The kriging::kriging is using by default  spherical-model.

What kind of kriging function (or package) do you recommend?

My data are reanalysis data form the ECMWF (
http://data-portal.ecmwf.int/data/d/interim_daily/levtype=sfc/)  and the
aim is to interpolate them.

I would be grateful, if you could make a recommendation.

Thank you.
