After a very inspiring #IICWGDA11 workshop this week on #SeaIceDataAssimilation I've downloaded some test L2 #AMSR2 #SIC observations and already got a convertor going to put it in the necessary format for assimilation.
Just gotta think about superobbing and thinning, but hopefully that'll be straightforward!

What a nice crowd !

#IICWGDA11 participants were kind enough to pose not for 1, not for 2, but for 3⃣ group pictures !

We are nice and cosy at @OsloSciencePark, thanks for the venue!

Graig Sutherland from ECCC presents about drift trajectory predictions in the Marginal Ice Zone. #IICWGDA11

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.

#IICWGDA11 #SeaIceDataAssimilation

Jozef Rusin (PhD candidate at MET Norway and UiT) presents his research on Resolution Enhanced #SeaIceConcentration from #AMSR2 at #IICWGDA11.

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!

#IICWGDA11

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)

Some fantastic talks already today at #IICWGDA11 sea ice workshop in snowy Oslo - looking forward to the next few days!❄️

Tore Wulf (DMI) presents results from the ASIP sea-ice classification, using a CNN to combine #SAR and Passive Microwave data. Very relevant in preparation for #ROSEL and #CIMR. #IICWGDA11

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.

Only 2 presentations in, and lots of food for thought at #IICWGDA11

Take home messages from @_RobertRicker. The works starts in @esaclimate, but can be expanded to today's and future missions like #CRISTAL #IICWGDA11

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).
