"Imaging the extension of deep carbon stocks at the catchment-scale with complex electrical conductivity"  submitted to GRL by 
by Flores Orozco1, A., Gallistl, J., Gilfedder, B., Katona, T., Frei, S., Strauss, P., and Blöschl, G.

The file contains three subfolders:
SIP1 - refers to the multi-frequency complex conductivity data collected along the line SIP 1. The measurements were collected using 64 electrodes with 1 m spacing between them. Each file in the subfolder refers to the data at different frequencies, with the frequency indicated in the name of the file (in mili Hertz). The folder also contains a file with the coordinates of the electrodes.

E1 - refers to the complex conductivity data collected along the exploration line. The measurements were collected with 677 electrodes, and 1 m spacing. The file contains repeated quadrupoles corresponding to those readings with overlapping segments in the roll-along survey. 

Lines E1 and SIP1 are perpendicular to each other, and measurements were collected with a DAS-1 instrument from MultiPhase Technologies.  

M1 - contains the raw data of the 27 lines collected as part of the mapping survey. Measurements were collected with a syscal switch pro 72 from IRIS instruments. There are two files, one with the data and one for the coordinates of each profile. All measurements were collected in the time-domain, with a square wave using a pulse length of 500 ms, and sampling of the decay curve with 19 windows with 20 ms duration for each window and 20 ms waiting time between the current switch-off and the collection of the first window. The raw data contains readings of the chargeability (m) measured in each window and the duration. 
In particular, the data comprises:
1) 5 long lines (Mapping_l1n to Mapping_l5n) roughly with an orientation SW-NE with 72 electrodes and 1 m spacing between electrodes and 5 m between lines. These lines are parallel to SIP1 line 
2) 17 short lines in direction SW-NE (Mapping_s1n to Mapping_s17n) with 72 electrodes each and a spacing of 0.5 m between electrodes and lines. These lines are parallel with the SIP1
3) 5 lines with roughly a direction SE-NW (Mapping_p1 to Mapping_5p) with 72 electrodes each and a spacing of 1 m between electrodes and 5 between lines. 

The measurements of a few reciprocal data are indicated with the "r" in the name of the file (for instance Mapping_l1r). Reciprocal measurements are the repetition of the normal measurements after interchanging the electrodes used for current and potential dipoles. These reciprocal measurements were collected for statistical analysis of the misfit between normal and reciprocal readings to quantify data-error.
