Each station is equipped with standard meteorological sensor as well as new technology for measuring soil moisture at spatial scales of approximately 600m diameter through cosmic-ray neutron interactions at approximately. The AMUSED network covers an area of approximately 1.7 square kilometers and will provide soil moisture estimates for hyper-resolution hydrometeorological modeling around the farm taking into account spatial scale heterogeneities not seen by satellite remote sensing products. The three sites are above chalk landscape and will improve our understanding of soil moisture and evaporation dynamics in such regions across a range of spatial scales.

The small group consisted of a post-doctoral researcher (Shams Rahman), a Civil Engineering PhD student (Joost Iwema), and a Civil Engineering undergraduate student (Juliana Koltermann da Silva) from the Universidade Federal do Rio Grande do Sul in Brazil. Shams Rahman interests include understanding groundwater-atmosphere coupling through numerical models. He is currently working under the AMUSED project. Joost Iwema is a second year PhD candidate in the Department of Civil Engineering. His background is in Soil Sciences, and he has been directly working with cosmic-ray sensors. Juliana Koltermann da Silva is a Brazilian Sciences Without Borders undergraduate student with interest in Geotechnics.
While in the field, the group had a chance to interact directly with cosmic-ray sensor developer, Darin Desilets, from Hydroinnova, asking questions and learning more about this new technology. Fieldwork activities were also supported by the Faculty of Engineering and the University of Bristol International Office.
