Hello everyone,

for our project we need a source for temperature data fulfilling following criteria:

1. we need historical hourly temperature data

2. a whole year has to be covered (ideally a recent year, like, e.g. 2019) --> perfect would be a csv-file with 8760/8784 time stamps, each containing a temperature value

3. The data should be available for any geographical position worldwide (at least for any land location, where you could imagine a business or an industrial plant, since we need the data for calculations regarding these types of building)

4. The data should be for free

5. The data should be allowed for the use within a commercial application

6. In the first step, one dataset for a specific location, downloaded manually is enough. In the long run, we need to get the data for many different locations with a python-function within our project

It is quite difficult, to find a website that fulfills all these criteria. For instance, the NOAA site gets very close to our requirements. However, the data only covers the USA and it has to be requested and then gets sent per mail. We need, however, data for any continent, and we want to automate the process of getting the data from the website. This site wunderground, on the other hand, only provides hourly data for a single day, but not for a year.

Does someone know a website, that fulfills ALL the criteria, where we can get these data from?

Thanks in advance! 📷
