Independent performance testing of low-cost observation technologies

A variety of low-cost open source solutions are available that could significantly reduce the cost of hydro-meteorological observations, especially when manufactured or assembled directly by national services or local partners. Unfortunately, operational uptake is rather low today. This is usually not because there are problems with the technologies, but due to a lack of acceptance on the side of end-users. The WMO HydroHub views this as an opportunity and works on removing barriers to operational use of innovative solutions.
