Full descriptionAs part of the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP), long-period magnetotelluric time series data were collected in the Musgraves Province between 2016 and 2018. Level 1 concatenated, resampled, rotated NetCDF time series data from Earth Data Logger sites located in Western Australia are presented.
LineagePython was used for the generation of the Level 1 concatenated, resampled, rotated NetCDF time series products. The generation of these files was done in two stages:
The raw time series were checked for gaps in continuity and if gaps were found, the problematic stations were segregated for stage 2 processing. The stations that passed the initial checks were merged into concatenated (over all days of recording) ASCII files (EX, EY, BX, BY, BZ). These ASCII files were then converted into a temporary binary file to accelerate the subsequent I/O operations. The binary data were read in, downsampled to 1 Hz and rotated by the rotation angle in the header metadata. The outputs are converted into a single NetCDF file per station and all the metadata attributes (based on https://doi.org/10.1080/14432471.2019.1600210) are added to the header.
For those stations that did not pass the initial "continuous time series" test, the user manually determined which days had continuous time series without any gaps. The stage 2 processing then performs the same operations as the stage 1 processing, but only on the selected days.
