# Solar Wind Forecasting Dataset |
|
|
|
|
|
## Dataset Summary |
|
|
|
|
|
This dataset provides hourly solar wind plasma and interplanetary magnetic field (IMF) parameters at L1, derived from NASA’s OMNI dataset. The primary forecasting target is the solar wind speed (`V`), while additional parameters are included for completeness: |
|
|
- Solar wind speed (`V`) |
|
|
- IMF Bx (GSE) |
|
|
- IMF By (GSM) |
|
|
- IMF Bz (GSM) |
|
|
- Proton number density (`N`) |
|
|
|
|
|
The dataset is structured for machine learning experiments, particularly in this collection for evaluating foundation model efficiency for space weather forecasting tasks. Temporal coverage spans from **May 13, 2010 to December 31, 2024**, with splits designed for consistent training, validation, and testing across years. |

## Supported Tasks and Applications |
|
|
- `time-series forecasting`: Predicting future solar wind speed from past observations. |
|
|
- `regression`: Using solar wind parameters for supervised forecasting tasks. |

|
|
|
|
|
### Features |
|
|
Each row contains hourly measurements with the following fields: |
|
|
- `V`: Solar wind speed (km/s) [primary target] |
|
|
- `Bx_gse`, `By_gsm`, `Bz_gsm`: IMF components (nT) |
|
|
- `N`: Proton number density (cm⁻³) |
