As a part of my study process, I am working on my final project which relies on Wunderground API and is an essential data source. Project must be finalized till June 2019 and I was wondering if there was a chance to receive an API key for this purpose.
I'm sorry, ME, you've picked a bad time to base your project on this resource. My best recommendation, as someone with a PhD myself, would be for you to find another platform you can use. If you have money in your budget for data, I could help you explore The Weather Company's data, but if, like many researchers, you're working on a shoestring, you would be better off exploring other options.
