Paper Abstract

This letter briefly discusses the influence of I2 filter temperature on accuracy of incoherent Doppler lidar measuring wind speed. Using the 1109 line of iodine filter as edge detection, we simulated the relationship between measuring error of wind speed and I2 filter temperature. The simulation result was found that the I2 filter temperature under which the measuring error of wind speed was minimum changed with measured wind speed. We chose the I2 filter temperature as 333K and measured real wind speed with the mobile ground-based incoherent Doppler wind lidar (MIDWiL) system developed by the Ocean Remote Sensing Laboratory of the Ministry of Education of China, Ocean University of Qingdao (OUQ) in November 2000. Results showed the standard deviation of wind speed and wind direction were 0.985 m/s and 17.9 deg. respectively comparing with simultaneous data of pilot balloons.
