Common use of Sustainability gaps Clause in Contracts

Sustainability gaps. It is very expensive to maintain Arctic stations. Some of the stations are only visited every 2nd or 3rd year, and there is a risk that all data from these stations will be unavailable for a longer period of time. Such stations are often in regions with poor coverage. There is also a fear that stations in data sparse regions will be closed because they are too expensive to maintain. The sustainability problem has recently been surveyed and documented by the Copernicus In Situ Coordination Component (▇▇▇▇ et al, 2019) showing fairly good sustainability of European meteorological in situ observations, but the present analysis displays concern for the Arctic observing system.
