An instrument that measures atmospheric pressure over large areas or for macroscopic weather systems, combining barometric and large-scale measurement.
From Greek 'baros' (weight/pressure), 'makro' (large), and 'metron' (measure), creating a scientific instrument name.
While baromacrometers sound incredibly specific and scientific, they represent how scientists combine root words to name instruments—each part of the word tells you exactly what it does!
