[GRASS-user] error while displaying netCDF file

Hi list,

I'm trying to import a netCDF file I downloaded from here:
http://oceandata.sci.gsfc.nasa.gov/MODISA/Mapped/8Day/4km/chl/

I've tried two different ways of importing:

r.in.gdal input=NETCDF:"A20030012003008.L3m_8D_CHL_chl_ocx_4km.nc":chl_ocx
output=test_chlor -o

and

gdal_translate -a_srs EPSG:4326 -a_ullr -180 90 180 -90 NETCDF:"
A20030012003008.L3m_8D_CHL_chl_ocx_4km.nc":chl_ocx test_chlor_b.tif
r.in.gdal input=test_chlor_b.tif output=test_chlor_b

In both cases I get this error when trying to display the map (both with
d.mon - d.rast and in the GUI):

*GRASS_INFO_ERROR(18597,1): Syntax error in cell header*
*GRASS_INFO_END(18597,1)*

though, r.info test_chlor_b, seems fine

[...]

While transforming with gdal_translate and also when unsing r.in.gdal with
the original netCDF file, I noted this:

gdal_translate -a_srs EPSG:4326 -a_ullr -180 90 180 -90 NETCDF:"
A20030012003008.L3m_8D_CHL_chl_ocx_4km.nc":chl_ocx test_chlor_b.tif
*Warning 1: dimension #1 (lon) is not a Longitude/X dimension.*
*Warning 1: dimension #0 (lat) is not a Latitude/Y dimension.*
Input file size is 8640, 4320
0...10...20...30...40...50...60...70...80...90...100 - done.

I guess it is maybe related to the error? What does it mean? Can someone
help me, please? QGIS displays it fine...

I'm using grass71 r67160, under fedora 22. GDAL 1.11.3

Thanks a lot! And sorry for my ignorance :/
Vero

ps: Here, the output of gdalinfo from original netCDF and the one converted
