  • Here DINEOF is applied daily to METOP-B SST data from the PODAAC site. This is GHRSST Level 3C North Atlantic Regional (NAR) subskin Sea Surface Temperature produced by OSI SAF.
  • DINEOF is run on 6 months of data a first time to calculate a first EOF basis
  • Outliers are calculated and removed, following Alvera-Azcárate et al (2012) (full description here).
  • DINEOF is run a second time to calculate the final dataset.
  • Figures are prepared and posted on this webpage.
  • The whole procedure takes about 3 hours. If DINEOF is run only once, then in 1.5 hours.
