Magnetic data grids of the Northern Vosges, surveys EOST2008 and GPR2015

Grid computation and details are explained in Gavazzi et al., 2019 [1] and exploited in Bertrand et al., [2]. This file contains non-null grid elements. PARAMETERS Format : ASCII Number of elements : 86902 Grid cell size : 125 m FIELDS - LON : grid cell WGS84 longitude (°East); - LAT : grid cell WGS84 latitude (°North ); - ALT : grid cell altitude amsl (m) - this grid was computed at a constant altitude of 1400 m above mean sea level; - TMI : total magnetic intensity anomaly (nT); - RTP : (double) reduction to the pole of the TMI (nT) - mean regional field direction Inclination=1.60°, Declination=64.14°; - DV : vertical derivative of the RTP at order 0.5 (nT/m); - DH : horizontal derivative of the RTP at order 1 (nT/m); [1] Gavazzi, B., Bertrand, L., Munschy, M., Mercier de Lépinay, J., Diraison, M. & Géraud, Y.
