NCEP NARR
A high resolution (32km x 29 pressure levels) data set focused upon the North American Region. Relative to the NCEP-DOE (R2) it has a much improved land-hydrology, diurnal cycle and land-atmosphere interaction. As such, it can be considered a second generation reanalysis. A unique feature is the direct assimilation of observed precipitation.
