A dataset containing quality controlled wind observations from 183 different tall towers has been created. High resolution wind speed and wind direction measurements have been collected from existing tall towers around the world within the context of the INDECIS project in an effort to boost the utilization of these non-standard atmospheric datasets. Wind observations taken at several heights greater than 10 meters above ground level have been retrieved from various sparse datasets and compiled in a unique collection with a common format, access, documentation and quality control. For the latter, a total of 18 Quality Control checks have been considered to ensure a high quality of the wind observations. Non quality-controlled temperature, relative humidity and barometric pressure data have been also obtained and made available.
