Leave No Flux Undetected Webinar Recap

Flux Webinar!


Last week, Dr. Nick (Nick Nickerson, our chief scientist) co-presented a webinar with Dr. Jesper Christiansen (University of Copenhagen) and Dr. Nabil Saad (Picarro) on all things soil flux!

Dr. Christiansen discussed his research on comparing gas flux measurements between static chambers and cavity ring-down spectroscopy (CRDS), or discrete versus continuous flux measurements, respectively. The big questions being asked were:

  1. Can we achieve better flux data with new technologies?
  2. What strategic advances do we have in terms of designing research using these new technologies?

This research by Dr. Christiansen was recently published in Agricultural and Forest Meteorology and you can find a copy of the paper “Comparison of CO2, CH4 and N2O soil-atmosphere exchange measured in static chambers with cavity ring-down spectroscopy and gas chromatography” by visiting Dr. Christiansen’s ResearchGate page.

Dr. Nick discussed the Minimum Detectable Flux (MDF) method and how it can be used to estimate the lower limit of flux rate detection with a soil flux chamber-analyzer system, or as a quality control metric for data gathered with soil flux chambers.

Dr. Saad unveiled the specifications, applications, and example data sets of Picarro Inc.’s latest CRDS gas analyzer, the Gas Scouter (G4301).

If you missed it, don’t worry! Here’s the recorded version of the webinar.
