DNMI.t2m {clim.pact} | R Documentation |
Gridded monthly mean 2-meter temperature [T(2m)], sea
level pressure (SLP), and sea surface temperature (SST) analysis for the North
Atlantic region covering the period 1873 – 1998. The actual data is
filtered though 20 EOFs (see EOF2field
), and stored as eof products in order to save
space. The lines listed in the example shows how these data have been
generated (NB. old objects with the name eof
, xxx
, climxxx
, and i
may be overwritten).
data(DNMI.t2m) data(DNMI.slp) data(DNMI.sst)
The data is a 'field' object (see retrieve.nc
).
The data is also avaialble from http://noserc.met.no.
