Collected date : from 2019 to 2020
Gas clathrate hydrate solid materials, ubiquitous in nature as found either on the ocean floor, permafrost on the Earth, or in extraterrestrial planets and comets, are also technologically relevant, for example, in energy storage or carbon dioxide sequestration. Nitrogen hydrate, in particular, is ...
DCF77 time of flight measurement

DCF77 is a Very Low Frequency (VLF) emitter located in Mainflingen, Germany, about 400 km away from Besançon, France. The objective of the collected data is to measure the time of flight of the 77.5 kHz signal with respect to GPS 1 PPS used as reference, and assess the dependence with ionospheric ...
