NAVGEM 1.1 atmospheric forcing |
Expt_03.9 | 08 April 2014 | NAVGEM 1.2 atmospheric forcing |
Expt_04.0 | 02 February 2015 | NAVGEM 1.2 atmospheric forcing Includes assimilation of blended high resolution AMSR2/IMS ice concentration. Starting on 5 May 2015 erroneous SST observations over ice covered regions were inadvertently assimilated warming the underlying ocean. This caused excessive ice melting and a freshening of the surface salinity. |
Expt_04.1 | 1 May 2015 | NAVGEM 1.2 atmospheric forcing Initialized from expt_04.0 on May 1 2015 witholding the erroneous SST observations. |
Expt_04.2 | 18 April 2016 | NAVGEM 1.3 atmospheric forcing |
Expt_04.6 | 19 June 2016 | NAVGEM 1.3 atmospheric forcing Initialized from expt_04.2 on June 16 2016 to include more ice concentration observations in ACNFS |
