Right sensor, wrong multiplier?

Right sensor, wrong multiplier?

When working with your LI-COR light sensors, it’s easy to swap sensors from one instrument or channel to another. If you do this, it is important to update the calibration multipliers in order to record correct data. If you forget to update the multipliers, the data must be corrected to reflect the actual multiplier for the sensor. Fortunately, the procedure…

LI-6400 Plant Studies Video

The Organization for Tropical Studies (OTS website) filmed a short video on YouTube discussing the LI-6400 Portable Photosynthesis System and how it is being used at La Selva Biological Station in Costa Rica. The research group is focusing on Blue Fern research, including measuring photosynthesis, respiration, conductance, and light and dark reactions. See the video here.

LI-COR at AGU Conference

LI-COR at AGU Conference

LI-COR will once again be attending this year’s American Geophysical Union (AGU) Conference in San Francisco, December 13th-17th. Attendees who stop by the booth (#715) will be able to receive a hard copy of our recently published book on the eddy covariance method. For more information about the conference, go to www.agu.org . We hope to see you in California!

What’s with this humidity?

What’s with this humidity?

Relative humidity, as reported by the LI-8100A, is a calculated variable that is essentially the product of two measured variables: chamber temperature and water vapor mole fraction. Sometimes the LI-8100A will report impossible values for relative humidity, giving the appearance that something is wrong with the instrument’s infrared gas analyzer. More often than not, a bad or unbelievable relative humidity value is reported because the chamber is not connected. When the chamber is not connected, the reported chamber temperature will…
