Technology Development: Nearly two decades of NASA technology investment in lidar systems and two-micron transmitters has resulted in a new capability for remotely measuring the carbon dioxide (CO2) levels in Earth’s atmosphere. NASA has developed an Integrated Path Differential Absorption (IPDA) Lidar that incorporates highenergy, double-pulse lasers with high repetition rates. The compact lidar instrument aims to provide accurate, highresolution atmospheric CO2 column measurements from an airborne platform.
A three-year NASA field expedition to examine Earth’s coral reefs is now underway, giving scientists the opportunity to study reefs ecology and condition.
NASA researchers will present new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union.
Our planet is changing on all spatial and temporal scales and studying the Earth as a complex system is essential in understanding the causes and consequences of climate change and other global environmental concerns. The purpose of NASA’s Earth Science Research and Analysis Program is to advance our scientific understanding of Earth as a system and its response to natural and human-induced changes and to improve our ability to predict climate, weather, and natural hazards.
