AI model achieves stable 10-day PM2.5 forecasts using DTW-CNN-GRU

By PulseAugur Editorial · [1 sources] ·

A research paper proposes a novel deep learning framework for long-term PM2.5 concentration forecasting, specifically designed for cities with limited monitoring networks like Isfahan, Iran. The model integrates Dynamic Time Warping (DTW) for station similarity selection with a CNN-GRU architecture, enhanced by meteorological features. This approach demonstrates stable 10-day forecasting capabilities, achieving an R2 score of 0.73 at 240 hours, outperforming existing methods without requiring computationally intensive transformer models or external tools. AI

IMPACT Enables more reliable public health early-warning systems in areas with sparse environmental monitoring data.

    Long-Term PM2.5 Forecasting Using a DTW-Enhanced CNN-GRU Model

    arXiv:2510.22863v2 Announce Type: replace-cross Abstract: Reliable long-term forecasting of PM2.5 concentrations is critical for public health early-warning systems, yet existing deep learning approaches struggle to maintain prediction stability beyond 48 hours, especially in cit…
