Revolutionizing Climate Data Storage & Access with Aeolus
Our new deep learning framework, Aeolus, dramatically reduces the size of massive weather datasets, achieving a 470x compression ratio on the 400 TB ERA5 reanalysis dataset. By employing Variational Auto-Encoder transFormer (VAEFormer) modules, Aeolus not only saves enormous storage and transmission costs but also maintains high accuracy (temperature errors as low as 0.17° Kelvin) and preserves critical climate patterns. This innovation enables faster data processing (over 1 GB/s) and makes vast meteorological datasets more accessible for research, forecasting, and climate studies, contributing to global environmental efforts.
Executive Impact
Aeolus delivers unprecedented efficiency and accuracy, transforming how climate scientists manage and leverage massive weather datasets. This capability significantly lowers operational costs, accelerates research, and improves the fidelity of climate models and predictions. Explore how this breakthrough can impact your enterprise's data strategy.

Technical Overview
Aeolus employs a dual-stage lossy-to-lossless compression scheme powered by Variational Auto-Encoder transFormer (VAEFormer) modules. The first stage, 'lossy compression', transforms high-dimensional atmospheric data into a compact latent representation, reducing storage by ~99%. The second stage, 'lossy compression', integrates a neural entropy model to further compress data by an additional 4-5x factor, delivering an exceptional overall compression ratio without compromising data fidelity. The core ACT block enhances efficiency by modeling diverse atmospheric circulation patterns with linear computational complexity, allowing for rapid encoding and decoding.
Performance Metrics
Aeolus achieves an impressive compression ratio of 470x on the ERA5 dataset, reducing its original 400 TB to just 0.85 TB. Reconstruction accuracy is maintained with a mean absolute error of 0.17 °K for temperature, 0.33 m/s for winds, and less than 0.09 hPa for mean sea-level pressure. Data processing speeds exceed 1 GB/s on an NVIDIA GeForce RTX 4090 GPU, significantly outperforming traditional methods and other deep learning approaches.
Climate Applications
The compressed CRA5 dataset preserves critical meteorological information, including climatological characteristics and spectral integrity. It effectively captures extreme events like hurricanes and heatwaves, demonstrating higher maximum wind speeds near hurricane eyes compared to raw ERA5 data. This high fidelity supports improved hurricane intensity forecasts, better disaster preparedness, and enables more accurate data-driven numerical weather prediction models, matching the performance of models trained on the original ERA5 data.

Enhanced Hurricane Intensity Forecasts with CRA5
Traditional models, including ERA5, often underestimate hurricane intensity. Our analysis of Typhoon Saola (2023) and other tropical cyclones shows that CRA5 reconstructs hurricane intensity more robustly than ERA5, with average wind speeds 0.3 m/s higher across over 3000 TC frames exceeding 20 m/s. This enhancement helps mitigate known under-estimation issues and improves warning systems for disaster preparedness, stemming from Aeolus's ability to learn effective atmospheric patterns and correct observational errors during compression.
Reliable Heatwave Monitoring with CRA5
During the May 2022 Indian heatwave, CRA5 accurately reconstructed extreme temperatures up to 45 °C, preserving both the location and magnitude of maximum values. This capability is invaluable for heatwave monitoring, enabling precise identification of vulnerable regions for public health interventions and resource allocation during heat-related emergencies. The fidelity of CRA5 ensures that critical information for public safety is maintained even under extreme compression.
