Should I Use RHI or XSECT?
You can study the three-dimensional structure of the atmosphere with the XSECT and RHI products, which show a range-height representation or vertical "slice" of a radar parameter.
If you have areas of interest, such as paths to runways at an airport, you can run RHI or XSECT products associated to those in you routine schedule.
| Feature | RHI | XSECT |
|---|---|---|
| Radar location |
Radar location is fixed to one point. |
You can make a cross section at any point along the polar volume. Note that you cannot get below the lowest elevation. |
| Resolution |
Typically, RHI gives a much better resolution. |

| Schedule |
If the user of the radar images can control the tasks, they can define a product configuration in advance (using * for the azimuth). When something interesting appears, they can run an RHI task with an azimuth determined using other IRIS products. |
You can schedule an XSECT when you want, even ad hoc. If your radars are in a network of several users, or if your task schedule is tight, you perhaps cannot let the users run RHIs when they want. |
