Particle number matter

Post by solkim » August 29th, 2019, 1:58 am

Dear HYSPLIT Users and HYSPLIT Masters

I’ve operate HYSPLIT model to predict radionuclides dispersion.
I ran HYSPLIT in 2 way to simulate dispersion model more realistic.

Setup condition of way 1 is like below.

Code: Select all

 &SETUP
 tratio = 0.75,
 initd = 0,
 kpuff = 0,
 khmax = 9999,
 kmixd = 0,
 kmix0 = 250,
 kzmix = 0,
 kdef = 0,
 kbls = 1,
 kblt = 0,
 conage = 48,
 numpar = 2500,
 qcycle = 0.0,
 efile = '',
 tkerd = 0.18,
 tkern = 0.18,
 ninit = 1,
 ndump = 0,
 ncycl = 0,
 pinpf = 'PARINIT',
 poutf = 'PARDUMP',
 mgmin = 1440,
 kmsl = 0,
 maxpar = 10000,
 cpack = 1,
 cmass = 0,
 dxf = 1.0,
 dyf = 1.0,
 dzf = 0.01,
 ichem = 0,
 maxdim = 1,
 kspl = 1,
 krnd = 6,
 frhs = 1.0,
 frvs = 0.01,
 frts = 0.1,
 frhmax = 3.0,
 splitf = 1.0,
 /
In the procedure running the way 1, I got particle puff limit warning.
So i’ve changed maximum particle number like below and this is the way 2.

Code: Select all

 &SETUP
 tratio = 0.75,
 initd = 0,
 kpuff = 0,
 khmax = 9999,
 kmixd = 0,
 kmix0 = 250,
 kzmix = 0,
 kdef = 0,
 kbls = 1,
 kblt = 0,
 conage = 48,
 numpar = 2500,
 qcycle = 0.0,
 efile = '',
 tkerd = 0.18,
 tkern = 0.18,
 ninit = 1,
 ndump = 0,
 ncycl = 0,
 pinpf = 'PARINIT',
 poutf = 'PARDUMP',
 mgmin = 1440,
 kmsl = 0,
 maxpar = 70000000,
 cpack = 1,
 cmass = 0,
 dxf = 1.0,
 dyf = 1.0,
 dzf = 0.01,
 ichem = 0,
 maxdim = 1,
 kspl = 1,
 krnd = 6,
 frhs = 1.0,
 frvs = 0.01,
 frts = 0.1,
 frhmax = 3.0,
 splitf = 1.0,
 /
I ran HYSPLIT in the way 2 and I got no warning about particle number but meteo error like below.

Code: Select all

 WARNING metpos: no meteo data at current time -     62885580
Of course there was same meteo error in the way 1 method too.

Here is question, From the perspective of particle number, do you think I ran HYSPLIT properly?

Can you please share your CONTROL file with us?

Because of attachment error.
I attachment CONTROL file in the message board not file format.

here is my CONTROL file.
