Concise Description
A Python module that converts between AACGM coordinates and an adjustable magnetic coordinate system based on the location of the polar cap boundary.
Description
OCBpy is a Python module that converts between AACGM coordinates and a magnetic coordinate system that adjusts latitude and local time relative to the Open Closed field line Boundary (OCB), Equatorial Auroral Boundary (EAB), or both. This is particulary useful for statistical studies of the poles, where gridding relative to a fixed magnetic coordinate system would cause averaging of different physical regions, such as auroral and polar cap measurements. The coordinate system methodology is described in Chisham (2017). Boundaries must be obtained from observations or models for this coordinate transformation. Several boundary data sets are included within this package, including northern hemisphere boundaries from the IMAGE satellite, northern and southern hemisphere OCBs from AMPERE, and single-point boundary locations from DMSP.
