The open path LI-7500RS is ideal for power-limited deployments.
On the northern coast of Alaska, USA, conditions are challenging for any instrument system. Here, the LI-7500A measures CO2 and water vapor flux in combination with CH4 flux measurements from an LI-7700 Open Path CH4 Analyzer.
The LI-7500 and LI-7500A are the most trusted open path CO2/H2O analyzers in the world. Since 1999, the analyzers have been cited in over 3500 scientific publications. That’s one new citation per day for more than 10 years.
Great Barrier Reef, Australia
Afloat over the southern Great Barrier Reef, this station measures energy and carbon exchange for researchers at the School of Geography, Planning, and Environmental Management, the University of Queensland, Australia.
Deployed over seven continents. Deployed over five oceans, too.
Selected by more than
networks worldwide—from CarboEurope to the Chinese Ecological Research Network.
The LI-7500—predecessor to the LI-7500RS—was used by many scientists from the Intergovernmental Panel on Climate Change, which was awarded a Nobel Prize in 2007.
Quinghai-Tibetan Plateau, China
Measurements of CO2 and water vapor flux over an alpine wetland on the Quinghai-Tibetan Plateau in China. This site includes CH4 flux measured with an LI-7700 Open Path CH4 Analyzer.
