-Since -r3707 a virtual-measurement module is available in PALM. The module enables an easy setup of virtual measurements in the model domain emulating 'real-world' observations. Virtual measurement locations are placed within the model domain according to the UTM coordinates of the 'real-world' observations. This way, not only point and profile measurements can be emulated in the model, but also complex trajectories such as spiral-shaped flight measurements or bicycle/pedestrian measurements.

With masked data output this would be hardly possible. 
+Please note, to correctly setup the virtual measurement locations the origin UTM coordinates of the lower-left edge of the model domain ([../iofiles/pids#origin_x origin_x], [../iofiles/pids#origin_y origin_y]) within the static input file should be as accurate as possible. 
 
-Documentation will be continued ...
+For different measurement sites the variables which should be sampled can be prescribed individually. Variables will be sampled at each model time step at all given coordinates. 
+The sampled data is written into binary files. PALM-4U comes with a post-processor (please see https://palm.muk.uni-hannover.de/trac/browser/palm/trunk/UTIL/combine_virtual_measurements), which merges data from the binary files and gives a single NetCDF file with all virtually sampled data for each prescribe site. 
 
--not possible with masked data output
--measurements are taken along the entire trajectory. 
--static is required, georeferencing.
