The data is a plain text file with comma separated columns in the order: ID, X,Y,Z, TWTT, R, where: ID: Unique identifier for each recordX,Y,Z: Geographical position of the record in UTM 22 (WGS-84) projectionTWTT: Two-way travel-time for the radarsignal to the subglacial reflection given in nano seconds.R: Relative reflectivity of the subglacial reflection in dB. The dataset was originally published in DiVA and moved to SND in 2024. Access to data through SND. Data are freely accessible. Åtkomst till data via SND. Data är fritt tillgängliga. openAccess
