Ocean Atmosphere Feedbacks in NCEP/NCAR, NCEP-DOE, ERA-40, JRA-25, CFSR, and MERRA are compared with each other and observational estimates in Kumar, A., and Z.-Z. Hu, 2012: Uncertainty in the ocean-atmosphere feedbacks associated with ENSO in the reanalysis products. Clim. Dyn., 39 (3-4), 575-588. DOI: 10.1007/s00382-011-1104-3.
Oceanic Variability in NCEP CFSR is examined in Xue, Y., B. Huang, Z.-Z. Hu, A. Kumar, C. Wen, D. Behringer, and S. Nadiga, 2011: An assessment of oceanic variability in the NCEP Climate Forecast System Reanalysis. Clim. Dyn., 37 (11-12), 2511-2539, DOI: 10.1007/s00382-010-0954-4.
