This repository contains scripts and data for validating the Michigan Geospace model based on the Space Weather Modeling Framework (SWMF). The SWPCTEST directory must be placed within an installed SWMF source code directory and have access to SWMF's Makefile.def file. The deltaB directory contains observations and SWMF model results of the magnetic disturbances at 12 magnetometer stations for the six SWPC challenge events that were run by CCMC. See deltaB/README for more detail. See A. Pulkkinen et al. 2013, Space Weather, 11, 369, doi:10.1002/swe.20056 Event specific information, such as start and stop times, are contained in "event_list.txt". Files common to each simulation can be found in the Inputs directory. Event-specific input files, such as solar wind inputs and satellite trajectory files, are found in the Inputs/event[#] directories. Additional events can be added by adding new entries to event_list.txt and creating a corresponding Inputs/event[#] directory. DSCOVR data can be obtained from https://www.ngdc.noaa.gov/dscovr/ (POP, M1M, F1M) ACE data can be obtained from https://izw1.caltech.edu/ACE/ASC/level2/ (ACE_Mag_data 16s: year, dy, hr, mn, sc, Bgse_x,y,z), (ACE_PLASMA_data 64s: year, dy, hr, mn, sc, H+ dens, temp, velGSEx,y,z, GSE_x,y,z) The Idl directory contains scripts to evaluate the results and calculate skill scores both for direct dB/dt and power law fit a(dB)^p. See Idl/README for more detail. See G. Toth et al. 2014, J. Geophys. Res., 119, 310, doi:10.1002/2013JA019456 REQUIREMENTS: SWPCTEST is designed to run on NASA's Pleiades machines. The following system modules must be loaded via "module load <package>" syntax: python/2.7.6 (or newer) idl/8.1 (or newer) USAGE: To execute the test, install the SWMF in the usual manner. Then, enter the SWPCTEST directory and type make help to see the available options. To run the code for all 6 events type make test To run a subset of events, type make test EVENTS=2,3,5 This will configure and compile the SWMF, create separate run directories and copy input files for each event, and submit the simulations to the run queue. Note that as of now, the suite is set up to execute on the NASA Pleiades super computer. At this point, the user must wait for the simulations to finish. Upon completion, the user should return to the SWPCTEST directory and type make check This will then collect the simulation results into the deltaB/Results directory for each event. Metrics are then calculated and saved. In each results directory (deltaB/Results/Event*), a text file is generated with probability of detection (POD), probability of false detection (POF), and Heidke Skill Score (HSS) for high and mid latitude magnetometer groups for a variety of dB/dt thresholds. These same numbers are calculated for the results obtained for the SWPC selection study led by CCMC. This allows for a comparison of the current version of the code with the version originally submitted to SWPC. A summary table that contains the metrics for all events and stations together is written to the results directory. Finally, the results and metrics are archived in compressed tar file.
