Solar Eclipse Data from LI-COR

Solar Eclipse Data from LI-COR

On Monday, the LI-COR campus was in the path of totality for the August 21, 2017 solar eclipse. Here are data collected during the eclipse at our campus in Lincoln, Nebraska, USA. Even though cloud cover obscured our direct view of the eclipse, there were observable differences in light intensity, photosynthesis measurements, and environmental flux during totality.

The partial eclipse began around 11:37 AM CST, with totality happening from 1:02 PM to 1:04 PM. The eclipse was over by 2:37…

Updating Positional Tags for Biomet Data

Updating Positional Tags for Biomet Data

Version 8.0.0 of the LI-7500RS/LI-7500A/LI-7200RS/LI-7200 gas analyzer embedded software implemented a new identifier for Biomet data.  The identifier is a set of three digits that indicates the horizontal position (h), vertical position (v), and replicate number (r) at that position.  This naming protocol is based on the protocol for the AmeriFlux and ICOS networks (http://ameriflux.lbl.gov/data/aboutdata/data-variables/).  This information is stored by the LI-7550 in the biomet.metadata file for use with EddyPro® Software.  In the Sutron datalogger, there is a communications tag…

Wiring an RM Young Sonic Anemometer to a LI-COR EC System

Wiring an RM Young Sonic Anemometer to a LI-COR EC System

The RM Young 81000 sonic anemometer is one of the many sonic anemometers that can be used with a LI-COR EC system. Since the RM Young provides a junction box, wiring it to the LI-7550 is straight forward. The Analog Input/output cable (Part Number 392-10109) provided with the LI-7550 spare parts kit can be used instead of the Auxiliary Sensor Interface Unit. You can wire the bare lead ends directly to the junction box of the RM Young 81000 and…

Control Over Drought

Control Over Drought

Water is one of the most precious natural resources—and one that we often take for granted. But droughts are common and they’ve proven time and time again that we don’t know enough about the water cycle. That is why the Chinese Ecosystem Research Network (CERN) selected LI-COR eddy covariance systems to measure evapotranspiration across the country. Recently the Water and Waste Digest interviewed Dave Johnson, Senior Product Manager, to learn more about how the Chinese Ecosystem Research Network is using evapotranspiration to…

Fresh Data Every Morning

Fresh Data Every Morning

There’s nothing like a fresh download of data to get your day started. The Internet of things has made it possible for you to download your data automatically from your Eddy Covariance measurement system directly to your computer. Using wired Internet, or cellular or satellite communications, your measurement system can be remotely accessed from the comfort of your office or home. After you have set up remote access, here is a quick tip that can help you reduce…
