiting; urban environmental issues (in Beijing for the second time in December a "red" level of anxiety is declared because of the smog), depletion of the ozone layer, which protects Earth's surface from the harmful for all living ultraviolet radiation, global warming, entailing an increase in global sea level, which can have catastrophic consequences for all mankind.

API for Global UV Index: how weather data protects you from UV radiation effects

API for Global UV Index: how weather data protects you from UV radiation effects

Global Ultraviolet index (UV index), a measure of UV radiation levels, was developed and recommended by the WHO as a way of warning the population about the dangers of UV rays on health, helping people understand the need to use sunscreen. Open Weather Map created quick and simple APIs, which developers can use to create a variety of easy-to-use applications that could be useful for both promotional and marketing media within the tourism industry as well as for individual travelers planning a trip to tropical destinations.

New air pollution APIs

New air pollution APIs

New air pollution APIs are going to be available via openweathermap.org in January 2016.

Taking into account great importance of climate change issue OpenWeatherMap would like to make their own contribution into making this world the better place. 

The first version of API includes several data sets: CO (carbon), NO2 (nitrogen dioxide), O3 (ozone), SO2 (sulfur dioxide). 

We hope that air condition data, current  and historical, give you a great opportunity to create variety of new applications and analytic services to keep an eye on what we breath in real time and if there any improvement over time. 

Details will follow soon.

UV-index. Environmental factors that influence the UV level

Sunburn is traditionally considered an indicator of the attractiveness and a symbol of good health. Small amounts of UV are beneficial for people and essential in the production of vitamin D and serotonin, which is responsible for mood and overall vitality.Prolonged human exposure to solar UV radiation may result in acute and chronic health effects on the skin, eye and immune system. Over the longer term, UV radiation induces degenerative changes in cells of the skin, fibrous tissue and blood vessels leading to premature skin aging, photodermatoses and actinic keratoses. In the most serious cases, skin cancer and cataracts can occur.
