Real time and near real time delivery of observations is currently not a priority for GRUAN. The requirements for GRUAN are to provide upper reference observations of climate research, for the validation of globally comprehensive observations systems and for the complete characterisation of the atmospheric column. These requirements will require additional processing, which is not expected to be delivered in near real time. Stations, which already deliver observations in near real-time are encouraged to continue this delivery schedule in support of numerical weather forecasting. However, stations not connected to real time data streams are not expected to implement near real time data delivery.
