>How can we import it to the Grass GIS as a data set?

regarding your excel data with xy-coordinates, you can use v.in.ascii, after
you saved the Excel file as a text file.

Am I right that the excel data are point information of fire events over
several years?

Please read the manuals of r.ros and co carefully, several raster data are
needed for this modules.

e.g. digital elevation models (DEM) and derived Parameters like slope and
aspect; if you don't have a DEM for your region of interest, you can use
e.g. SRTM or other public available data.

Regarding wind direction and velocity, maybe there are some meteorologic
station around your region of interest; as others already mentioned, use
this station data and e.g.interpolate these data to a raster.

Regarding humidity layers, maybe use landcover data to approximate these
parameters.

the best may be to read the module's author references, listed in the
manuals, how they compiled these needed input raster data.

It seems such information is missing in the manuals, contributions to
improve the manuals are very welcome.
