Plotting a time series of Level 2 Data from Multiple Granules

[tjhearty]

The jupyter notebook on "How to Find and Plot Level 2 Data from Multiple Granules on a Map using Python" can be modified to create a new How-To document that might be titled "How to Find and Plot at time series Level 2 Data from Multiple Granules using Python".

Hey @tjhearty ,

I like the state of the notebook so far! I do have some suggestions, before I can make formatting edits:

1. For the get_CMRgranurls function, lets make it so that it only returns the HTTPS urls. This will make it a bit more readable and will avoid issues where users will try to grab the S3 URLs when not in us-west-2.
2. Let's replace the wget call with requests. I want to make it so that non-Python methods are not used when downloading granules in Jupyter Notebooks. Here's some code that can be used instead, which will work if a .netrc file is present:

datadir = 'granules'
os.makedirs(datadir, exist_ok=True)

with open('dataurls.txt', 'r') as file:
    urls = file.readlines()

for url in urls:
    url = url.strip()
    filename = os.path.join(datadir, os.path.basename(url))
    if not os.path.exists(filename):
        response = requests.get(url)
        with open(filename, 'wb') as f:
            f.write(response.content)

Great work so far! Thanks for taking this project up.

Suggestions from meeting on 9-2-24:

• Add requests, remove wget
• Make cmrgranurls() function only return one data access method (OPeNDAP or https)

We will turn the existing notebook into a use case notebook, and will have another notebook that is a more streamlined version to serve as a how-to.
