Evaluation of a coherent 2-µm differential absorption lidar for water vapor and radial wind velocity measurements
The performance of a coherent 2-µm differential absorption lidar (DIAL) for simultaneously measuring water vapor (H O) and radial wind velocity was evaluated. For measuring H O, a wavelength locking technique was applied to the H O-DIAL system. The H O-DIAL system was evaluated under summer daytime...

Summary: | The performance of a coherent 2-µm differential absorption lidar (DIAL) for simultaneously measuring water vapor (H
O) and radial wind velocity was evaluated. For measuring H
O, a wavelength locking technique was applied to the H
O-DIAL system. The H
O-DIAL system was evaluated under summer daytime conditions in Tokyo, Japan. H
O-DIAL measurements were compared with measurements from radiosondes. The H
O-DIAL-derived volumetric humidity values agreed with the radiosonde-derived values over the range from 11 to 20 g/m
with a correlation coefficient of 0.81 and a root-mean-square difference of 1.46 g/m
. Comparisons between the H
O-DIAL and the in-situ surface meteorological sensors demonstrated the simultaneous measurement of H
O and radial wind velocity. |
