several orders larger in depositions when ocean surface transport is enabled

Dear HYSPLIT,

I did simulations using GFS data to compare depositions with ocean surface transport being switched on and off (see the attached, left is off, right is on). The 2- to 3-order differences seemed quite significant. Could you provide some insight into this?

vmsread.f formatted printing of mass percentage

The F6.2 specifier to print the percentage may lead to the merging of two columns when it's 100%, changing to F7.2 around line 106 in vmsread.f can fix the problem.

Re: Using hourly GFS in HYSPLIT

I'm using api2arl_v6 and it doesn't seem to have a problem:
$ rm *.cfg
$ api2arl_v6 -z1 -igfs.t12z.pgrb2.0p25.f001 -of001.arl
$ rm *.cfg
$ api2arl_v6 -z1 -igfs.t12z.pgrb2.0p25.f006 -of006.arl

chk_file output for f001.arl:

how to make con2rem calculate dose from pollutant's decay products as well?

Is there a way to accurately calculate the dose from both the pollutant and its decayed products? Say I run hysplit for Cs-137, but when calculating the dose, I'd like to know the total from both Cs and Ba-137m? Thank you.

con2grad issue of mismatched datafile records and descriptor file

I got the issue of mismatched concen.grd and concen.ctl when my cdump has two species & two levels including the ground level 0. It seems by commenting out the first if branch around line 190 in con2grad.f can fix this problem:
...
!if(depos)then
!write(30,'(a,i2,a,10i6)') 'zdef ',nlvl-1,' levels ...

minor issue with con2grad putting "***" for larger dimensions in concen.ctl

Can fix it by increasing the formatted print width around line 192 of source/con2gard.f, see changes in red
