# Résumé des résultats à fournir

* les résultats du modèle appris sur la zone GF et testé sur la zone GF (dans la config. de test correspondant à BOOST-SWOT)
* les résultats du modèle appris sur une zone GF2 (lat : [42,52] et lon : [-45,35], patch 200*200) située le long du GF mais différente de la zone GF de test en prenant toute l’année en apprentissage et en testant sur la période «BOOST_SWOT » et la zone GF.
* les résultats d’un fine-tuning du modèle NATL (config  apprentissage boost-SWOT) sur la zone GF

Les étapes suivantes seront :

* l’évaluation de modèles de référence pour l’interpolation (la méthode que tu avais identifié + transformer)
* la mise en oeuvre sur le domaine NATL60 du 4DVarNet avec exploitation de la SST 

### July 5th week actions

* First experience: repeat the previous experiences with a lag of 30 days between training/test and training/validtation data. 
* Second Experience: boost-swot repo experience(test: (2012,10,22) ---> (2012,12,2) ), see https://github.com/ocean-data-challenges/2020a_SSH_mapping_NATL60
* Third experience: spatial training/testing split 
    * training: same as previous experiences on the north atlantic region - dim_range = {'lat': slice(30.5, 45.5),'lon': slice(-67.5, -52.5)}
    * validation: same as previous experiences on the north atlantic region - dim_range = {'lat': slice(30.5, 45.5),'lon': slice(-67.5, -52.5)}
    * test : dim_range = {'lat': slice(33, 43),'lon': slice(-65, -55)}
