Abstract
There are 12 weather radars operated jointly by SMHI and the Swedish Armed Forces in Sweden.
Data from them are used for short term forecasting and analysis. The traditional way of viewing
data from the radars is in 2D images, even though 3D polar volumes are delivered from the radars
The purpose of this work is to develop an application for 3D viewing of weather radar data.
There are basically three approaches to visualization of volumetric data, such as radar data: slicing
with cross-sectional planes, surface extraction, and volume rendering. The application developed
during this project supports variations on all three approaches. Different objects, e.g. horizontal
and vertical planes, isosurfaces, or volume rendering objects, can be added to a 3D scene and
viewed simultaneously from any angle. Parameters of the objects can be set using a graphical user
interface and a few different plots can be generated.
Compared to the traditional 2D products used by meteorologists when analyzing radar data, the
3D scenes add information that makes it easier for the users to understand the given weather
situations. Demonstrations and discussions with meteorologists have rendered positive reactions.
The application will be installed and evaluated at Arlanda airport in Sweden.
