A new service for the comparison of weather data

A new service for the comparison of weather data

This is interesting service where you can compare using the graphs provided the weather from various weather providers in some major cities. http://weatherchecker.org/

This is very interesting, because sometimes when you watch the weather forecasts from different companies it’s discouraging that they are quite different from each other. And it’s not clear whom to believe to. This is especially annoying when planning long trips, when you need to bring a raincoat, warm sweater and waterproof shoes when focusing on one provider, and if you focus on the other - the sunscreen and sunglasses. It still shows few cities and compares weather for today and few past days, but it is enough to have overall high-level picture.

To be able to see and compare the weather you can choose from drop-down list the city and the desired dates.

How satellite vessel monitoring system OWM AIS helps to analyse marine traffic

How satellite vessel monitoring system OWM AIS helps to analyse marine traffic

Company OpenWeatherMap - provider of global satellite and weather data, presents a number of research products for monitoring ship traffic OWM AIS. This is simple and user-friendly developer API and display of current and historical information on interactive maps. OWM AIS provides global coverage, our technology allows you to track the ship, not only along the coast, but also in the open ocean. The data is supplied by commercial satellite SpaceQuest, Ltd.

Density Map of Automatic Identification System (AIS)

Density Map of Automatic Identification System (AIS)

Our new Density Map of Automatic Identification System (AIS) data is an interactive online map to watch intensity of global vessel traffic or check marine activity in any area of your interest.

By zoom-in you can get more details in any ocean, harbour, along any river and our map will be rendered in seconds. You can filter by month or even a year to get a bigger picture. Also is it possible to filter by type of vessel or group of them to get more specific reports about fishing activity, for example.

Our Big Data platform processes enormous number of data online to make such interactivity possible. Instead of traditional static repots you get much more flexible tool for marine traffic analysis.

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.

OpenWeatherMap: Big Data on guard of your health. Vitamin D and ultraviolet radiation

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.
