(54) Title: BAROMETRIC INSTRUMENT AND METHOD Figure 1A (57) : The present disclosure generally relates to a barometric instrument (100) and method (200). The barometric instrument (100) comprises: a base (102); a plurality of pressure sensors (104) distributed on the base (102), each pressure sensor (104) representing a sensor position and configured for measuring a set of atmospheric pressure values at the respective sensor position; a gimbal assembly coupled to the base (102) for maintaining the pressure sensors (104) horizontally; and a processor (106) communicatively linked to the pressure sensors (104), the processor (106) configured for determining atmospheric pressure distribution on the sensor positions based on the measured sets of atmospheric pressure values, the atmospheric pressure distribution comprising a pressure gradient directed horizontally along the sensor positions.
