Working with Carbon Node data

Results from a Carbon Node are uploaded to LI-COR Cloud on the schedule (every thirty minutes by default). Widgets are used to display data from the Carbon Node. Widgets may be used to with default settings or customized to show parameters from multiple sensors and different parameters from the same station.

Overview of Dashboards

To view data from an instrument, you will create a Dashboard and add Widgets to it. LI-COR Cloud will show a variety of widgets by default. You can add, move, and re-size widgets to suit your preferences. For Carbon Nodes, two widgets may be of special interest: accumulation and gap filling.

List of widgets

Accumulation widget

Accumulations can be computed for any variable. A chart of accumulations can show data from different instruments and parameters in the group. This maybe useful for comparison of measurements from multiple sensors or sites of different parameters that help interpret the data. To set up an accumulation widget:

  1. Add a Dashboard.

    Widgets relevant to Carbon Nodes will be added automatically after you select a Carbon Node, including the Carbon Dioxide Flux Line Chart and the Accumulation widgets.

    Add a carbon accumulation widget.

  2. Customize the Widget.

    If you have saved the Widget, click Edit to view the Widget options. Then select the menu to view Chart Options. Use the Device Name and Measurement Type to constrain the list. This is to make it easier to find the parameter of interest. You can also search for measurements and constrain the date range.

    The parameter will be added to a chart when selected.

  3. Configure the display Settings, starting with Visualization Options.

    Under Bar Chart Type, you can choose Standard to display bars side-by-side or Stacked to display bars on top of each other. Under Time Frame, choose Hourly, Daily, Weekly, or Monthly to change the accumulation period.

    Accumulations presented over different periods.

  4. Apply more display properties

    You can customize the y-axis label and position, and change the display parameters of each variable. You can apply threshold indicators to change the color of a displayed parameter if it is outside some configurable bounds.

    Change display properties

  5. Save the widget to display it on the dashboard.

Gap filling widget

Gap filling is a procedure that uses existing data to fill in missing data with approximations using robust statistical methods. For fluxes from a Carbon Node, gap filled data are presented as a line chart, featuring the same display options.

To use the feature:

  1. Add a Dashboard.

    Widgets relevant to Carbon Nodes will be added automatically after you select a Carbon Node, including the Carbon Dioxide Flux Line Chart and the Accumulation widgets.

    Add a carbon accumulation widget.

  2. Configure the display settings.

    Display properties of each parameter can be changed to bring forth the most interesting aspects of the measurement.

    Congiure the gap filling options.

  3. Save the widget to display it on your dashboard.
