Expected behavior

The LC CCI NetCDF product uses the _Unsigned attribute to indicate that the int8 data type should be interpreted as uint8 in the range 1 to 220 indicated by valid_minand valid_max.

Actual behavior

All unsigned LC dataset variables contain illegal negative values making the data product useless in Cate.

The reason is that xarray doesn't (yet) support the _Unsigned attribute used in the dataset, see #1579. The issue may also be solved by regenerating the LC NetCDF product, see bcdev/lc-cci-toolbox#3.

Specifications

Cate 0.9.0.dev7
