IDV Time Height Plots and Probes

You can make time versus height plots of any 3D data field in HTML pages with the IDV.

Under the displays below, select a time and numerical weather prediction model for the data source. The Eta and RUC model output cover North America, and the AVN output is global.

After selecting the time and model, click on Create Plot. Ten seconds or more may be needed to retrieve the data and create the display. Data is coming from a remote Unidata data server.

Relative Humidity Time-Height Plot

The time-height pops up in a new window

The location of the vertical sample location is shown in the display in this web page by a vertical line over the center of the display. You can better see the location line by rotating the main display in 3D by dragging the mouse with the right button down over the main display.

You can move the location over the map by dragging the colored point on top of the line with the left button. A label at the top of the window shows the latitude-longitude position.

IDV Probes

The IDV probe is a sample data value at a single point in 2D or 3D fields. To make a probe of relative humidity, under the displays below, select a time and numerical weather prediction model for the data source. The Eta and RUC model output cover North America, and the AVN output is global.

After selecting the time and model, click on Create Plot. Ten seconds or more may be needed to retrieve the data and create the display. Data is coming from a remote Unidata data server.

Relative Humidity Probe

The probe output display pops up in a new window

The probe point location is shown in the display in this HTML page by a colored square point in the center of the display. You can rotate the main display in 3D by dragging the mouse with the right button down over the main display. Restore the initial overhead (map) view with ctrl-r.

You can move the location over the map by dragging the probe point with the left button. A label at the top of the window shows the latitude-longitude position.

You can add more parameters to the probe with the Commands->Add Parameters choice in the probe output display window.
