🌍 AERIS — Cloud Detection for Landsat 8
AERIS (Automated Environmental Remote Imaging System) is a deep learning model for cloud segmentation in Landsat 8 satellite imagery with built-in uncertainty quantification using Monte Carlo Dropout.
The model performs high-accuracy binary segmentation on 4-channel satellite inputs (RGB + NIR).
🔎 Model Description
- Architecture: U-Net
- Encoder: ResNet34
- Input: 4-channel (Red, Green, Blue, Near-Infrared)
- Input Size: 256 × 256
- Output: Binary cloud segmentation mask
- Framework: PyTorch + segmentation-models-pytorch
- Uncertainty Estimation: MC Dropout (30 stochastic forward passes)
AERIS not only predicts cloud masks but also provides calibrated confidence estimates for more reliable remote sensing workflows.
📊 Performance

🚀 Usage
Installation
pip install torch torchvision
pip install segmentation-models-pytorch
Load Model
import torch
import segmentation_models_pytorch as smp
model = smp.Unet(
encoder_name="resnet34",
in_channels=4,
classes=1
)
model.load_state_dict(torch.load("Aeris_Model.pth", map_location="cpu"))
model.eval()
Inference
with torch.no_grad():
output = model(input_tensor) # input_tensor shape: [B, 4, 256, 256]
For uncertainty estimation, run multiple stochastic forward passes with dropout enabled.
📌 Intended Use
- Satellite image preprocessing
- Atmospheric correction pipelines
- Cloud cover estimation
- Weather monitoring systems
- Remote sensing research
⚠️ Limitations
- Trained only on Landsat 8 imagery
- Input size fixed at 256×256 patches
- Performance may degrade on unseen satellite domains
- Binary cloud detection (does not classify cloud types)
