Daily era5 and era5-land

[MarkMelotto]

Hi era5cli team,

Adressing issue #172: I added functionality to download era5(-land) data to era5cli.
I added some basic tests, please let me know if more are needed!

I have not yet added to the documentation, if you approve of the change I will add documentation and then we can merge!

I think some help with the checks is required 😅

We should drop Python 3.9 support as it is end of life since last year. That will solve the py3.9 job. Dropping python 3.9 can be done with:

• drop 3.9 in .github/workflows/test_and_build.yml
• in pyproject.toml set requires-python = ">=3.10" and remove "Programming Language :: Python :: 3.9" line

I was able to run

# era5 2dvar
uv run era5cli daily --variables total_precipitation --startyear 2000 --months 11
# era5-land
uv run era5cli daily --variables 2m_temperature --startyear 2000 --months 11

Do not know why this was disabled. When I run

hatch run lint | grep -v venv
./era5cli/args/periods.py:126:1: W293 blank line contains whitespace
./era5cli/args/periods.py:143:89: E501 line too long (93 > 88 characters)

./tests/test_fetch.py:565:89: E501 line too long (113 > 88 characters)

These all look like solvable problems.

It is nicer to have a single thing under test for each test.
