Abstract
72300S03-I Since the start of the industrial revolution, the carbon dioxide concentration in the atmosphere has risen from about 280 parts per million to greater then 360 parts per million. As a leading greenhouse gas, the understanding of the carbon cycle is critical for predictions of global climate. Modern sensors that monitor carbon dioxide have historically been constrained to point sensors or small sample volumes that make it difficult to get the needed data for a full carbon cycle understanding. To address the need for better and more thorough carbon dioxide mapping, an eyesafe sensor, based on differential-absorption-lidar (DIAL) remote sensing techniques, will be designed and built. The sensor will provide precise range-resolved concentration measurements of carbon dioxide over large distances (greater than 1 km). Phase I will address the specific needs of the scientific community by generating a detailed lidar model for optimizing the laser system for the differential-absorption-lidar sensor. This effort will leverage other differential-absorption-lidar efforts that utilize single-frequency transmitters operating at eyesafe wavelengths. Commercial Applications and Other Benefits as described by the awardee: An eyesafe remote sensor that can accurately map the volumetric concentrations of carbon dioxide and/or other atmospheric constituents should find use in both the public and private sectors. The sensor would be utilized in climatic modeling, monitoring of global warming related species, and as an aid in the understanding of the carbon and water cycles. Additionally, these types of sensors should have application in chemical and biological agent detection and monitoring in civilian and military operations.
