Abstract

A method and apparatus for providing virtual weather data are described. Embodiments retrieve a plurality of weather data snapshots of historical weather data and provide an API through which a plurality of remote clients request weather data. A request specifying a first set of geographical and spatial coordinates and further specifying a first set of time and date coordinates is received. In response to the request, a first set of weather data is determined from the plurality of weather data snapshots of historical weather data, based on the first set of geographical and spatial coordinates and the first set of time and date coordinates and transmitted to the first remote client. A plurality of follow-on sets of geographical and spatial weather data are also requested and transmitted to the first remote client.
