If so, please indicate where they are located: This is the only version of this dataset. METHODOLOGICAL INFORMATION 1. Description of methods used for collection/generation of data: Gravity measurements were performed with relative gravity meters in itineraries with an estimated duration of less than 8h to control and minimize the effect of the instrument drift that in each case was corrected, together with the tidal correction 2. Methods for processing the data: Calculation of observed gravity, topographic correction, open air anomaly and Bouguer anomaly using proprietary utilities and Oasis Montaj v8.5 3. Instrument- or software-specific information needed to interpret/reproduce the data, please indicate their location: The data is adquired using a Scintrex CG-6 Autograv gravimeter complemented by two GNSS receivers (Triumph 1 and Pentax G-7).Oasis Montaj v8.5 has been used for all processing steps. 4. Standards and calibration information, if appropriate: UNE-22-611-85 5. Environmental/experimental conditions: Not applicable. 6. Describe any quality-assurance procedures performed on the data:On adquired data following UNE-22-611-85 more than 7% of the statations were repeated. 7.
