Time-lapse monitoring of seismic velocity at volcanic areas can provide unique insight into the property of hydrothermal and magmatic fluids and their temporal variability. Taira and Brenguier (2016) established a quasi real-time velocity monitoring system by using seismic interferometry with ambient noise to explore the temporal evolution of velocity in the Lassen Volcanic Center, Northern California.

About 40 tracking stations all over the world are currently operational for Satellite Laser Ranging (SLR), a very precise geodetic technique. Otsubo et al. (2016) ran a unique simulation to find the optimal place of a future SLR station. The answer depends on a geodetic product and one example is shown for the center of gravity of the Earth: the X and Y components are largely improved by a high-latitude station especially in the southern hemisphere, whereas the Z component is improved by a low-latitude station.

Tøffner-Clausen et al. (2016) presented the in-flight scalar calibration and characterisation of the Swarm magnetometry package consisting of the absolute scalar magnetometer, the vector magnetometer, and the spacecraft structure supporting the instruments. A significant improvement in the scalar residuals between the pairs of magnetometers is demonstrated, confirming the high performance of these instruments. Read more
Using a 46-year-long dataset of the thermospheric density during 1967–2012, Liu (2016) examined the inter-annual variability in the thermosphere at 400 km and its potential connection to El-Nino Southern Oscillation (ENSO) and stratospheric Quasi-Biennial Oscillation (QBO). Wavelet analysis reveals two major modes of the thermosphere inter-annual oscillation, with the slower mode having an average period of ~64 months and the faster mode of ~28 months. Read more
