Loon Stratospheric Sensor Data

<p>This data set contains flight data from Loon, a Google project and later an Alphabet subsidiary that provided wireless internet access to rural areas using high-altitude balloons. The data set includes GPS and sensor data from all 2,131 flights across the project&#39;s entire nine-and-a-half year history, from the first sounding balloon experiment in August, 2011, through the last balloon landing in May, 2021. In total the data set comprises over 218 flight-years of data (over 127 million telemetry points), the vast majority from altitudes between 50 and 110 hPa (approximately 15.5 to 21 km above sea level).</p> <p>Please see README.md within the dataset&nbsp;for more details.</p>
