It looks like you are using MATLAB's websave function to download the file from the URL. However, the websave function is primarily used to download a file and save it to a specified location. It seems like you are trying to download multiple files, and it won't work as you expect because you are providing a URL of a directory, not a direct link to a specific file.
To download multiple files from the website, you will need to loop through the links in the directory and download each file individually. Additionally, you can use Python with the requests library to achieve this task more easily. Below is a Python script that demonstrates how to download multiple files from the website using the requests library: python
import requests
import os
url = 'https://oceandata.sci.gsfc.nasa.gov/MODIS-Aqua/Mapped/Daily/4km/sst/2019/'
output_directory = './downloaded_files/'
# Create the output directory if it doesn't exist
os.makedirs(output_directory, exist_ok=True)
response = requests.get(url)
if response.status_code == 200:
# Parse the HTML content to find links to files
file_links = []
lines = response.text.split('\n')
for line in lines:
if '<a href="' in line:
start_index = line.find('<a href="') + len('<a href="')
end_index = line.find('">', start_index)
file_link = line[start_index:end_index]
if file_link.endswith('.nc'): # Only consider links that point to .nc files
file_links.append(file_link)
# Download each file and save it to the output directory
for file_link in file_links:
file_url = url + file_link
out_file_path = os.path.join(output_directory, file_link)
response = requests.get(file_url)
if response.status_code == 200:
with open(out_file_path, 'wb') as f:
f.write(response.content)
print(f"Downloaded: {file_link}")
else:
print(f"Failed to download: {file_link}")
else:
print("Failed to fetch the URL.")
print("All files downloaded successfully.")
