    5555The filenames already suggest that all files have netCDF format. Informations about the file content (kind of quantities, array dimensions and grid coordinates) are part of the self describing netCDF format and can be extracted from the netCDF files using the command "ncdump -c <filename>". See [[../iofiles|netCDF data 4.5.1]] about processing the PALM netCDF data.\\\\
    5656The following quantities are available for output by default (quantity names ending with '*' are only allowed for the output of horizontal cross sections):\\\\
    57 ||='''quantity name''' =||='''meaning''' =||='''unit''' =||='''remarks''' =||
     57||='''Quantity name''' =||='''Meaning''' =||='''Unit''' =||='''Remarks''' =||
    5858||e  ||SGS || m^2^/s^2^ || ||
    5959||lwp* ||liquid water path ||m ||only horizontal cross section is allowed, requires [[../inipar#cloud_physics|cloud_physics]] = ''.T.'' ||
     
    144144Profiles can also be temporally averaged (see [#averaging_interval_pr averaging_interval_pr).\\\\
    145145The following list shows the values which can be assigned to '''data_output_pr'''. The profile data is either defined on u-v-levels (variables marked in [[span(blue,style=color: blue)]]) or on w-levels ([[span(green,style=color: green)]]). According to this, the z-coordinates of the individual profiles vary. Beyond that, with a Prandtl layer switched on ([[../inipar#prandtl_layer|prandtl_layer]]) the lowest output level is z = zu(1) instead of z = zw(0) for profiles w"u", w"v", wu and wv. Turbulence quantities such as w*u* or u*2 are calculated from turbulent fluctuations that are defined as deviations from the instantaneous horizontal average.\\\\
