Fetching old tweets


Hi there,

we (students from Hamburg University Of Applied Sciences) are looking into the field of Flood Prediction based on social media data mining. In order to get some relevant data, we were asking ourselves whether or not it would be possible to access “historical” Tweets from the last big flood in Germany from end of May 2013 to June 2013.

Does anybody know how far back one may search through tweets and / or if there’s a chance to get hands on that set for this specific research question?

best regards,
Christian Hüning, Hamburg
