Water Cycle Measurements

Because of population growth and shifting climate patterns, dependable access to fresh water is becomingly an increasingly important concern — from the Canadian wheat belt to the Middle East to sub-Saharan Africa. At the same time, excessive Monsoon and other rains can cause catastrophic flooding with a huge cost in lives and damage. Furthermore, most climate change models now recognize the important role of atmospheric moisture and clouds. These are three of the principal driving factors behind the push for scientists to better understand the complex water cycles on Earth. In addition to measuring atmospheric moisture, this requires careful tracking of water throughout these cycles, including rainwater, water in rivers, ponds and runoff, water in plants, water evaporating from plant canopies, "ancient" water trapped in ice cores, and so on.

LGR Analyzers are widely used in all these branches of water cycle research. In addition to our water analyzers, our GHG analyzers simultaneously measure carbon dioxide (CO2), methane (CH4) and water vapor (H2O) concentrations both in real-time continuous measurements as well as in laboratory analysis of captured atmospheric samples. And our Triple Isotopic Water Analyzer is extensively used to provide robust tracking on the source and age of both liquid and water vapor. In fact, this is the only instrument that simultaneously provides all three stable isotope ratios of water: δ17O, δ18O, and δ2H. In addition to providing the highest performance, another major advantage of our OA-ICOS based instruments is their rugged, compact format and their completely automated (e.g., remote) operation. This has enabled their use in water cycle research on all seven continents, in unmanned aerial vehicles, in mobile laboratories, on research and commercial aircraft, and in undersea vehicles.
