  1. (Stage 1 and 2) Processing Seismic Ambient Noise By:Brenda Luna IV

  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 Download data from IRIS: a) For each station download a months worth of data. - Change instrument réponseparamètres: zz,pp, constant for transfère 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).

  3. Step 1: Single Station Preparation: Original Mean removed Trend removed Transfer Data for the month of January from station 060Z [West Palm Beach, Florida]

  4. The more stacking that is done the better signal to noise ratio.
