v77 v78 1 1 = Masked data output = 2 2 [[TracNav(doc/app/datatoc|nocollapse)]] 3 \\ 4 == General == 3 4 5 5 From release 3.7a (r483) output of masked data is implemented in PALM. This feature allows to output quantities at different mask locations, e.g. 3d volume data or 2d cross sections of arbitrary extension within the model domain; 0d or 1d data at any positions and of any amount.\\ 6 6 NetCDF4 file format is already available for masked data output.\\ 7 7 Default quantities (instantaneous and time averaged) are declared with the parameter [../d3par#data_output_masks data_output_masks], user-defined quantities can be output with [../userpar#data_output_masks_user data_output_masks_user] (see also [[../userint/output|User-defined output quantities]]).\\\\ 8 8 Since r3436, terrain-following masked output is implemented. This allows to output masked quantities at a specified height above the surface. 9 10 9 11 == Output steering == 10 12 Different [../d3par runtime parameters] steer the output of the quantities assigned with [../d3par#data_output_masks data_output_masks] and/or [../userpar#data_output_masks_user data_output_masks_user]:[=#list] … … 37 39 ...\\ 38 40 By default 50 different masks can be assigned. The amount of masks is steered with '''max_masks''' (=50 by default), which can only be changed in {{{modules.f90}}}. If more than 50 masks are desired, '''max_masks''' has to be changed to the corresponding value. 39 \\\\ 41 42 40 43 == Examples == 41 44 The following examples are given for the [../examples/cbl example_cbl run] with a model domain size of 2000m x 2000m x 2000m and a resolution of 50.0m. 42 \\\\ 45 46 * [#1.Outputofonemask 1. Output of one mask] 47 * [#2.Outputoftwodifferentmasks 2. Output of two different masks] 48 * [#3.Outputofthreedifferentmasks 3. Output of three different masks] 49 * [#4.Outputofthreedifferentmaskswithscalinglength 4. Output of three different masks with scaling length] 50 * [#5.Outputoffourdifferentmaskswithuser-definedquantities 5. Output of four different masks with user-defined quantities] 51 * [#6.Outputofterrain-followingmask 6. Output of terrain-following mask] 52 53 43 54 === 1. Output of one mask === 44 55 '''Mask 1:''' 3d volume data with an extension of 500m x 200m x 2000m from x = 0m to x = 500m, from y = 800m to y = 1000m and from the bottom to the top of the model domain. Output of instantaneous data of the three wind components.
