Preferred term

ULH  

Definition

  • ULH measures water vapor at high accuracy in the upper troposphere and lower stratosphere to meet the following science objectives: 1. validation and scientific collaboration with NASA earth-monitoring satellite missions, principally the Aura satellite, http://aura.gsfc.nasa.gov/ 2. observations of stratospheric trace gases in the upper troposphere and lower stratosphere from the mid-latitudes into the tropics, 3. sampling of polar stratospheric air and the break-up fragments of the air that move into the mid-latitudes, The ULH flights on Global Hawk will advance the state of the art technologically with remote command and control. ULH will provide real-time in-situ stratospheric water vapor measurements from Global Hawk. Additionally, ULH will make continuous measurements during long-duration flights up to 33 hours, which would be impossible with manned aircraft. (en)
