# Introduction

This is a methane emission detection dataset designed for tasks such as **methane emission classification** and **segmentation**. For each sample, the dataset includes data from three days: the **leak day (T)**, **T-90**, and **T-365**, along with the corresponding **plume mask** and **plume label** (binary).

The dataset was created by integrating data from **CarbonMapper** and **Sentinel-2**, followed by preprocessing steps such as reprojection, resizing, and cropping. Each sample is formatted as a **32x32 size** patch, as our experiments demonstrated that this size yields the best performance for the intended tasks.

For further details on the dataset and the associated experiments, please refer to our paper.


## Data Sources

This dataset is derived from the following sources:

1. **Sentinel-2**: Provided by the European Space Agency (ESA), Sentinel-2 is a high-resolution Earth observation satellite series primarily used for land monitoring, agriculture, forestry, and environmental management. For more information about Sentinel-2, visit the [ESA Sentinel-2 website](https://sentinel.esa.int/web/sentinel/missions/sentinel-2).

2. **CarbonMapper**: This initiative focuses on high-resolution hyperspectral remote sensing to monitor greenhouse gas emissions and air pollutants, supporting global efforts to address climate change. For more information, visit the [CarbonMapper website](https://carbonmapper.org).

Both sources have been preprocessed to meet the specific requirements of this dataset and standardized for ease of use.

# Overview

## Raw Collection
Raw Collection: [S2CM_RAW](https://huggingface.co./datasets/H1deaki/S2CM_RAW)
- **L2A product**: Collected **6347 samples** from **4285 plumes**.
- **L1C product**: Collected **7251 samples** from **4974 plumes**.

## Dataset Splits
The dataset is divided into three splits:
1. **L1C_temporal_split_32x32**
2. **L2A_temporal_split_32x32**
3. **L2A_location_split_32x32**

Below is a summary of the splits:

| Split Name                 | Training Samples | Testing Samples |
|----------------------------|------------------|-----------------|
| L1C_temporal_split_32x32   | 96,219           | 19,459          |
| L2A_temporal_split_32x32   | 80,660           | 20,319          |
| L2A_location_split_32x32   | 80,217           | 20,789          |
