StratoCruiser Flight System

Page
Scientific Motivation Long duration observing platforms operating in the lower stratosphere at altitudes around 65 kft (20 km), would provide critically needed scientific breakthroughs in both the Space Sciences and the Earth Sciences. The StratoCruiser...

Climate Change & Atmospheric Chemistry

Page
While past climates have had high water vapor concentrations in the stratosphere, the Earth system has never simultaneously had high water vapor concentrations and high halogen loading as may well be the case now under high levels of climate forcing by...

Carbon Isotopic Fluxes

Page
The quantitative determination of methane and carbon dioxide isotopic fluxes from the most important source and sink regions constitutes a first order imperative in the union of energy, climate, and public policy for this country. To address this...

Methane Carbon Diox Isotopic Flux Melt Zones

Page
The massive loss of Arctic floating ice was not forecast, nor is it quantitatively understood. What is clear is that the feedbacks intrinsic to the system will eliminate the second half of the permanent ice more quickly than the first half was lost –...

Mapping the National Carbon Flux Budget

Page
One of the great challenges in the international debate over limitations on carbon release from fossil fuel combustion is the question of accurately determining the net flux of carbon based greenhouse gas emission. To answer this question in a manner that...

Mapping Methane Release from Fracking

Page
The extraction of natural gas from shale deposits by means of hydraulic fracturing, or fracking, has moved to the forefront of the strategic energy debate because of its importance to the economy and its potential impact on the environment. The key...

Photochemistry & Kinetics

Page
Photochemistry and Kinetics: A Critical Component of Global Change Research On the global scale, with little doubt, the most successful intersection of fundamental science and public policy is the case linking ground-level CFC release with the catalytic...

Long Duration Stratospheric Systems

Page
Technical Summary of the Flight System StratoCruiser Propulsion Module offers unprecedented mobility and measurement capability combining the persistence of balloon platforms for greatly extended observing times, station keeping over the central U.S. in...

High-Altitude Aircraft & Satellites

Page
To understand the chemistry of our atmosphere, we need to be able to measure which chemical species are present in what concentrations and how those concentrations vary in space and time. For some purposes, very broad measurments can be made from...

Flight Electronics

Page
The electronics group provides electrical engineering support to flight and lab experiments. This includes determining system requirements, specifying system architectures, designing of custom electronics as necessary, building and testing complete...

Lasers & Optics

Page
We use light as part of the detection system in almost every instrument we build. Light of appropriate frequencies can be used to excite molecules, causing them to fluoresce, or the light may be absorbed, with the depth of the absorption indicating the...
