ERA-Interimの解析

NCL使用

Which sea surface temperature dataset is used in the ERA-INTERIM Reanalysis model?

For ERA-interim, the prescribed lower boundary conditions are taken from different sources depending on the dates of the reanalyses:

- January 1989–June 2001: NCEP 2D-Var sea surface temperature (NCEP 2DVar)

- July 2001–December 2001: NOAA Optimum Interpolation Sea Surface Temperature v2 (NCEP OISST v2)

- January 2002–January 2009: NCEP Real-Time Global sea surface temperature

(NCEP RTG)

- From February 2009 onward: Met Office Operational Sea Surface Temperature and Sea-Ice Analysis (OSTIA) (see: http://ghrsst-pp.metoffice.com/pages/latest_analysis/docs/Stark_et_al_OSTIA_description_Oceans07.pdf)

2002年以前と以降でSSTデータの解像度が変っている。高解像度化の影響で日本の東側海上や黒潮ー親潮続流域において、大気の短周期変動成分に変化が生じている． Masunaga et al. (JC 2015)
