PRASSADCO processing of the Polar PWI-HFWR data

Processing of HFWR calibrated waveforms, using University of Iowa local reader program and data archives. PRASSADCO is a computer program designed to analyze multicomponent measurements of electromagnetic waves. It implements methods used to estimate polarization and propagation parameters, such as the degree of polarization, sense of elliptic polarization and axes of polarization ellipse, the wave vector direction. The results can be represented in different visual and numerical formats.

Instructions:

1. Download files README.txt, hfwrprassadco.tar, guide.pdf
2. Untar the distribution file: tar -xvf hfwrprassadco.tar
3. Move and/or rename the distribution directory hfwrprocessing to your location
4. Following README.txt set the path variables and run the processing chain

Distribution:

• README.txt ... Instructions
• hfwrprassadco.tar ... Scripts, test output and IDL library of PRASSADCO and HFWR reading procedures.

Processed data sets:

• Results for the entire data set of 2 kHz low resolution data
• Results for the entire data set of 16 kHz low resolution data
• Results for the entire data set of 25 kHz high resolution data
• Results for the list of chorus events of LeDocq et al., Geophys. Res. Lett., 25, 4063�4066, 1998.
