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…

Elizabethtown College Finds Novel Ways to Use Instruments for Classes and Research

Elizabethtown College Finds Novel Ways to Use Instruments for Classes and Research

Have you ever found yourself wishing that a fiction writer had a better grasp of scientific concepts? Dr. David Bowne at Elizabethtown College in Pennsylvania is doing his part to solve this problem—one student at a time—with a class called Ecology in Short Fiction. By providing literature students with experience with the LI-8100 Automated Soil CO2 Flux System, Dr. Bowne and his co-teacher Dr. Matt Skillen make ecological concepts meaningful to students in the context of fiction literature.

LI-820, LI-840/A, LI-8100/A, and terrible, horrible, no good, very bad data

LI-820, LI-840/A, LI-8100/A, and terrible, horrible, no good, very bad data

There are four common causes for bad readings on LI-8xxx instruments:

  1. Incorrect zero and span calibration parameters.
  2. IR light source that is failing or has failed.
  3. Contamination (dirt, corrosion, liquids) in the optical path.
  4. Failed detector.

1)  Incorrect zero and span calibration parameters:

Check these values using the LI-COR interface software for each instrument by going to:

For LI-820 and LI-840, LI-840A: View – Calibration – Advanced

For the LI-8100, LI-8100A: Utilities…

All About Timing! Determining Measurement Duration for Soil Flux Measurements

All About Timing! Determining Measurement Duration for Soil Flux Measurements

The LI-8100A SoilFluxPro™ software provides a tool to analyze the effect of observation length on measured flux values. The LI-8100A Automated Soil CO2 Flux System can be set up with varying measurement settings to account for the specific measurement conditions. A typical survey or long-term measurement consists of an observation length of 1.5 to 2.5 minutes, and a deadband of 20-30 seconds. However, these typical settings should be optimized for the specific measurement. This is especially true for measurements of…

Ten Facts About the LI-6020 Battery Charger

Ten Facts About the LI-6020 Battery Charger

The LI-6020 Battery Charger recharges 6400-03 batteries, which are designed for use with the LI-6400/LI-6400XT Portable Photosynthesis System.  These batteries can also be used with the LI-8100A Automated Soil CO2 Flux System, the LI-7000 CO2/H2O Analyzer, and the LI-610 Portable Dew Point Generator, as well as several of our discontinued instruments.  Since the batteries (and their charger) are so universal, here are ten facts you should know about the LI-6020:

  1. The LI-6020 can charge up to four 6400-03 batteries…
