LI-200R Pyranometer Performs Well in NREL Solar Radiation Assessment Tests

LI-200R Pyranometer Performs Well in NREL Solar Radiation Assessment Tests

Prior to the official product launch, LI-COR provided the National Renewable Energy Laboratory (NREL) with a set of LI-200R Pyranometers for their long-term solar radiation measurement project. The LI-200R is based on the proven LI-200 Pyranometer, but with a more robust cable and an improved seal against water vapor. The sensor is also detachable from the base/cable, simplifying installation and removal. Click here for a detailed comparison between the old and new sensor designs. 

NREL is a US government…

Potsdam GHG Flux Workshop – From Natural to Urban Systems, 19-23 October 2015, Potsdam, Germany

Potsdam GHG Flux Workshop – From Natural to Urban Systems, 19-23 October 2015, Potsdam, Germany

GHG BannerThe one-week workshop united experts on greenhouse (GHG) gas flux measurements, data processing, and data uncertainty with flux processing applications in natural and urban environments.

The workshop included keynote lectures from some of the most outstanding scholars in the field, combined with demonstrations and hands-on sessions on soil flux, eddy covariance, and data processing. Topics ranged from equipment setup, data handling, flux processing, gap filling, partitioning, and footprint analysis, to applications in…

Look Ma, No Wires! Wireless connectivity and the LI-6400XT

The LI-6400XT Portable Photosynthesis System is a versatile instrument with a wide variety of features.  These features include several fun leaf chambers, light sources, outstanding IRGAs, wired network connectivity, and a generally pleasant personality to help you acquire your scientific data.  However, there are occasionally features that we’re asked for that we haven’t yet been able to include.  One such feature is wireless network connectivity.  Although not included with a LI-6400XT, it is possible to easily add this feature yourself. …

Software for Fitting Photosynthetic CO2 or Light Response Curves

Software for Fitting Photosynthetic CO2 or Light Response Curves

A frequent question from LI-COR LI-6400XT users is a request for software resources for fitting the Farquhar, von Caemmerer and Berry (FvCB) model of photosynthesis (Farquhar, von Caemmerer & Berry 1980).  There is a wealth of literature on this topic and a variety of methods developed to fit the model.  However, there are currently no commercial software packages available for this purpose. Several software resources are freely available for fitting the FvCB model of photosynthesis in a variety of software…
