Abstract
This dataset contains high resolution measurements of temperature, humidity and wind fluctuations from Summit Station, Greenland. These measurements and derived quantities can be used to estimate turbulent fluxes using eddy covariance. The data are collected at 10 Hz resolution and statistical properties have been calculated over both 15-minute and 30-minute flux averaging intervals (separate files).
The measurements are located at two levels on the 15 m tower:
- ace-flux-1 are the lower level (~2 m above surface) measurements, from a Metek uSonic-3 scientific 3D sonic anemometer and Licor Li-7500 gas analyzer.
- ace-flux-2 are the higher level measurements (~14 m above surface), from a Metek uSonic-3 scientific 3D sonic anemometer only (no humidity measurements).
Also see the ICECAPS-ACE: surface turbulent heat flux estimates data product for estimations of latent and sensible heat flux calculated from these components.
These data were collected as part of the joint Natural Environmental Research Council (NERC) and US National Science Foundation (NSF) -funded Integrated Characterisation of Energy, Clouds, Atmospheric state, and Precipitation at Summit - Aerosol Cloud Experiment (ICECAPS-ACE) project.
These data were continued through the 3 year extension to the ICECAPS-ACE project called ICECAPS-MELT.
