Inthis paper we present the relationship between weather andthe U.S. residents’ sentiments from Twitter data and nationwidemeteorological records. We measure how temperature,humidity, and atmospheric pressure correlate with people’smoods, demonstrating the potential of large-scale online datain humanities fields such as psychology.
