Re: ASCII to cdump file

In the exec directory there is a program called conmaxv that will calculate the maximum concentration at each concentration grid.

Re: Fukushima Calculation

Please send us the CONTROL files you are using for the calculation along with some description of the procedure you are following.

Re: Compute particle loading in the domain

Please take a look at the MESSAGE file. When you reach the main computation, the MESSAGE file will show a series of outputs that look like the following:
NOTICE main: 1 44039103 125 4.9999949E-02

The last column represents the total mass that the model is computing.

Re: FATAL ERROR: File not found:cdump

You are getting that message because the GUI is trying to find a concentration file that has not been generated. Please make sure you are generating a cdump file with some content on it. The GUI will not close when you close your GS window. It is supposed to continue working so you can do other calc...

Re: Uncertainty along trajectory endpoint

This "noise" function or dispersion/turbulent component is a function of time and ws stdev. The uncertainty, as you mentioned in your comment, increases as you go further back in time. In principle, the concentration mode is just a group of trajectories that have a turbulent component included in th...

Re: Uncertainty along trajectory endpoint

Conceptually it makes sense. However, your 2-D Gaussian noise should reflect the state of the atmosphere. Ideally, you should use the standard deviation of the horizontal wind speed as a measure for the with of your Gaussian distribution. HYSPLIT explicitly calculates the standard deviations in the ...

Re: Problems with ERAInterim data

Please make sure you have all the required meteorological variables in the ARL meteorological file that you created. Use the utility program such as chk_file located in the exec directory to see if the variables exist.
