The GNSS at site LL20 recorded from 2013-2017. GNSS at ZZ6A recorded from 2017 onwards and was originally located approximately five kilometres east of the final position of LL20 (see paper for diagram). GPS only data from both sites were recorded in kinematic mode for two hours per day at 30-second intervals using a dual-frequency Leica GS10. (For 2018, the ZZ6A GNSS was a Leica GX1220.) The instrument at site ZMET was located approximately 500 m west of ZZ6A and recorded from 2022 onwards for 24-hours per day at one-second intervals, using an MB100 chip. Data collection: Data collected using Leica GS10, Leica GX1200 and MB100 GPS. Data quality: The data are dual frequency raw GPS data. asNeeded completed
