Abstract R6]/g  
There are 12 weather radars operated jointly by smhi and the Swedish %5RY Ea  
Armed Forces in Sweden. Data from them are used for short term `GS!$9j  
forecasting and analysis. The traditional way of viewing data from the ;!&A  
radars is in 2D images, even though 3D polar volumes are delivered I\PhgFt@O  
from the radars. The purpose of this work is to develop an application rOw""mE  
for 3D viewing of weather radar data. Qn(e[ C6\  
There are basically three approaches to visualization of volumetric @Z~lM5n$8  
data, such as radar data: slicing with cross-sectional planes, surface BKfcK>%g  
extraction, and volume rendering. The application developed during |E0>-\6  
this project supports variations on all three approaches. Different n;Tpf<*U  
objects, e.g. horizontal and vertical planes, isosurfaces, or volume ren- ^kxkP}[Z.  
dering objects, can be added to a 3D scene and viewed simultaneously g}0}$WgH:  
from any angle. Parameters of the objects can be set using a graphical )YRVy  
user interface and a few different plots can be generated. :}TT1@  
Compared to the traditional 2D products used by meteorologists H1rge<  
when analyzing radar data, the 3D scenes add information that makes ]p:x,%nm  
it easier for the users to understand the given weather situations. r9'lFj
