[ferret_users] integration from surface pressure level at each grid point



Dear Ferret users,


I would like to take vertical integration from surface pressure level to top level. I have estimated height with respect to pressure level; I need to take surface pressure where we have a first positive value.


For example, at one gird point (here positive values of "H" is Height above the surface)

 

yes? list/x=83/y=28  PRES,H

Z (hPa): 0 to 1013

LONGITUDE: 83

LATITUDE: 28

 Column  1: PRES is Z[GZ=H]

 Column  2: H is Height (m)

              PRES     H

10     /  1:    10.  29854.

30     /  2:    30.  22620.

50     /  3:    50.  19412.

70     /  4:    70.  17367.

100    /  5:   100.  15271.

150    /  6:   150.  12855.

175    /  7:   175.  11897.

200    /  8:   200.  11043.

225    /  9:   225.  10277.

250    / 10:   250.   9592.

300    / 11:   300.   8351.

350    / 12:   350.   7276.

400    / 13:   400.   6325.

450    / 14:   450.   5468.

500    / 15:   500.   4674.

550    / 16:   550.   3937.

600    / 17:   600.   3261.

650    / 18:   650.   2623.

700    / 19:   700.   2023.

750    / 20:   750.   1456.

775    / 21:   775.   1185.

800    / 22:   800.    922.

825    / 23:   825.    666.

850    / 24:   850.    416.

875    / 25:   875.    171.

900    / 26:   900.    -70.

925    / 27:   925.   -311.

950    / 28:   950.   -551.

975    / 29:   975.   -791.

1000   / 30:  1000.  -1031.


yes? let integrate = any_para[z=875:10@din] 

How can I define the surface pressure level at each grid pointPlease suggest. 


Best Regards

Pratik
