Directory Contains Magnetic and Radiometric data from the Kviteseid-Notodden-Ulefoss area, Telemark county. NGU Report 2013.049 describes acquisition, quality, processing and presentation of the data. Magnetic data are presented as: Total magnetic field (Notodden_miclev_mag_sorted) Magnetic Horizontal Gradient (Notodden_sorted_HG_miclev_mag) Magnetic Vertical Gradient (Notodden_sorted_VG_miclev_mag) Magnetic Tilt Derivative (Notodden_sorted_TD_miclev_mag) A low pass filter was applied to smooth the resulted magnetic grids (See in folder LP300) Geosoft XYZ-file with magnetic anomaly, IGRF value, instrument height and altitude above sea level. Notodden_Magnetics.XYZ Radiometric data are presented as: Radiometric Ternary Map (Notodden_Mergred_Ternary_Normal_dist) Radiometric Total Count (Notodden_Mergred_miclev_TC_C) Potassium ground concentration in % (Notodden_Mergred_miclev_K_C) Uranium ground concentaration in ppm (Notodden_Mergred_miclev_U_C) Thorium ground concentration in ppm (Notodden_Mergred_miclev_Th_C) A 3x3 convolution filter was applied to smooth the concentration grids (See in folder 3x3_conv) Geosoft XYZ-file of Unanium, Thorium and potassium ground concentrations.
