Scientific paper

The GAINS (Global Air-ocean IN-situ System) network of long-duration, high-altitude vehicles is proposed as a means to provide critically needed in-situ observations worldwide. This need is increasingly apparent, for example, in the Arctic where there is growing concern around the shrinking of the ice cap and sea ice extent with concomitant decreases in habitat for animal and plant species. In the mid-latitudes, the sustainability of sufficient soil moisture in grain producing regions is questionable under several climate change scenarios. Preparatory steps using smaller balloons and prototype payloads have been taken toward demonstrating the GAINS balloon concept. The balloon envelope recovery system (BERS) has been tested and radio frequency interference, compatibility and distance checks of the prototype command and communication systems were performed. Electronic and mechanical systems have been integrated in preparation for a 48-h flight of an 18-m diameter prototype.
