Probability of Firn Aquifer Presence in Antarctica by Combining Remote Sensing and Regional Climate Model Data
Abstract Despite in‐situ observations of perennial firn aquifers (PFAs) at specific locations of the Antarctic ice sheet, a comprehensive continent‐wide mapping of PFA distribution is currently lacking. We present an estimate of their distribution across Antarctica in the form of a probability asses...
