case study - informative, but qualitative

regression - quantitative, but penalizes for errors in timing and bias.

spectral - quantitative, assesses power as a function of frequency regardless of timing.

We evaluate MAR and ERA-40 using several complementary analysis methods.

In general, MAR is an improvement over ERA-40in simulating surface temperature and the surface energy budget at the South Pole.
