| Research Abstract |
Temperature measurement in the lower troposphere with a high-spectral-resolution lidar that uses two potassium atomic absorption filters and a Ti : sapphire laser is proposed. Actual atmospheric temperature profile measurements are carried out. Between 500m and 2000m, the lidar temperature profile is good agreement with radiosonde temperature within 2K. We set up this system at Kototabang, Indonesia and we will measure the equatorial tropospheric temperature structure.
