The year 1848 marked an important turning point in the history of Switzerland: after a short civil war, the former confederation of states was transformed into the first stable republic in Europe. Just a few weeks after the conflict, a new constitution was passed, which has now formed the basis for our democratic federal state for 175 years – Switzerland was the first democracy in Europe. MeteoSwiss has been contributing to security and prosperity as Switzerland’s state weather and climate service for almost 160 years.
MeteoSwiss at the open Federal Mile
On 1 and 2 July 2023, the Federal Office of the Interior will open its doors in Bern for
anniversary celebration
the doors of various parliamentary and department buildings and many events take place. Visitors to the open federal mile have the opportunity to look behind the scenes of the federal administration and learn about the work of various departments and offices.
MeteoSwiss offers an interactive stand where you can discover
>>>>On site, our biometeorology experts will give you a detailed insight into our measuring systems and you will learn more about the importance of pollen forecasts for the prevention of allergies. You will also have the opportunity to look at pollen particles under the microscope.
Do we have smoke particles over Switzerland?
Yes, we can detect them using various measuring techniques. The most impressive is probably our Lidar (Light detection and ranging) in Payerne. We measure the total backscattered radiation of a previously emitted light beam. This allows us to determine the quantity of particles in the atmosphere at one point and assign a height to the smoke cloud. The smoke cloud has been sinking in romania phone number library the last few hours, which is related to the large-scale sinking of the air mass under the current high pressure influence. Read more about the large-scale sinking of the air under the influence of high pressure, the so-called subsidence.

The graph shows that the measurement of smoke particles increased sharply during the day on June 28th. This is because the most heavily polluted air mass, as mentioned above, sank due to subsidence. why not just buy the leads? The measuring station at the Jungfraujoch therefore found itself in the polluted air mass during the day.
We can also calculate the backward trajectories from the ECMWF global model. To do this, we calculated the arrival over Payerne in exactly this layer for four heights. These trajectories show the origin in the lower layers of agb directory eastern Canada, where the smoke cloud was located around 144 hours ago (the starting date of the trajectory calculation).
