## Reading data
### First install zarr and xarray libraries
```bash
pip install zarr xarray
```
### Lazy load the dataset
```py
import xarray as xr
ds = xr.open_zarr("zip:///::https://huggingface.co/datasets/Zeel/P1/resolve/main/all_in_one.zarr.zip")
```
Full dataset size is ~8 GB. `ds` variable contains the lazily loaded dataset, which means, it will only download a part of the data when a computation is needed on it.
For example, If we need to calculate mean of PM2.5 in Delhi for 2022, it will only download PM2.5 data of all stations in Delhi for 2022.
```py
delhi_2022_ds = ds.sel(station=ds.station.state=="Delhi", Timestamp="2022")["PM2.5"]
mean_val = delhi_2022_ds.mean().item()
print(mean_val)
# 99.5650831365871
``` |
