+ # Model Introduction
18
+
19
+ WRF-ML bridges WRF v4.3 and Python machine-learning parameterizations. This reproduction focuses on the recommended Model D, using a bidirectional LSTM to emulate RRTMG shortwave and longwave outputs.

+ # Model Description
25
+
26
+ The model was proposed by researchers at Alibaba Group's Damo Academy. It was trained with atmospheric-column inputs and RRTMG outputs generated by WRF simulations, with 57 vertical levels per sample. Through layout adaptation and a synchronous request-response protocol, it supports shortwave and longwave flux and heating-rate emulation as an online WRF physical parameterization.

+ | :---: | :--- |
32
+ | Radiation emulation | Emulate shortwave and longwave fluxes and heating rates. |
33
+ | WRF parameterization | Validate atmospheric-column batching and output layout restoration. |
34

+ ## Download
42

45
+ cd WRF-ML
46

+ ### Environment Dependencies
49
+
50
+ **Hardware Requirements**
51
+
52
+ - A GPU or DCU is recommended.
53
+ - A CPU can run the default small-sample connectivity configuration.
54
+ - DCU users should install DTK 25.04.2 or a compatible OneScience-recommended version first.
55
+
56
+ **DCU Environment**
57
+
58
+ ```bash
59
+ # Activate DTK and Conda first
60
+ conda create -n onescience311 python=3.11 -y
61
+ conda activate onescience311
62
+ pip install onescience[earth-dcu] -i http://mirrors.onescience.ai:3141/pypi/simple/ --trusted-host mirrors.onescience.ai
63
+ ```
64
+
65
+ **GPU Environment**
66
+
67
+ ```bash
68
+ # Activate Conda first
69
+ conda create -n onescience311 python=3.11 -y libstdcxx-ng=12 libgcc-ng=12 gcc_linux-64=12 gxx_linux-64=12
70
+ conda activate onescience311
71
+ pip install onescience[earth-gpu] -i http://mirrors.onescience.ai:3141/pypi/simple/ --trusted-host mirrors.onescience.ai
72
+ ```
73
+
74
+ ## Synthetic Data
75
+
76
+ The paper uses a `190x170` horizontal domain, 57 vertical levels, and WRF-RRTMG columns sampled every 30 minutes. Synthetic data preserve 57 levels, WRF layout conversion, and six output semantics while reducing column count, hidden width, and epochs; the ten inputs are explicitly an engineering ledger because the paper does not enumerate all input variables. Results verify the workflow only and do not represent paper performance.
77
+
78
+ ```bash
79
+ python scripts/fake_data.py
80
+ ```
81
+
82
+ ## Training
83
+
84
+ ```bash
85
+ python scripts/train.py
86
+ torchrun --nproc_per_node=2 --nnodes=1 --master_addr="localhost" --master_port=29500 scripts/train.py
87
+ ```
88
+
89
+ The default synthetic run jointly optimizes 57-level radiation profiles and boundary fluxes, and both single-process and two-process DDP training have been verified. It produces one recoverable Model-D-style checkpoint and records normalized mean squared error. Training results are saved to:
90
+
91
+ ```text
92
+ result/checkpoints/wrf_ml.pt
93
+ result/training/metrics.json
94
+ ```
95
+
96
+ ## Weights
97
+
98
+ The paper's code and data are archived at https://doi.org/10.5281/zenodo.7407487. This reproduction does not link a pretrained checkpoint because a separately licensed official weight artifact was not confirmed.
99
+
100
+ ## Inference
101
+
102
+ ```bash
103
+ python scripts/inference.py
104
+ ```
105
+
106
+ Inference restores the checkpoint, runs the synchronous layout-adapted coupler, and produces 57-level profiles and boundary fluxes. Profile and boundary output shapes are `[6,57,4]` and `[6,2]`, respectively, and both have passed finite-value checks. Inference results are saved to:
107
+
108
+ ```text
109
+ result/output/predictions.npz
110
+ ```
111
+
112
+ ## Evaluation
113
+
114
+ ```bash
115
+ python scripts/result.py
116
+ ```
117
+
118
+ Evaluation reports RMSE for shortwave and longwave fluxes, heating rates, and boundary shortwave fluxes and creates a vertical-profile comparison. All metrics are finite, and the PNG has passed format and non-empty-pixel checks. Evaluation results are saved to:
119
+
120
+ ```text
121
+ result/evaluation/metrics.json
122
+ result/evaluation/comparison.png
123
+ ```
