Dataset specification

  • Title: ClimateBasis Nuuk - Radiation - Long wave incoming radiation @ 200 cm - 5min average (W/m2)
  • Description: Long wave incoming radiation (wavelengths of 5 to 50 µm) measured on two proximal climate stations at 200 cm above ground as a 5min average (W/m2). The double masted climate station is located between Badesø and Langsø at 40 m a.s.l.. The timeseries starts in 2008. Quality control is performed on both datasets from the double mast system. The combined time series is calculated as an average of the 2 sensors, or if data is missing from 1 sensor the other used in conjunction with a regression. Please read the metadata file provided with the data for comments related to the data in this timeseries. Radiation:Radiation ClimateBasis Nuuk:The ClimateBasis programme monitors climate and hydrology in Zackenberg, Kobbefjord and Disko (Qeqertarsuaq) and is run by Asiaq - Greenland Survey. The collected data build base-line information on climate variability and trends for all the other sub-programmes within GEM and serve as a trustworthy foundation for adaptation strategies for the Greenlandic society. The stations are embedded in Asiaq’s extensive climate and hydrology monitoring network. Furthermore, the run-off data is delivered to the World Hydrological Cycle Observing System (WHYCOS) and the Global Runoff Data Centre (GRDC) networks.

http://data.g-e-m.dk/datasets?doi=10.17897/0Y0T-XE86&column=Quality+Flag Quality Flag Text Flag assigned during quality control. Flag = "fair" is assigned instead of good to indicate where a value is interpolated, or, where only 1 timeseries has been used where it is normal to take the average of 2 timeseries. Flag = unknown is equivalent to the flag "good" or "fair" and is due a change in proceedures. Work is underway to update these flags.
