Ok, the first thing to check is if the problem is in the netcdf-c library or in ncview. Try dumping the variable in question using ncdump and the -v option. =Dennis Heimbigner Unidata p.s. If the netcdf file is not too large, then you can send it to me at dmh at ucar dot edu. On 1/16/2017 7:12 AM, Heiko Klein wrote:
Hi, I just was surprised by strange results from ncview when reading a variable with 'short' values, where all data is undefined. ncview reads all data with nc_geta_vara_float. _FillValues are defined as -32767s. Reading undefined data with nc_get_vara_float results in values = -0 or 0 for all _FillValues. I had expected a value like -32767.f (or more generally, the _FillValue translated into float) Is the 0-result really the expected behaviour of nc_get_vara_float? I have then no idea how to handling _FillValues correctly.
