This page talks about the steps involved in replicating the track files obtained from the radar site. The Titan params file used for this purpose is also a pre-existing params file present in the data obtained from the radar site. It is believed that this pre-existing Titan params file is used to generate these track files. The purpose of this process is to check if that is true or not. The various parameters in this params file are kept unchanged to see if exactly the same set of track files are produced after running Titan.

Elements Used in the Process:

Data from storm with both complex and simple track numbers 15 occurring on 2017/07/09 at 19:51:27 are compared.

Application Used: Titan. Since a pre-existing params file is used, there is no need to generate the params file.

Input Used: Gridded cartesian radar data in mdv format.

Output Produced: A new set of storm track files in .th5 format. These new track files should contain exactly the same information present in the pre-existing track files.

Generating The ASCII File Using Tracks2ASCII Application: The application Tracks2Ascii is used to extract the information present in both the pre-existing .th5 files and the new set of .th5 files out into respective .txt files in ASCII format. The information in the two sets of ASCII files should be exactly the same.

Description of the Process:

Generate the pre-existing track files: As pre-existing, already present.

Generate the ASCII file (set 1) from these pre-existing track files using the Tracks2Ascii application:

Generate a new set of track files using the pre-existing Titan params file:

Generate the ASCII file (set 2) for these new set of track files using Tracks2Ascii application:

Compare the set 1 ASCII files with the set 2 ASCII files to see if they are exactly the same. If they are the same, it means the pre-existing Titan params file was used to generate the pre-existing track files. If not, a different Titan params file was used. The question is, where is that params file ?
