/surface_pressure[], /air_pressure[] |
description |
repeat location independent air pressure profile (/air_pressure[]) for each grid point and replace value at the lowest level by location dependent surface pressure (/surface_pressure[]) |
|
pressure_bounds |
path |
/surface_pressure[], /air_pressure[] |
description |
repeat location independent air pressure profile (/air_pressure[]) for each grid point and replace value at the lowest level by location dependent surface pressure (/surface_pressure[]); upper and lower pressure for each profile is based on log-linear interpolation of profile (i.e. upper bound is sqrt(pressure[i+1] * pressure[i]), and lower bound is sqrt(pressure[i] * pressure[i-1])); the lower bound of level 0 is set to pressure[0] and the upper bound for level n-1 is set to pressure[n-1] |
