The common EOF was produced using EOF
, with the combined January
2-meter air temperature data field from National Center for
Environmental Prediction (NCEP; USA) reanalysis (Kalnay et al., (1996) "The NCEP/NCAR 40-Year Reanalysis Project", Bul. Am. Met. Soc., vol 77, no 3, 437-471; e.g. see URL: http://www.cdc.noaa.gov/index.html).
