These data, rendering the vertical distribution of water contents in the subsurface, are used to show their potential in conditioning a hydrological model of the catchment, as described in the article "Magnetic resonance sounding measurements as posterior information to condition hydrological model parameters: Application to a hard-rock headwater catchment" - Journal of Hydrology (2020). Acquisition protocols follow a free induction decay scheme. Data are filtered by applying a band-pass filter at the Larmor frequency. A filter removing the 50 Hz noise is also applied with the exception of data at a Larmor frequency close to the 50 Hz harmonic. The signal envelopes are then fitted by a decaying exponential function over time to estimate the median characteristic relaxation time of each MRS sounding. specialized Hydrogeophysics Magnetic resonance sounding Headwater catchment Hard-rock aquifer Conditioning parameters of a hydrological model FRANCE 062 066 31 105708 [16 ] 2020 2352-3409 https://www.documentation.ird.fr/hor/fdi:010079736 10.1016/j.dib.2020.105708 2352-3409 [F B010079736] https://www.documentation.ird.fr/hor/fdi:010079736 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-10/010079736.pdf IRD - Base Horizon / Pleins textes 2020-11-12 2025-02-24 fdi:010079736 fre
