[GRASS-user] EPSG 32633 and spatial resolution for hourly LST product from Copernicus

[Nikos Alexandris]

The hourly 5km LST product from Copernicus, as per the product user manual
(https://land.copernicus.eu/global/sites/cgls.vito.be/files/products/GIOGL1_PUM_LST-I1.40.pdf)

"is displayed in a regular latitude/longitude grid (plate carrée) with
the ellipsoid WGS 1984 (Terrestrial radius=6378km). This coordinate
reference system corresponds to EPSG code 32663. The resolution of the
grid is 5/112° (approximately 0.045°)."


I imported a map (netCDF) and set the region to match it. 
If '32633' unit is 'meter', any ideas on to do with the reported:

nsres:      0.04464286
ewres:      0.04464286

which is, obviously, not meters?
Is there something "hidden" in the netCDF file(s)?

  NC_GLOBAL#comment=Land Surface Temperature (LST) is the radiative skin temperature over land. LST plays
an important role in the physics of land surface as it is involved in the processes of energy and water ex
change with the atmosphere. LST is useful for the scientific community, namely for those dealing with mete
orological and climate models. Accurate values of LST are also of special interest in a wide range of area
s related to land surface processes, including meteorology, hydrology, agrometeorology, climatology and en
vironmental studies.

  NC_GLOBAL#credit=LST products are generated by the land service of Copernicus, the Earth Observation programme of the European Commission. The LST algorithm, originally developed in the framework of the FP7/Geoland2, is generated from MTSAT/HIMAWARI and GOES data, respectively owned by JMA and NOAA, and combined with the LST product from MSG under copyright EUMETSAT, produced by LSA-SAF.
