SSM Climate Change (WQM)
RCP8.5 - YR2095

The following Python script can be used to download the Salish Sea Model climate-change hydrodynamic (HYD) and water-quality (WQM) model solutions for YR2000 and YR2095.

import urllib.request
import os

base_url = "https://s3.kopah.uw.edu/ssm-climate-rcp85"

datasets = [
    ("hyd", "2000", "ssm_{:05d}.nc"),
    ("hyd", "2095", "ssm_{:05d}.nc"),
    ("wqm", "2000", "ssm_FVCOMICM_{:05d}.nc"),
    ("wqm", "2095", "ssm_FVCOMICM_{:05d}.nc"),
]

for model_type, year, pattern in datasets:
    output_dir = os.path.join(model_type, year)
    os.makedirs(output_dir, exist_ok=True)

    for i in range(1, 2):
        filename = pattern.format(i)
        url = f"{base_url}/{model_type}/{year}/{filename}"
        output_file = os.path.join(output_dir, filename)

        if os.path.exists(output_file):
            print(f"Skipping {output_file} - already exists")
            continue

        try:
            print(f"Downloading {model_type}/{year}/{filename} ...")
            urllib.request.urlretrieve(url, output_file)
        except Exception as e:
            print(f"Failed: {url}")
            print(e)

print("Download complete.")

Output Directory

Downloaded files will be organized automatically into the following directories:

hyd/
+-- 2000/
+-- 2095/

wqm/
+-- 2000/
+-- 2095/

To download additional daily model outputs, modify the range in:

for i in range(1, 2):

For example, to download files 1 through 365:

for i in range(1, 366):
