We know what is the weather in the online users current location, right now. We also know how they perceive that weather and how it influences their everyday decisions. Finally we use that information to marketers, advertisers and business decision makers for their better marketing budget spending, campaign targeting and improving operations. I have designed and created a system that a) collects and stores in Cassandra wide range of weather related data from: weather providers, meteorological institutes, historical climate data and aviation weather services; b) computes weather segments by crunching collected data and c) tags online users with weather segments based on IP geolocation.
