How Changes in the Sea Level Influence Transport Logistics: The Future and Now

How Changes in the Sea Level Influence Transport Logistics: The Future and Now

All images used in this article were obtained by using a new technology called Cloudless, which was developed by the OpenWeatherMap company. This is a new, non-traditional approach to creating a low cloud cover of Earth using low and medium resolution satellite images. At the heart of this approach lie the principles used in processing Big Data and machine-learning algorithms.

One of the most important physical consequences of global warming is the rise in sea level. Right now, the sea level is rising slowly enough, but, according to forecasts, this process will accelerate over time. This will affect the livelihoods of many coastal regions that will experience flooding. This means that the sea transport network may be seriously affected.
Shoreline erosion and land loss rates will be critical for planning coastal infrastructure.

Most forecasts say that warming of our planet will continue and is likely to accelerate. Recent research shows that the oceans will rise from 2.5 to 6.5 feet (from 0.8 to 2 meters) by 2100, enough to submerge many cities on the US Eastern Seaboard. But long-term forecasts are not an exact science.
Historically there have been problems matching the changes observed with factors from different sources that supposedly contribute to this process.
At the moment, it has been established that changes in global sea levels are affected by three factors: melting of the polar ice caps and glaciers, thermal expansion of water due to warming of the seas and oceans, and local factors such as changes in marine currents and geological processes (land rising and subsidence) which overlap with the global trend.
Both with the polar icecaps and with the glaciers, the rise in air temperature causes increased melting of large ice cover.
For example, should the Greenland ice sheet alone melt, the sea level could rise by 7m.

OpenWeatherMap 2017: Results of the Year

OpenWeatherMap 2017: Results of the Year

So the, new year, 2018 has come, and it's time to sum up the results of the past year for our company, OpenWeatherMap (UK, US and Latvia), developers of one of the best weather APIs in the world.
A lot happened and much has changed.
During the year, our number of users grew from 600,000 to 1 million. We participated in the Startup Grind Global Conference in Silicon Valley where the team from OpenWeatherMap was named in the top 50 Startup Exhibitions of 2017. Our mature team was filled up with excellent professionals and wonderful people.
We did a lot of new things and qualitatively improved our current developments.
In 2017, we were pleased to present to you:

Weather data: API and Weather Maps

  • The Open Dashboard for Agricultural Monitoring
     can help give you an idea of the possible use for meteorological and satellite data in your agricultural applications.
  • Specially for the agriculture sector, we launched an API for accumulated temperature data and an API for accumulated precipitation data.
  • The Weather Historical Bulk service.
    Now you can simply choose a city (or several cities) and download an archive, which contains bulk file with the weather history up to 5 years - any day, week or even several years.
  • A new and improved version of an API for UV-index
     

    Throughout the entire year, we worked constantly on our history weather API. For this year, the amount of data supplied and speed to process that data increased significantly. Also, we made it possible to quickly upload data in a format that doesn’t require additional processing and can be understood by any user.
    Our Weather Maps app changed qualitatively.
    This year, we added the ability to switch the layers of weather and satellite maps, create various combinations with them, and connect them to mobile and web apps.

Satellite data: Vane platform

This year, we significantly improved our satellite platform. Our team undertook a huge amount of work and in June were able to present  a new version  of the satellite image processing  platform VANE.

Based on the Vane platform, we developed a new product called  Global Satellite Base Map, which uses visual tools and query language to generate a map from satellite images. The uniqueness of the product is that all data processing is done on the fly, and there are no presets or pre-made calculations. The user defines the parameters for a calculation and image processing and immediately receives a result for any territory. This capability was only possible thanks to Vane, our super powerful data processing platform.

We recently presented you with Query Builder, our new interface for the Vane platform. Now you can use this simple tool to create your own map in just a few seconds, and with just one click receive a completed link for display on your site or app using a web map library like Leaflet, Open Layer, Mapbox and Google Map.

We are grateful to everyone that worked with us for all this time. We thank you all your feedback and for not getting bored by our tech support.
We have a ton of plans for the coming year. Stay tuned, and you will see a lot of the new and interesting things to come. Subscribe to our Telegram Channel https://t.me/openweathermap and get news first about our updates and new products!

Cloudless: global cloudless composite coverage based on the VANE Platform

In the drawing is global coverage obtained between 06.01.2017 and 09.01.2017 using data from the MODIS spectroradiometer aboard KA Terra and Aqua.

The current cloudless coverage of the Earth by medium and low-resolution satellite images are an important element in the regional and global systems that monitor the territorial changes caused by natural and man-made factors. For example, assessing the damage inflicted by forest fires caused by deforestation, volcanic eruptions, flooding,etc. Also, such types of coverage are popular as the base layer for cartographic web services.

The main stages of creating such coverage are: the selection of images, expert as a rule, the masking of clouded areas, tonal adjustment of images taken at different times of the year, and pasting them into single coverage using so-called “cutlines” which enable, to a certain extent, the joins between the pasted images to be hidden. Such operations, as a rule, are carried out in semi-automatic mode and require specialized software and highly qualified experts, which substantially increases both the time taken to create such a product and its cost.

The Weather and Sea Transport. Using Forecasts and Weather Maps for Effective Route Planning

The Weather and Sea Transport. Using Forecasts and Weather Maps for Effective Route Planning

It isn’t possible to affect weather conditions, but what is possible is to predict them.
Services currently available provide not only accurate up-to-date weather reports, and forecasts for different time-periods, but they also provide visual displays of various weather phenomena on weather maps, allowing a quick assessment of the overall picture. For such a weather-dependent industry as sea transportation, receiving timely accurate and visual information is particularly important.

Sea transport is one of the most tried and trusted ways of delivering cargo. Shipping lanes don’t need rebuilding or to be kept in working order. This is precisely why sea freight doesn’t cost as much as other modes of transportation.
Its main disadvantages are the long delivery time and the dependence of the vessel on weather conditions.
The most important meteorological variables which determine sailing conditions for sea vessels are the wind and those things which are dependent upon it: the condition of the water’s surface, precipitation, and temperature.

How Weather Forecasts Can Help Save Fuel.

How Weather Forecasts Can Help Save Fuel.

The effect weather has on fuel consumption of motor vehicles

The question of fuel efficiency often becomes an extremely acute one for drivers, especially in European countries. High prices for gasoline, environmental pollution - these factors necessitate finding ways to tightly control the amount of fuel consumed. This is of particular relevance to companies engaged in large-scale freight transportation where fuel expenses are a significant part of transport costs, and their reduction can improve the company’s market competitiveness.

Fuel expenses depend on several overall factors: the weight of the vehicle, driving habits, road conditions, and the extra energy expended in certain kinds of weather, etc.

Bearing in mind that road conditions are also often determined by different weather events, it becomes clear that, when planning prolonged resource-consuming trips, attention paid to weather forecasts is not time wasted. And for road-haulage companies, having historical meteorological data for the entire transport route can be extremely useful for assessing the appropriateness of the amount of fuel used by the driver.
