Figure 12: Water vapor measurement using Raman lidar. Laser technology captures continuous, vertical distributions of water vapor over the Atmospheric Radiation Measurement’s Southern Great Plains Site for the 29 November - 2 December 2002 time frame. The figure represents three measurements that are important for climate studies: (a) ratio of water vapor to dry air (CART Raman Lidar Mixing Ratio Data); (b) relative humidity (CART Raman Lidar RH Data); and (c) the total atmospheric water vapor contained in a vertical column of unit crosssectional area extending from the surface to the top of the atmosphere (precipitable water vapor).
