Despite drastic improvements in climate model development, current simulations have difficulty capturing the interactions among different processes in the atmosphere, oceans, and ice and how they affect the Earth’s climate; this can hinder projections of temperature, rainfall, and sea level.
M²LInES will be focusing on understanding these key climate processes using two types of data:
1. [Data from high-resolution simulation and observations. ](../research4)
2. [Data resulting from model errors, also called data assimilation increments.](../research5)

## Project Goal

_We aim to reduce biases at the air-sea-ice interface in existing global climate models for reliable seasonal to multidecadal timescale projections, focusing on fundamental ocean, atmosphere, and sea-ice processes._

Two leading sources of errors contribute to climate model biases: missing processes and numerics. The missing or inadequate representation of multiscale ocean, sea-ice, and atmosphere processes (e.g., clouds, mixing, turbulence), are not resolved by the current generation of climate models due to computational limitations. Another error source arises from the climate models' numerics, which include spatial and temporal discretizations and numerical dissipation. These errors can accumulate or compensate for each other, making improving climate models intricate and requiring a range of approaches.

To tackle these biases and reduce the potential sources of error, **M²LInES’ strategy is to leverage advances in machine learning & "interrogate” the data to**

1. Develop data-informed, interpretable & generalizable subgrid physics models (ocean, ice, atm);
2. Produce error corrections derived from observational products for climate model components.

By improving model physics, this strategy ensures a more faithful representation of feedbacks and sensitivities under different climates.

### Our vision
1. _​​Generate new scientific knowledge_ in climate science from innovative use of data and machine learning: e.g., which physics did we overlook that might be important for scale interaction?
2. _Accelerate end-to-end, from development to delivery, for a new generation of climate models_; this includes learning and testing parameterizations in global frameworks to tackle significant biases in climate models.
3. _Drive a change of direction in the field by building models and tools centered around data-driven methods_ for the community to advance climate science discovery.
4. _Enable a new generation of versatile scientists working at the interface of machine learning, climate science & numerical modeling._

This [project](https://doi.org/10.48550/arXiv.2408.02161) addresses the challenge of explaining the added value of machine learning in weather and climate models, particularly for complex deep learning models. By constructing a hierarchy of Pareto-optimal models along an error-complexity plane, the researchers, including **Sara Shamekh**, provide insights into model development and performance. Through three applications—cloud cover parameterization, shortwave radiative transfer, and tropical precipitation modeling—it demonstrates how machine learning can uncover nonlinear relationships, improve parameterization, and capture key physical processes. This hierarchical approach aims to improve understanding and trust in machine learning models for atmospheric science.

General circulation models (GCMs) are essential for weather and climate prediction. They use physics-based simulations to model large-scale dynamics and small-scale processes. Recently, machine-learning models have matched or exceeded GCMs in weather forecasting accuracy, but struggled with long-term stability and ensemble forecasts. In this **[Nature paper](https://doi.org/10.1038/s41586-024-07744-y)**, co-led by **Janni Yuval**, a new model, NeuralGCM, integrates machine learning with a differentiable solver for atmospheric dynamics. It performs as well as top machine-learning and physics-based methods for short-term forecasts and can track climate metrics accurately for decades with prescribed sea surface temperature. NeuralGCM offers significant computational savings and demonstrates that deep learning can enhance traditional GCMs in predicting the Earth system. **Griffin Mooers** also contributed to the research.
