I am assuming that you would like to smooth in time... One very simple way
to achieve this is to plot a running mean with the ave() function. So, for a
single (lat,lon) point with t varying, instead of

ga-> d t2m

do

ga-> define tt = ave(t2m,t-3,t+3)
ga-> d tt

where [t-3,t+3] is the time window; play with the width of this window until
you find something that is reasonable. And make sure to define the smoothed
variable first because entering

ga-> d ave(t2m,t-3,t+3)

will not work (for reasons that are too technical to go into here.)
