Apart from APECS and YESS, WCRP maintains
connections to other ECR networks, such as the Young
Hydrologic Society (YHS) and the ECR Network of Networks (NoN).
With apologies to my high - energy physics colleagues and to NASA, basic natural systems monitoring is much less expensive than high - energy colliders, fusion reactor research or manned Mars missions, but will help to provide better understanding of the lesser known parts of climate and
hydrologic systems (aerosols, clouds, large - scale climate
connections, S. Hemisphere data, etc).
