A Barograph is an instrument that can measure Atmospheric Pressure over time. They are typically included with basic meteorological observation stations. Traditionally, most barographs consisted of a pen arm that would rise and descend in accordance with relative changes in atmospheric pressure. Today, most mechanical barographs have been replaced with electronic barographs that use computer-based methods to measure pressure.
Required Parameters
At least one Air Pressure Gage, created as a Time-Series Data object, with observed data must be input to use this method. Values may be specified in units of Kilo Pascals or Inches of Mercury. The user will assign an air pressure gage to each subbasin within the Meteorologic Model editor.
