Abstract

National Institute of Information and Communications Technology (NICT) has made efforts in order to develop a 2-μm coherent lidar for measuring CO₂ concentration and line-of-sight (LOS) wind speed. Experimental horizontal CO₂ measurements were made to examine the detection sensitivity of the 2-μm coherent lidar in April and May, 2008, and October, 2009. Experimental vertical CO₂ measurements were made for the Greenhouse gas Observing SATellite (GOSAT) data products validation in February 2010 and in January and February 2011. Bias and random error in the LOS wind speed measurements were also investigated in order to evaluate of the 2-μm coherent lidar for wind measurements in 2010. In the paper, we present an overview of our 2-μm coherent lidar developed at the NICT and also of the experimental results.
