Processing Seismic Ambient Noise By: Brenda Luna IV (Stage 1
and 2)
Slide 2
Process based on: Processing seismic ambient noise data to
obtain reliable broad-band surface wave dispersion measurements
(2007) G. D. Bensen et. al and Marco Calo, post-doc at UC Berkeley
1)Download data from IRIS: a) For each station download a months
worth of data. - Change instrument rponse paramtres: zz,pp,
constant for transfre function. - Create a new folder with month
you are working with. - Comment this part out when after going
through the code for the first time. 2) Cross correlate data. -
"Corr_stage_1moise_2013.m" - What you need, (in the month folder):
+ Have "Corr_stage_1moise_2013.m" + Modify what Julian Days you are
looking at in "ListJourJulien.asc" - Make sure you write change the
month name. - Will save as ".freb_0.001_frehaut_0.1_z_b" c) To see
what you are doing; - Be in folder with "FicCorrSign.freb_0.001"
and "JAN" (folder with month, this is must optional) 3)Stacking; -
"StackCorr_stage_v4" - You don't have to be in folder with cross
correlations. Be one folder above. - You need to have your list of
stations 4)To visualize stack: "VissuCorrStack -Need
"CorrStack_bM_031.mat" (Cross-stacked stuff).
Slide 3
Data for the month of January from station 060Z [West Palm
Beach, Florida] Original Mean removed Trend removed Step 1: Single
Station Preparation: Transfer
Slide 4
The more stacking that is done the better signal to noise
ratio.
