Constantly follow the weather. We want to know you will be warm or cold, wet or dry. But what about the weather conditions over the long term?When we say the word air instead of the word weather? What is the boundary between the two?Adam
Scaife, head of the Meteorological Office, Hadley Centre says: "Nothing
allows us to talk about an exceptional season or exceptionally month
because of climate change. This is not possible because there is chaos in the air. "To give meaning to this mess, we can look at trends through an exceptional point of view of space.Johannes Schmidt, Chief Scientific Officer, of Mitusat says: "Satellites have a major role in giving a comprehensive picture. They provide satellite data on a very large scale. "But
when you turn up daily to the weather to the follow-up to the state of
the climate, history has a vital role because the old data is a treasure
of information.To
see the dividing line between weather and climate, and the relationship
between them, in Mitusat in Germany, monitor the weather situation is
through a fleet of European satellite, chiefly Mitusat. The organization that runs the European fleet provider with high-precision machines. This means that it runs two different satellite orbits.Stephane
Carlier, project manager for the European Space Agency (ESA) says: "The
first is the orbit geostationary orbit the Earth at an altitude of
36,000 kilometers of land approx. There is a constant monitoring on thisThe location of the land. Can be obtained on a large renovation. This means getting data in real time because the light hanging down to the ground station. But we can not see the poles.Therefore, the development of polar satellites. While moving from one pole to another, the earth continues to spin. At the end of the day, we get a full view of the Earth. "MetOp
polar satellites have greater ability to measure temperature and
humidity, and the orbiting satellites geographical hard Mitusat it
provides a dozen different picture from the ground in real time.Stephane
Carlier, he adds: "This is a picture of her twelve twelve different
wavelengths, each of which provide us with information about the Earth
and its atmosphere temperature. Is there a pull and what isAverage temperature of the earth, or atmospheric temperature, and also, one of the important aspects of Meteorology: humidity ".Thanks to satellites, we now have more information about the weather. However, these data have the ability to provide us with information we can from which to understand climate change?Johannes
Schmidt, head of team of scientists, Mitusat says: "When we get the
average weather information, any geophysical data, temperature,
humidity, over about thirtyYears, this is what we call climate reference. Satellites were not previously existed to provide climate data for the last two centuries. We do not have credible data on atmospheric temperature records before 1979.In the British Meteorological Office. Satellite data over the past thirty years is an important asset for the meteorologists for the next hours. The air they forecastersUsing Meteosat data for monitoring the atmosphere for a few months or a few years, and analyze what happened. Adam Schiff says: "Historical data has Asthaddaman Asasaaan. First through the analysis of ancient climate data, understand weather fluctuations. We can use to test the ability of computers to produce the thingItself. Whether encrypted correctly, that was based on scientific measurement and physicist correct. The
second use of the historical data used to test our expectations, so we
have to start before winter, accuracy of meteorological our knowledge in
the coming winter. We do this every year. Then look at the results of historical data.British Library. Maintains a rich history of weather data. Philip
Brohan, climate scientist, Office Hadlak Center says: "We are
interested in this to learn how to weather variation on the long-term. We
know a lot about the weather at the present time, through all the
satellite data, and other data that comes from the Meteorological
Office. But
if a big storm or something like that, people will say: "This thing
happens from time to time, the world is changing, it's kind of climate
change? "So
we have to be able to compare the weather, sensational cases of the
weather storms Awalajafav and floods, with historical records."At the British Library there are about nine thousand record for this Indian company, the oldest dating back to the year 1605.There are thousands of records in other museums as well, including the Cutty Sark records. Data recorded by the staff of the company in 1789, really helpful to know the historical situation of the weather.Historical data for resource rich weather because we know the time and place of registration. But is it accurate in the era of satellites?Johannes Schmidt says: "The satellite measurements are very different. Measure in the upper part, the atmospheric radiation fields. These radiation fields contain geophysical information is important to us. Which rates the heat and humidity, the amount of ozone in the atmosphere: wind speed on the surface of the ocean. This means that the measurement principle is quite different. Satellites measure something, and we're finding of geophysical measurements that we would like to obtain. "There
is a difference analogy, however, the link between historical data and
satellite data is that the basic rules of physics that govern the
climate system has not changed.This
means that the weather information to help scientists to correct the
climate models. They help to analyze the critical issue is when the
change in the weather works on climate change.Combining the oldest and the latest information may shed light on the controversy about the reality of climate change. There is a great need for communities to find the best ways to reduce this change.
