Revealing the buried past : geophysics for archaeologists
'Revealing The Buried Past' examines the increasingly sophisticated technology that enables archaeologists to identify much that is beneath the soil and so reduce the amount of excavation that is needed.

Geophysics : a very short introduction
Geophysics is the physics of the Earth. Encompassing areas such as seismology, plate tectonics, gravitational anomalies, and the Earth's magnetic field (present and past, as captured in rocks), it brings these together to give clues to both the structure and the workings of our planet. This Very Short Introduction describes the internal and external processes that affect the Earth, as well as the methods, using earth-and satellite-based data, used to investigate them. Throughout, William Lowrie emphasizes our need to understand the history of our planet and the processes that govern its continuing evolution.

Evaluation of SO2, SO4(2−) and an Updated SO2 Dry Deposition Parameterization in the United Kingdom Earth System Model
In this study we evaluate simulated surface SO2 and sulphate (SO4(2-)) concentrations from the United Kingdom Earth System Model (UKESM1) against observations from ground based measurement networks in the USA and Europe for the period 1987 to 2014. We find that UKESM1 captures the historical trend for decreasing concentrations of atmospheric SO2 and SO4(2-) in both Europe and the USA over the period 1987 to 2014. However, in the polluted regions of the eastern USA and Europe, UKESM1 over-predicts surface SO2 concentrations by a factor of 3, while under-predicting surface SO4(2-) concentrations by 25-35%. In the cleaner western USA, the model over-predicts both surface SO2 and SO4(2-) concentrations by a factor of 12 and 1.5 respectively. We find that UKESM1’s bias in surface SO2 and SO4(2-) concentrations is variable according to region and season. We also evaluate UKESM1 against total column SO2 from the Ozone Monitoring Instrument (OMI) using an updated data product. This comparison provides information about the model’s global performance, finding that UKESM1 over predicts total column SO2 over much of the globe, including the large source regions of India, China, the USA and Europe as well as over outflow regions. Finally, we assess the impact of a more realistic treatment of the model’s SO2 dry deposition parameterization. This change increases SO2 dry deposition to the land and ocean surfaces, thus reducing the atmospheric loading of SO2 and SO(sup 2-)(sub 4). In comparison with the ground-based and satellite observations, we find that the modified parameterization reduces the models over prediction of surface SO2 concentrations and total column SO2. Relative to the ground-based observations the simulated surface SO4(2-) concentrations are also reduced, while the simulated SO2 dry deposition fluxes increase.

Geophysics, realism, and industry : how commercial interests shaped geophysical conceptions, 1900-1960
Using wave propogation as the common thread, this is the first book to simultaneously analyze the emergence of realist attitudes towards the entities of the ionosphere and of the earth's crust. However, what led physicists and engineers to adopt realist attitudes? Anduaga Egaنna suggests that a new kind of realism--a realism of social and cultural origins--is the answer: a preliminary, entity realism responding to specific commercial and engineering interests, and a realism that was neither strictly instrumental nor exclusively operational.

Evidence for Systematic Changes in the Stratospheric Aerosol Size Following Volcanic Eruptions of Diverse Magnitudes Using Space-Based Instruments
An analysis of multiwavelength stratospheric aerosol extinction coefficient data from the Stratospheric Aerosol and Gas Experiment II and III/ISS instruments is used to demonstrate a coherent relationship between the perturbation in extinction coefficient in an eruption’s main aerosol layer and an apparent change in aerosol size distribution that spans multiple orders of magnitude in the stratospheric impact of an volcanic event. The relationship is measurement-based and does not rely on assumptions about the aerosol size distribution. In this respect, it may be a unique tool to verify the performance of interactive aerosol models used in GCMs and ESMs and may suggest an avenue for improving aerosol extinction coefficient measurements from single channel observations such the Optical Spectrograph and Infrared Imager System. We note limitations on this analysis including that the presence of significant amounts of ash in the main aerosol layer may significantly modulate these results.

Magnetic resonance imaging for groundwater
This text explains the fundamental principles and practical applications of a modern, but respected, hydrogeophysical tool: the magnetic resonance sounding method. Here, Legchenko applies the method to the characterization of aquifers and groundwater-related natural hazards.

Inverse Theory and Applications in Geophysics (2nd Edition)
The 2nd Edition of this book brings together fundamental results developed by the Russian mathematical school in regularization theory and combines them with the related research in geophysical inversion carried out in the West. It presents a detailed exposition of the methods of regularized solution of inverse problems based on the ideas of Tikhonov regularization, and shows the different forms of their applications in both linear and nonlinear methods of geophysical inversion. Its the first book of its kind to treat many kinds of inversion and imaging techniques in a unified mathematical manner.
