The Arctic region map. The map includes boundaries of the climate regions following the Atlas of the Arctic [Treshnikov, 1985]. The regions are identified by roman numbers I to IX. Geographical positions of 52 IGRA stations are marked with colour dots where colours (right colour bar) denote the total number of soundings in thousands. The station number is given near its location for each station. Geographical positions of the field turbulence campaigns are given by black squares. The black thin lines represent the Russian North Pole drift stations during 1979–2007.

Global sampling

Timeseries of global sampling completeness over time for GHCNMv3 (black) and the databank release (red). The globe has been split into 5 degree boxes and a single station at a timestep denotes data for that box. Boxes are defined as land if they contain any land. So to get to 100% would require sampling all small islands and all of Greenland, Antarctica, the Sahara etc. at least once each 5 degree box.
