Key Features of Tovi


Make your complex eddy covariance data understandable, accessible, and usable. View and export data in tabular and graphical format, quickly identify areas in need of gap-filling or QA/QC and discover trends visually in graphs, plots, and dashboards, including Fingerprint plots, Coverage graphs, and Energy Balance dashboards.

Coming Soon Carbon Cycle dashboard.



Get complete flux data for your carbon budget analysis with Automated Weather Station data retrieval of your driver variables for the Marginal Distribution Sampling (MDS) gap-filling technique. Developed by Reichstein et al 2005, MDS is the same technique used in FluxNet 2015 data synthesis, now available at the click of a button.

Coming Soon
Flux Gap Filling with Artificial Neural Network (ANN).

Footprint Modeling

Determine the footprint of your flux measurements around your tower using the Flux Footprint Prediction model from Kljun et al. 2015. Visualize a 2-D footprint overlaid on a satellite image of your flux site and select unique areas around your site to aggregate into your footprint results. Easily save and export your results.

New Footprint-Driven Flux Allocation Technique.


Flux Partitioning

Partition your Net Ecosystem Exchange (NEE) fluxes into Gross Primary Productivity (GPP) and Ecosystem Respiration (Reco) using the Reichstein et al. (2005) “Night-time method.” This technique models ecosystem respiration primarily as a function of temperature using only night-time data.

u* Threshold Detection

Use the new Changing Point Detection (CPD) technique (Barr, 2013) or Moving Point Test (MPT) technique for detection of friction velocity threshold.


Complete your QA/QC with a single software package. Filter your flux data by any variable or use a slider to easily set the min/max threshold.

Data Import/Export

Optimized for output from EddyPro software. Import directly into Tovi and get straight to work creating sites and beginning your analysis.

Analysis History

Revision control for your flux data analysis! Branch-like structure allows for exploratory analysis without altering earlier versions of your data.

Custom Coding Notebook

Extend the capabilities of Tovi with an embedded Python and R programming environment.

Citation Builder

Export citations for the techniques used in your Tovi analysis.

Energy Balance Collaboration Tool

Collaborate with the community to perform an evaluation of EC-derived energy flux correction tools from Mauder et al. (2013), Charuchittipan et al. (2014), and De Roo et al. (2018).
