Dear All,
1. Does the following text mean that the user can not simulate the concentration of materials with 10 m-AGL source term release height by using GDAS data?
"For historical reasons, the model sets a minimum value for the PBL height. The default is 250 m and it is related to the typical vertical resolution of the meteorological data used to run HYSPLIT [e.g., Global Data Assimilation System (GDAS) or Eta Data Assimilation System (EDAS)]"
2. Can use the uncertainty of the concentration calculation instead of concentration calculation error?

1. No
2. I don't understand this question.

Re: GDAS data limitations
please forgive me for my unsuitable question.
My question is: could I use the results of the ensemble section in the GUI instead of concentration calculations error?
and if I can't, is there any other solution to finding concentration calculation error, like another codes that express the calculation errors?

Re: GDAS data limitations
Yes, the various concentration ensembles give an estimate of the error. There is no code itself that gives the error.
