TL;DR: The new balloon facility in Taiki is introduced and the strategy of the Japanese scientific balloon activities is discussed, to maximize the reliability for the operation of larger balloons with heavier payloads.
Journal ArticleDOI
Re-Evaluation of Geomagnetic Field Observation Data at Syowa Station, Antarctica
TL;DR: A database of baseline values contains outliers and it is necessary to correct the continuous variation data by using absolute baseline values acquired by a magnetic theodolite and proton magnetometer at Syowa Station.
Proceedings ArticleDOI
Monitoring of GPS PWV variability at bipolar conjugate points
Wayan Suparta,Natsuo Sato,Akira Kadokura,Faizatul Noor Abu Bakar,Mardina Abdullah,Gunnlaugur Björnsson +5 more
TL;DR: A capability of GPS technique to measure the precipitable water vapour (PWV) content as a climate variable at conjugate points between Husafell station, Arctic (HUSA) and Syowa station, Antarctic (SYOG) using ground-based GPS receivers and surface meteorological measurements is presented in this paper.
