Hammond's team includes Geoff Blewitt, Hans-Peter Plag and Corne Kreemer from the University of Nevada, Reno's College of Science and Zhenhong Li of the Centre for the Observation and Modeling of Earthquakes, Volcanoes and Tectonics, School of Geographical and Earth Sciences, University of Glasgow in the UK.

GPS data for Hammond and his team's research is collected through the team's MAGNET GPS Network based at the University of Nevada, Reno plus more than 1200 stations from the NSF EarthScope Plate Boundary Observatory and more than 10,000 stations from around the entire planet.

These stations include hundreds that cover Nevada, California, Oregon, and Washington. The space-based radar data comes from the European Space Agency with support from NASA.

This research was funded in the United States by the National Science Foundation and NASA and in the United Kingdom by the Natural Environment Research Council.

Their paper, "Contemporary Uplift of the Sierra Nevada, western United States, from GPS and InSAR Measurements" will be published in the peer-reviewed journal Geology in July and has just been made available online.
