Multiwave mobile lidar and radar complex for atmospheric monitoring, wind forecasting

The complex combines modern measuring devices of X-, Ka- and infrared ranges and is designed for:

  • Providing meteorological information (horizontal and vertical wind fields, wind shear, severe weather phenomena) to dispatch and meteorological services of various facilities (airports, nuclear power plants, wind power facilities);
  • Collecting data on wind speed and direction at wind power plant sites;
  • Research in aeronautics, meteorology and ecology;
  • Control of changes in weather conditions at international competitions where weather conditions can affect safety and competition results (biathlon, ski jumping, aviation competitions).
