Unique data sources

Every weather model requires weather observations to initialize the forecast, and GRAF uses the same system as the GFS to get the initial weather conditions. However, GRAF has the capability to crowdsource additional weather data by using pressure sensor readings sent from barometers found within smartphones, if people opt in to share that information. In addition, hundreds of thousands of pesonal weather stations, many operated by amateur weather enthusiasts, will also be able to contribute data to the model. These additional data sources will require some challenging quality assurance algorithms, and it will be very interesting to see by how much this crowd-sourced data improves forecasts.
