<p>The NY-Ålesund TurbulencE Fiber Optic eXperiment (NYTEFOX) was a field experiment at the Ny-Ålesund Arctic site (78.9<span class="inline-formula">^∘</span> N, 11.9<span class="inline-formula">^∘</span> E) and yielded a unique meteorological data set. These data describe the distribution of heat, airflows, and exchange in the Arctic boundary layer for a period of 14 d from 26 February to 10 March 2020. NYTEFOX is the first field experiment to investigate the heterogeneity of airflow and its transport of temperature, wind, and kinetic energy in the Arctic environment using the fiber-optic distributed sensing (FODS) technique for horizontal and vertical observations. FODS air temperature and wind speed were observed at a spatial resolution of <span class="inline-formula">0.127</span> m and a temporal resolution of 9 s along a <span class="inline-formula">700</span> m horizontal array at <span class="inline-formula">1</span> m above ground level (a.g.l.) and along three <span class="inline-formula">7</span> m vertical profiles. Ancillary data were collected from three sonic anemometers and an acoustic profiler (minisodar; sodar is an acronym for “sound detection and ranging”) yielding turbulent flow statistics and vertical profiles in the lowest 300 m a.g.l., respectively. The observations from this field campaign are publicly available on Zenodo (<a href="https://doi.org/10.5281/zenodo.4756836">https://doi.org/10.5281/zenodo.4756836</a>, <span class="cit" id="xref_altparen.1"><a href="#bib1.bibx18">Huss et al.</a>, <a href="#bib1.bibx18">2021</a></span>) and supplement the meteorological data set operationally collected by the Baseline Surface Radiation Network (BSRN) at Ny-Ålesund, Svalbard.</p>
