This dataset contains P-to-S converted seismic receiver functions from stations across Africa. Receiver functions are P-to-s filtered at frequencies to observe discontinuities in the mantle transition zone. Receiver functions have been used to look at topography on the mantle discontinuities and scatterers in the mid-mantle: Boyce, Alistair, and Sanne Cottaar.

Note: All Seismic data used is freely available from the Incorporated Research Institutions for Seismology (https://ds.iris.edu/ds/nodes/dmc/), GeoForschungZentrum (http://geofon.gfz-potsdam.de/), French national (http://seismology.resif.fr/) and Institut de Physique du Globe de Paris (http://geoscope.ipgp.fr/index.php/en/) datacenters. The attached data is stored in .PICKLE files. Scripts used to process this data, and use this data can be found in our toolkit SMURFPy: https://zenodo.org/record/4337258#.X_6-6y2l0Wo . This relies heavily on the ObsPy library https://docs.obspy.org The receiver functions are stored in separate folder for P- receiver functions, PKP- receiver functions, and PP-receiver functions. Subfolders represent different stations, and are named by #networkID.#stationID. Some folders are empty as none of the receiver functions pass quality control. Initial processing includes the data download, data rotation, filtering and windowing, and iterative deconvolution in the time domain. Different versions are created at different frequency bands as defined in the README file. Automatic Quality Control is applied, based on signal-to-noise ratios, receiver function recovery measures, and peak amplitudes in the receiver function (outside of the main P peak). We provide various time-to-depth conversions for the data. Details on how these are stored are provided in the readme. Models used are PREM (Dziewonski & Anderson 1981), ak135 (Kennett et al. 1991), AF2019CR (Celli et al. 2020), AFRP20CR (Boyce et al. 2021), SEMUCBCR (French & Romanowicz 2014), SGLOBEraniCR (Chang et al. 2015), SL2013SV (Schaeffer & Lebedev, 2013). Data resulting from NERC grant NE/R010862/1 High-resolution seismic constraints to reveal mid-mantle processes.
