We used these dates because this is the time period when we have the available resources to complete
the dense measurement network.
However, the consistency of the error for each year indicated by the parallel nature of the annual balance trendlines for the varying point networks suggests even greater accuracy was possible if the overall glacier balance distribution has been determined at some time using
a denser measurement network (Figure 5).
«We can pretty much tell what's happening at a global level, but if we want to understand what's happening in different regions, we really need to have
a denser measurement network and a combination of different approaches, like aircraft and tall towers,» said Dlugokencky, a co-author of the Science paper.

There is also a considerable gap in the otherwise
dense network of global ozone
measurement stations here.
(Actually, there are
measurements at some sites before 1861, but this date is generally chosen as the first time when there is a
dense enough
network of data available to make a global average meaningful).
We compared the mass balance results from a
dense network of
measurements with variously sparse
networks, to determine the error resulting from using increasingly sparse
networks.
