So, basically, here I'm attemping to create a Python script that will perform next tasks:

Read RAINBOW volume dBZ radar data (path to the data file: dBZ.vol)
Reproject the radar data file from original raw polar coordinates that are in the file to cartesian coordinates, and later to EPSG:2180 coordinate system
Clip the radar data to the extent of Masovian region
Visualize and plot the processed radar data in a simple way
Though currently, unfortunately, I'm encountering with several issues in the Python code. Your task - is to fix all of them and provide a complete updated code. The issues are:
Color bar on the plot is being duplicated
The extent of radar data on the plot is way smaller than it should be (the original raw extent of the radar scanning is perfectly 125km from the radar site, a circle-like extent common for the weather radars + of course this should be accounted to the data cutting for specific masovian region extent), here's a basic function that might help with getting the masovian region extent:
def get_masovian_boundary():
url = "https://raw.githubusercontent.com/ppatrzyk/polska-geojson/master/wojewodztwa/wojewodztwa-medium.geojson"
Fetch the content using requests
response = requests.get(url)
if response.status_code == 200:
data = response.json()
# Set the CRS to EPSG:4326 when creating the GeoDataFrame
gdf = gpd.GeoDataFrame.from_features(data["features"], crs="EPSG:4326")
masovian = gdf[gdf['nazwa'] == 'mazowieckie']
return masovian
else:
print(f"Error fetching GeoJSON data: {response.status_code}")
return None
But of course in our code we already have a data file - the masovian_boundary.geojson. But it's structure is literally the same 1:1.
3. The radar data plotted on the plot differs from my expectations. It looks like a small circle filled with dark blue color and random, grainy data not representing actual radar data storaged in the dBZ.vol that we need to decode and visualize

Here's also a console log returning when running the code that might significantly help you:
