+

+    station_pressure : `pint.Quantity`
+        The atmospheric pressure at the designated station elevation

+        The altimeter setting value (in. Hg or hPa)
+
+    Notes
+    -----
+    This function is implemented by inverting the equations from the

+
+    The 0.3 hPa offset is subtracted from the station pressure before
