Hello, This question is mostly for David W Pierce, whom I have emailed directly as well.
I would like to confirm that the get.var.ncdf function within the ncdf package automatically scales output data values if there is an embedded scale factor within the ncdf file. I am reading in CRU TS 3.0 temperature and precipitation climate data, and it seems that all output data values are all correct values after applying the get.var.ncdf and then writing to raster via writeRaster (from the raster package). The metadata for the CRU data indicates a scale factor of 10, but I have not applied any conversion factor manually. I have asked the manager of the CRU data, and he suspects that many tools that read ncdf data automatically apply the scale factor. If this is the case, perhaps documenting this automatic step would be helpful for the users of netcdf data. The output data values also come out the same when reading the files into ArcMap, again, with no manual conversion factor applied.
