Below are listed the general steps and sequence for SEED data processing and submission. The steps are divided into 3 sections: data reduction and timing quality control, database population, and sending data to PASSCAL. For more details and examples refer to our documentation.
I. Data reduction and timing quality control
a. Create an organized directory structure for your data
b. Split the multiplexed files into sta.net.loc.chan mseed files
c. Verify data quality Using Q330 log files
d. Check and fix the headers using fixhdr
e. Change endianess and flag/shift timing
f. Modify default fields on your traces to MSEED format
II. Populating the antelope aatabase
a. Create a dbbuild batch file
b. Build the antelope database
c. View your database
d. Create MSEED day volumes and adding them to your database
e. Assign calibration values from calibration table to wfdisc
f. Verify the Integrity of your database
g. Create the dataless SEED
h. Verify the dataless SEED
III. Send Data to IRIS PASSCAL
a. Notify data_group [at] passcal [dot] nmt [dot] edu (data_group) of your intentions
If you have questions regarding why your data must be archived please review the PASSCAL Data Delivery Policy.
Much of the software utilized for processing and archving is part of the Boulder Real-Time Technology Inc, Antelope package. The latest release of Antelope software is available from PASSCAL to IRIS voting member institutions.
PASSCAL maintains a suite of software for a variety of tasks, including data processing and archiving. Please download the latest release of our software and essential packages upon which it depends (e.g. python).
