Abstract
Advanced weather and climate models use numerical techniques on grided meshes to simulate atmospheric and ocean dynamics, which are computationally expensive. Data-driven approaches are gaining popularity in weather and climate modeling, with a broad scope of applications. Although Machine Learning (ML) has been employed in this domain, significant progress has occurred in the past decade, leading to ML applications that are now competitive with traditional numerical methods. This study presents a user-friendly dataset for data-driven medium-range weather forecasting focused on India. The dataset is derived from IMDAA reanalysis datasets and optimized for ML applications. The study provides clear evaluation metrics and a few baseline scores from simple linear regression techniques and deep learning models.
