Headed to Greenland for fieldwork and teaching. First to Ilulissat to join a Climate Narratives team at #Illu Art and Science Hub. One goal there is to build a sea level and tides monitoring station using GNSS-IR and an array of low-cost GPS antennas. @BillMinarik and EPS #McGill alum Dave Purnell have been helping me get ready. And next week, #ACDCsummerschool has teamed up with #GRISO for a graduate school on the #GreenlandIceSheet at Disko Island research station. More soon.

@natalyagomez TIL about GNSS-IR - very interesting.

Out of curiosity: Do you store data locally and pick them up later physically, or do you send them back when measured? If the latter, what communication setup works in those remote areas?

@rhave thanks for the question. For these we will store data locally and pick up physically to process after, but David Purnell has been working on sending the data from this type of setup for other sites in Canada. We also have a paper in review on processing the raw data locally to produce ~real-time sea level time series without any comms needed. Can check out “gnssrefl” software and info by Kristine Larson for gnss-ir applications more generally.
