Description

Hello.
I can plot FLEXPART output with quicklook developed by radekholfman. However, I want to do some calculations with output data. For example,I want to determine area the activity concentration in the air bigger than 1E+5 at the end of 5th day at 23.00 in my sutdy area with a GIS software. But output data are binary format. There is a subroutine developed by Stohl to read Flexpart output. But I don't understand how I can use it. Is it possible to output data convert from binary format to readable/editable format with these codes? if so, how can I do?

I have one question too. If direction is forward, ind_source and ind_receptor are 1, and input unit is kg, output unit is ng/m3 (according to table 2 in FLEXPART82 document). My input unit is Bq an the other variables are same, so, my output unit is pBq/m3, isn't it?

You will need to use a programming language such as python or Fortran to work with the data. Both RH's python code and the Stohl et al Fortran code can serve as a base. As FLEXPART produces large amounts of output, a compressed binary format is used. It is not recommended to save this in a simple text format.

Your assumption about units is right.

Also, please ask support questions first through the Flexpart mailing list. Tickets should mainly be used for problems that need the attention of developers.
