non-reproducible in `2.3` buildsIf the input layers are Classic NetCDF Raster layers, the output is now as expected.cc: @ling8696
解决办法
Export both the U and V raster layers to raster datasets using the Export Data option under the Data tab and apply the Composite raster function.
Use the Composite Bands tool on the layers. From the Analysis tab > Tools > Geoprocessing pane > Toolboxes > Data Management Tools > Raster > Raster Processing > Composite Bands.
