Sentinel 3 and Sentinel 5P collections not available

Hi,

It has been a couple of weeks that latest data for sentinel 5P collection is not uploaded on the catalog anymore, which stops at 2025-04-10.
I have been using this python code

time_range = f"2025-04-30/2025-05-05"

catalog = pystac_client.Client.open(
    "https://planetarycomputer.microsoft.com/api/stac/v1",
    modifier=planetary_computer.sign_inplace,
)
search = catalog.search(
    collections="sentinel-5p-l2-netcdf",
    bbox=city_bounds,
    datetime=time_range,
    query={ "s5p:product_name": {"eq": "no2"}},
)
items = search.item_collection()

data = (
        stackstac.stack(
            items,
            assets=["no2"],  
            chunksize=512,
            bounds_latlon=city_bounds,
            resolution=0.1, 
            resampling=Resampling.bilinear,
            epsg=4326,
            dtype=np.float32,
        )
        .where(lambda x: x > 0, other=np.nan)
        .assign_coords(time=lambda x: x.time.dt.floor("D"), band=["no2"])
    )

which triggers

ValueError: No items

I also noticed that neither Sentinel 3 nor Sentinel 5P collections are listed anymore on Planetary Explorer ( https://planetarycomputer.microsoft.com/explore?c=30.0586%2C29.9930&z=2.00&v=2 ) .

Is there a temporary problem or the collection have been moved to somewhere else ?

Thanks

Start by querying the Planetary Computer STAC API for the sentinel-5p-l2-netcdf collection and the reported 2025-04-30/2025-05-05 range, then compare the collection list with Planetary Explorer. Check whether Sentinel 3 and Sentinel 5P were removed or renamed; done means documenting the current collection location or confirming the catalog availability problem.
