#seaicedataassimilation — Public Fediverse posts

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 😁? #chatgpt

Marina Durán 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.

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)

#IICWGDA11 #SeaIceDataAssimilation

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!

Davi Mignac Cameiro, from UK Met Office, presents about #SeaIce thickness #DataAssimilation in the #FOAM system. Both SMOS and CRYOSAT2 data are assimilated independently. #IICWGDA11 #SeaIceDataAssimilation

Jack Landy (CIRFA/UiT) shares some of the challenges deriving summer sea-ice freeboard and thickness from CryoSat2.

A team effort that now delivers year-round data in the #Arctic.

Robert Ricker (NORCE) explains the technique for building a Drift-Aware Sea Ice Thickness product from Satellite Altimetry. #IICWGDA11 #SeaIceDataAssimilation

We are getting ready to kick-off the 11th International Workshop on #SeaIce Modelling, Assimilation, Observations, Predictions and Verification.

We start Tuesday 21st at 9am CET in #Oslo (and online).
