 ||[=#PA0704 PA0704]  || End of line or file detected for file [../iofiles#TOPOGRAPHY_DATA TOPOGRAPHY_DATA] at line ...  ||File does not contain enough data. Check the respective line given in the error message. \\ a) The number of columns (`ncols`) is less than [../initialization_parameters#nx nx]+1. \\ b) The number of rows (`nrows`) is less than [../initialization_parameters#ny ny]+1. \\ Solution: Make sure that `ncols` matches `nx+1` and that `nrows` matches `ny+1`.   ||
 ||[=#PA0705 PA0705]  || If virtual measurements are taken, the number of surrounding grid points must not be larger than the number of ghost points - 1 ||When virtual measurements are taken, data is sampled at given station grid coordinates. It is possible that also the adjoining grid points can be sampled, however, the number of grid points additionally sampled in each direction must not be larger than the number of ghost points - 1 to avoid any segmentations faults. In the future we will improve this to allow a more flexible number of offset grid points. ||
-||[=#PA0706 PA0706]  || virtual measurements require file activation string "restart" ||When virtual measurements are taken, data is output via parallel NetCDF, where the number of time-dimensions must be defined at programm start. However, when the sampling rate is high (due to small time steps, the number of sampled time steps may reach the maximum number of defined timesteps in the NetCDF file. In case this happens, PALM forces a restart run, which is the reason why the activation string must be given. ||
+||[=#PA0706 PA0706]  || dt_virtual_measurement must be > 0.0 ||This parameter is used to estimate the number of output timesteps in the output NetCDF files. With zero-valued numbers this is not possible. ||
 ||[=#PA0707 PA0707]  || Run will be terminated because virtual measurement times index exceeds its maximum value in the output files. A restart run is forced. ||Please see comment under PA0706. ||
 ||[=#PA0708 PA0708]  || If virtual measurements are taken, parallel NetCDF is required.||The PALM code need to be compiled with a parallel NetCDF library. ||
