## Impact of super resolution SIT data for seasonal sea ice predictions | ||
### *Yiguo Wang* | ||
|
||
Accurate seasonal prediction of Sea Ice Extent (SIE) is critical for understanding Arctic climate dynamics and holds significant societal and environmental implications. | ||
The Norwegian Climate Prediction Model (NorCPM) has previously demonstrated skill in predicting pan-Arctic SIE up to 12 months ahead, primarily using ocean data and coarse-resolution Sea Ice Concentration (SIC) and Sea Ice Thickness (SIT) data. | ||
However, its capacity for regional SIE prediction remains limited to a few months, depending on season and region. | ||
|
||
This study aims to improve seasonal SIE prediction by incorporating high-resolution SIC and SIT data into NorCPM. | ||
The high-resolution sea ice data are classed to SIC data in each category. NorCPM assimilates the category SIC data. | ||
We assess the performance of this approach by conducting retrospective ensemble prediction for 2023. | ||
The experiment is initialized in March and run for up to 13 months. | ||
The prediction will be validated against observations and compared to the standard version of prediction using coarse-resolution sea ice data. | ||
