Masked data output

General

From release 3.7a (r483) output of masked data is implemented in PALM. This feature allows to output quantities at different mask locations and can already use netCDF4 file format.
Default quantities (instantaneous and time averaged) are available and can be declared with the parameter data_output_masks, user-defined quantities can be output with data_output_masks_user.

Different runtime parameters defines the masks and steers the output:

dt_domask
mask_scale_x
mask_scale_y
mask_scale_z
mask_x
mask_y
mask_z
mask_x_loop
mask_y_loop
mask_z_loop
skip_time_domask

So far 20 different masks can be defined. Each mask is output to one local file.
Instantaneous data of mask 1 is output to file DATA_MASK_01_NETCDF, time-averaged data to file DATA_MASK_01_AV_NETCDF.
Instantaneous data of mask 2 is output to file DATA_MASK_02_NETCDF, time-averaged data to file DATA_MASK_02_AV_NETCDF.
Instantaneous data of mask 3 is output to file DATA_MASK_03_NETCDF, time-averaged data to file DATA_MASK_03_AV_NETCDF.

Besides assigned the parameters listed above, declarations have to be made in the mrun-configuration file?.
