Christopher Jones (Univ. North Carolina) introduces Data Assimilation for Lagrangian #SeaIce Models.
New formulations are needed to include the time-varying vertices of the mesh in the Data Assimilation state vector. #IICWGDA11 #SeaIceDataAssimilation
Mitch Bushuk from #NOAA GFDL presents skills of reforcasted #Arctic September #SeaIce extent by the ensemble of Arcus Sea Ice Outlook contributions.
A lot to learn from this reforcast experiment ! #IICWGDA11 #SeaIceDataAssimilation
Today (March 23rd) is the last day of #IICWGDA11 at @Meteorologisk.
A final day full of #SeaIceDataAssimilation talks and posters.
Below are two computer-generated views of our workshop. What do you think π? #chatgpt
Marina DurΓ‘n Moro (MET Norway) carries assimilation of Level2 #SeaIce Concentration from #AMSR2 : from each orbit individually.
This performs better than assimilating daily average products, but there are regional dependency.
Sascha Willmes (Trier University) presents #Arctic #SeaIce leads "hotspots", based on their long timeseries (2002-2022) from #MODIS IR data
I think such data record should get much more attention, so much to uncover there!
Anton Korosov (NERSC) presents the new #SeaIceAge Climate Daya Record. It is based on a Lagrangian mesh and gives access to the fraction of individual age classes.
(sorry for the view angle, I am co-chairong this morning)
Phil Browne @phil_browne from ECMWF presents the updates in #SeaIceDataAssimilation in coupled ocean and sea-ice reanalysis.
So nice to finally meet Phil in person at #IICWGDA11 after many contacts online and on social media!
