Data and code for "Frenetic Accessibility as a Cloud-Regime Transition Diagnostic"

Reproducibility deposit for the manuscript "Frenetic Accessibility as a Cloud-Regime Transition Diagnostic." Contains the Python analysis and figure-generation code, intermediate .npz caches (coarse-grained regime-label time series and per-region transition summaries for four months), machine-readable toy-model output tables, and a frozen, checksummed manifest pinning the exact public ISCCP-Basic HGG satellite granules used (992 granules, 3.02 GB; the raw NetCDF is not included). The caches reproduce the toy-model results and the satellite cross-regime, obstruction, and overdispersion analyses without the multi-gigabyte download. The satellite input is the NOAA ISCCP-Basic H-Series Climate Data Record, obtained anonymously from the NOAA Open Data Dissemination S3 bucket noaa-cdr-cloud-properties-isccp-pds. See README.md for per-script documentation, region boxes, and download instructions; SHA256SUMS.txt lists checksums for every file.
