NCEP Reanalysis (R2)
NCEP-DOE Reanalysis II (R2) is an improved version of the NCEP-NCAR Reanalysis I (R1). The improvements include an updated model with better physical parameterizations, assorted data assimilation errors were fixed and additional data were included. Still, it is still a 'first generation' product.
Improved version of NCEP-NCAR (R1)
Still a 1st generation reanalysis
Low spatial and temporal moisture variability over oceans (mainly model 'first guess' fields)
poor Southern Hemisphere
