The horizontal visibility measured by micro pulse lidar at Hefei Airport

摘要

A measurement experiment of horizontal visibility was conducted by using a micro pulse lidar (MPL) at Hefei Airport during March of 2003. Segment-average method is used for processing the data measured by MPL. A visibility-meter and an OPC were running simultaneously at same site. The results show that the visibility measured by MPL is of a positive correlation with the ones measured simultaneously by a visibility-meter, and a negative correlation with the total number of particles measured by OPC, which indicates that it is feasible for MPL to measure the visibility.
