+# Met Office UK Deterministic Dataset (Zarr Format)
+
+## Description
+This dataset is a **subset** of the [Met Office UK Deterministic Dataset](https://registry.opendata.aws/met-office-uk-deterministic/), converted from the original **NetCDF format** into **Zarr format** for modern data analysis. The Zarr files are packaged as **tar archives** for efficient storage and transfer.
+
+The subset focuses on specific variables and configurations, which are detailed in the `met_office_uk_data_config.yaml` file included in this repository. Researchers and developers can use this subset for applications in climate science, weather forecasting, and renewable energy modeling.
+
+## Usage
+This dataset is provided under the **Creative Commons Attribution 4.0 International License (CC-BY-4.0)**. When using this dataset, you must provide proper attribution to the Met Office as outlined below.
+
+## Attribution
+This dataset is derived from the [Met Office UK Deterministic Dataset](https://registry.opendata.aws/met-office-uk-deterministic/), which is British Crown copyright and provided by the Met Office under the terms of the [UK Open Government License (OGL)](https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/).

+
+## Details
+### Zarr Format and Tar Archives
+- **Format**: The dataset files are in Zarr format, a modern storage format optimized for analytics and machine learning workflows.
+- **Packaging**: Zarr files are stored as `.tar.gz` archives. Each archive corresponds to a specific time interval, such as `2022-12-01-00.tar.gz`.
+
+### Subset Configuration
+- The dataset includes a subset of variables and configurations chosen for targeted use cases.
+- For details on the variables and configurations included in this dataset, please refer to the [`met_office_uk_data_config.yaml`](./met_office_uk_data_config.yaml) file.
+
+## How to Access
+You can download and extract the tar archives using the following Python snippet:
+
+```python
+import tarfile
+
+# Example: Extracting a tar.gz archive
+archive_path = "2022-12-01-00.tar.gz"
+with tarfile.open(archive_path, "r:gz") as tar:
+    tar.extractall(path="extracted_zarr")
+```
