# 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. |

## 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. |
