Model summary questionnaire for model ProS2St
Please note that the list below shows all questionnaires submitted for this model.
They are displayed from the most recent to the earliest, covering each 13-week competition period in which the team competed with this model.
Which of the following descriptions best represent the overarching design of your forecasting model?
- Other: Post-processing of ECMWF S2S forecasts
What techniques did you use to initialise your model? (For example: data sources and processing of initial conditions)
ECMWF S2S Forecasts
If any, what data does your model rely on for real-time forecasting purposes?
S2S forecasts
What types of datasets were used for model training? (For example: observational datasets, reanalysis data, NWP outputs or satellite data)
Reanalysis data (ERA5) and ECMWF S2S forecasts
Please provide an overview of your final ML/AI model architecture (For example: key design features, specific algorithms or frameworks used, and any pre- or post-processing steps)
A simple U-Net Architecture trained with CRPS as loss function
Have you published or presented any work related to this forecasting model? If yes, could you share references or links?
Not yet.
Before submitting your forecasts to the AI Weather Quest, did you validate your model against observational or independent datasets? If so, how?
We have built a validation pipeline that compares the past forecasts to ERA5 and the skill of the post-processed forecast compared to the raw s2s forecast.
Did you face any challenges during model development, and how did you address them?
Main challenge for us is finding time to actually work on model development.
Are there any limitations to your current model that you aim to address in future iterations?
Insufficient amount of S2S training samples - which we will address in the next period.
Are there any other AI/ML model components or innovations that you wish to highlight?
