Solution to UKCA & UMUI Tutorial 8 Task 8.1

Back to the adding wet deposition tutorial

Task

You were asked to

Add in wet deposition for BOB, using the following values:

$\ k(298)\$	$\ -\left({\Delta H}/R\right)\$	$\ k(298)$ for the 1st dissociatation	$\ -\left({\Delta H}/R\right)$ for the 1st dissociatation	$\ k(298)$ for the 2nd dissociatation	$\ -\left({\Delta H}/R\right)$ for the 2nd dissociatation
$\ 0.21\times 10^{+06}\$	$\ 0.87\times 10^{+04}\$	$\ 0.2\times 10^{+02}\$	$\ 0.0\$	$\ 0.0\$	$\ 0.0\$

Solution

Changes to ukca_chem_strattrop.F90

First, you will need to increase the value of ' from 29 to 30'.

Then, you will need to change the 0 in the 7th column of the BOB' entry in the ' array to 1, e.g.

chch_t( 77,'BOB       ',  1,'TR        ','          ',  0,  1,  0)   & !  77

Finally, you will need to add the following to the end of the ' array

0.2100E+06, 0.8700E+04, 0.2000E+02, 0.0000E+00, 0.0000E+00, 0.0000E+00 &   !   30  BOB

(remembering to add a comma to the end of the preceding line).

Hand-edit

You will need to make a hand-edit containing

ed CNTLATM<<\EOF
/JPDW/
d
i
 JPDW = 30,
.
w
q
EOF

and add this to the UMUI in the Model Selectiom → Input/Output Control and Resource → User hand edit files by placing it in the table and putting a Y in the Include Y/N column.

An example hand-edit can be found at
