As a preamble to a fully coupled integrated earth system analysis, the atmospheric model is constrained to the GMAO MERRA-2 atmospheric reanalysis (prior to June 2013) and to the GMAO operational forward processing stream (after June 2013) while the SST, SSS, ice concentration and chlorophyll data are assimilated into the coupled model using a new methodology [State Adaptive Forecast-error Estimation (SAFE): https://gmao.gsfc.nasa.gov/pubs/docs/Keppenne721.pdf] developed especially for high-resolution data assimilation.
This animation shows the ocean SSS and sea ice thickness fields (shown over grid cells where the fractional ice coverage is greater than 15%) and the vertical integral of atmospheric precipitable water (transparent overlay) sampled every 6 hours from June 1, 2012 to November 1, 2014 from a reanalysis completed with the AXIOM-1 system. The precipitations associated with tropical cyclones and other major storm systems induce localized surface freshenings which makes the corresponding storm tracks visible in the SSS field.
