ClimateBasis Nuuk is a sub-program of the Nuuk Ecological Research Operations (NERO), which in turn is the Southwest locality of the Greenland Ecological Monitoring program (GEM).

The program monitors and studies the climate, glaciology and hydrology in Kobbefjord. The core of the program builds on several automatic weather stations, including a double-mast setup in the bottom of the fjord and several hydrometric stations monitoring the main basins in the area. In addition, snow surveys are carried out at several locations during the winter snow maximum.

The output of the monitoring program is a collection of continuous and thoroughly quality controlled time series on a range of atmospheric and hydrological parameters, all publicly available through the GEM database: http://data.g-e-m.dk/
