first satellite to measure earth's global wind pattern is set for launch - laser light measurement

A satellite designed to measure the Earth's global wind model will be launched from the Ariana space launch site in French Guiana on Tuesday.

Meteorological experts are in urgent need of reliable wind power
"Profile data to improve accuracy," ESA said in a statement . ".
Since there is almost no direct observation at all, especially the mapping of tropical winds is very poor.
Once in orbit, Fengshen can retrieve data from anywhere on Earth, including remote areas lacking ground
Based on the weather station.
The satellite will carry a large telescope measuring 1. 5 metres (five feet)

There is a sensitive receiver called Aladin and a Doppler Wind Lidar.
The Doppler lidar emits short and powerful laser pulses to the Earth in the ultraviolet spectrum.
Particles in the air-
Moisture, dust, gas-
Scatter a small part of the light energy back into the transceiver, where the light energy is collected and recorded.

The signal known as "reverse scattering" reveals the wind direction, speed, and travel distance.
Once per track, the data is downloaded to a ground station in the Svalbard Islands, Norway. The 1,260-kilo (3,000-pound)
The payload will be lifted to 320-kilometre (200-mile)

It was scheduled to rest at 21: 00 GMT on Tuesday.
Aeolus will be the fifth Earth exploration mission planned by ESA.
Other that have been completed or are in operation have measured the gravity and magnetic fields of the Earth, soil humidity, ocean salinity, and frozen expansion, collectively referred to as a low temperature circle.
The new mission will be Arianespace's 50 launches for the European Space Agency.
