About the Project

CHMAP is a python package focused on the detection, mapping, tracking, and general analysis of coronal holes in the solar corona.

CHMAP includes methods for:

Data Acquisition
Data Reduction
Limb Brightening Correction
Inter-Instrument Scaling
Flexible Map Creation
Coronal Hole Detection
Coronal Hole Tracking

Although CHMAP was designed for analyzing coronal hole evolution from seconds to years, many of the database, image processing, and mapping procedures are relevant a broad range of solar features and scientific analysis.

A research paper describing the initial release of CHMAP and some applications is currently in preparation. In the meantime, if you use CHMAP code or concepts in your own work, please refer to our prior work on this topic (Caplan et al., 2016) and cite the corresponding Zenodo release for CHMAP: .

The development of CHMAP was primarily supported by the NASA Heliophysics Guest Investigators program (grant NNX17AB78G). Additional support is from the Heliophysics Supporting Research program (grants 80NSSC18K0101 & 80NSSC18K1129).
