[Scientific Power] Are the cleanest town in the world, are you tempted?

In the Swarba Islands, the air in a village is very clean. Wi-Fi is prohibited here, all buildings need to be unlocked to enter because they must avoid polar bears.

New Alesson is the northernmost civilian settlement site in the world

The BBC BBC reported that the surrounding air produced a diamond -like mist with each breath. This mountainside is essentially the middle of the Arctic Wilderness. The weather is very cold, but the vision is clear. The extremely dry and cold air almost immediately turned the humidity of the human mouth and nose into a tiny, shining ice crystal.

The Svalbard Archipelago, which means the cold coast, is a polar natural islands located on the Arctic Ocean and the sovereignty belongs to Norway. The Swalbart Islands are in many mountains and are along the coast. In the Arctic Circle, the climate is cold. The white and moving polar scenery and diverse polar creatures are the reason why tourists come here.

Because it is located in the Arctic Circle, there are 84 to 128 days in the winter, and the polar day from 99 to 141 days in summer. 60%of the territory of the Cold Coast Islands is covered by glaciers, and 30%of them are wasteland, and the remaining 10%have plant coverage. Mine has coal, phosphorus, iron, iron, petroleum and natural gas.

Speei Bergen is the largest island in the Swarba Islands of Norway. Many polar expeditions are based on Speutzbilgen Island as a scientific research base. The administrative center is Longyearbyn. Hotellneset landed. A airport was built here in 1975. In 1994, a total of 940 groups visited the island, including 169 tourist groups and 34 scientific inspection teams.

China dispatched a scientific examination group to the island many times around 2000-2002, and officially established the Arctic "Yellow River" scientific examination station on the island in 2004. The station is located at 78.55 degrees north latitude and 11.56 degrees east longitude. It is located in actual geography in actual geography. In terms of position, it is in the town of Olson.

New Olson is a small settlement, the permanent settlement of the northernmost tip of the world, about 765 miles (1,231 kilometers) from the Arctic.

On one side is the mountains and the other is a fjord, which is an amazing beautiful place. It may also be one of the most suitable places on the planet -far from the main pollution sources in the almost undiminished Arctic environment, the air here is the cleanest in the world.

The residents of the town are mainly scientists and come here for this reason. In 1989, a research station was established here, called Ziberlin Observatory to help researchers monitor air pollution. It has now become an important place to measure the level of greenhouse gas that leads to climate change.

But there are also signs that the air quality here may be changing. Sometimes, the atmosphere brings air from Europe and North America to the Swarba Islands, bringing pollution in these regions. Researchers not only saw that the level of certain pollutants was increasing, but also showed signs of carrying new types of pollution in the wind, which made scientists worry.

"The Ziberlin Observatory is located in a remote and primitive environment, away from the main source of pollution," said Ove Hermansen, a senior scientist at the Zepelin Observatory and the Norwegian Institute of Air. "If you can measure it here, you know that it is already popular all over the world. This is a good place to study the atmosphere of continuous changes."

The study of New Oleston is a key part of the international efforts of human impact on the atmosphere. Hermansen explained that the measurement they carried out helped "detect pollution baselines and calculate the global trend of pushing over time."

Every five days, a employee of the Norwegian Polar Research Institute boarded a cable car to the observatory, where they were maintained, collecting air samples and replacing filters on the device. Because its remote position and the height of the atmosphere can capture a small amount of pollution generated by the town's local real estate, the Ziberlin Observatory is an ideal place to help build what happened in the earth atmosphere. The sensor of the Observatory not only measures greenhouse gases, but also measures chloride gas (such as CFC), heavy metals in the air, organic phosphorus pollutants (such as pesticides), and pollution -related pollution, such as nitrogen oxides, sulfur dioxide, sulfur dioxide Granular particles such as smoke and dust.

Then, the data they collected were added to the measurement of the international station network in other places to establish the global "background" of atmospheric gas, gas solution, and particulate matter in the atmosphere to provide a benchmark for measuring pollution.

The Zeppelin Observatory can also provide early warning of changes in the atmosphere. "The monitoring of the Observatory covers a series of issues," said Hermansen, who had worked at the Qiberlin Observatory for 20 years. "Environmental toxins are particularly interesting due to their biological effects and the conditions of the Arctic, and the measurement of greenhouse gas and gas solution is particularly important on climate change worldwide."
