Data for A Hybrid Fluxgate and Search Coil Magnetometer Concept Using a Racetrack Core

David M. Miles
The data is raw measurements from a prototype magnetic field instrument. The data was all captured in a laboratory setup and is intended to demonstrate the utility of the instrument concept to future satellite and rocket applications. There are also a series of matlab scripts which import and process the data to create the figures in the accompanying manuscript.

High spatial resolution top-down SO2 and NOx emissions over China

Zhen Qu, Yi Wang, Jun Wang & Daven K Henze
Accurate air quality simulation and forecast require timely-updated emission inventory. Compared with the bottom-up approach that has at least one-year time lag, the top-down approach that uses satellite observations of atmospheric composition to estimate emissions can provide timely emission inventory. We integrate SO2 and NO2 observations from the Ozone Monitoring Instrument (OMI) Ozone Mapping and Profiler Suite (OMPS) satellite sensors with the GEOS-Chem adjoin model to estimate SO2 and NOx emissions over China (2005-12-01 to...

Concentrations inside schools...

Placing Papers Dataset

Amy H Chen
The market for contemporary authors’ archives in the United States began when research libraries needed to cheaply provide sources for the swelling number of students and faculty following World War II. Soon, the demand for contemporary authors’ archives developed into a multimillion-dollar trade. Writers and their families enjoyed their new opportunity to make money, as did the book dealers and literary agents with the foresight to pivot their businesses to serve living authors. For a...

Non-spatial data for \"Remapping and visualizing baseball labor\"

Katherine Walden
Recent baseball scholarship has drawn attention to U.S. professional baseball’s complex twentieth century labor dynamics and expanding global presence. From debates around desegregation to discussions about the sport’s increasingly multicultural identity and global presence, the cultural politics of U.S. professional baseball is connected to the problem of baseball labor. However, most scholars address these topics by focusing on Major League Baseball (MLB), ignoring other teams and leagues—Minor League Baseball (MiLB)—that develop players for Major League...
