- Description:
- In this study, we show that coronal mass ejection (CME) simulations conducted with the Space Weather Modeling Framework (SWMF) can be assimilated with SOHO LASCO white-light (WL) coronagraph observations and solar wind observations at L1 prior to the CME eruption to improve the prediction of CME arrival time. L1 observations are used to constrain the background solar wind, while LASCO coronagraph observations filter the initial ensemble simulations by constraining the simulated CME propagation speed. We then construct probabilistic predictions for CME arrival time using the data-assimilated ensemble. Scripts in this work are written in R, Python and Julia.

- Description:
- This data set supports the published four-component integration problem using real-world weather forecasts from the European Centre for Medium-Range Weather Forecast and a simulated linear spring--mass--damper system excited by wave elevation. Each component in the spring--mass--damper system is monitored with techniques of differing accuracies representative of marine-type health uncertainties. Weather forecast uncertainty is included using weather predictions of significant wave height and peak period up to 10 days out. As well as their exact values, different test cases include the spring, mass, and damper being modeled as noisy sensors representative of sensors onboard a vessel, as well as the spring being modeled as a visually-inspected system component reflective of human impact onboard a vessel. Complete details are given in the referenced paper; this data set represents the inputs to the machine learning classifiers discussed.

- Description:
- Data were collected to test theories advanced during a Contested Case Hearing to expand treatment capacity of the City of Brighton wastewater treatment facility. The lake historically developed nuisance blooms of cyanobacteria associated with excessive phosphorus and nitrogen limitation. The new wastewater treatment facility reduced phosphate discharge and provided increased concentrations of nitrate. A case study narrative describes the scientific and legal aspects of the case. Data collection and analysis pointed to the presence of a cryptic source of phosphorus income other than from the influent streams, possibly from undocumented septic waste discharges.
