Paper Abstract
Lidar ratio (LR) is an important parameter to invert the lidar equation to subsequently get information from the lidar
signals. Therefore, it is the objective of this study to assess the LR values for each day to implement into the inversion
method. An algorithm has been generated to estimate the lidar ratios in Penang for the Raymetrics ground-based lidar.
Daily average humidity and visibility parameters was obtained and the lidar ratios for each day in year 2014 and year
2015 were assessed. It is found that the LR values in the year 2014 and 2015 generally lie in the range from 55 sr to 85
sr. Maximum LR values in the year 2014 and 2015 is 141 sr and 177 sr respectively. Both years has the same minimum
LR value of 46 sr. Extreme values are found in both years during the haze events that occurred in Penang. The LR
values estimated are valuable as they represent the atmospheric conditions in Penang and plays an utmost important role
in the lidar inversion method.
