FrontierPhysics: Heat-Assisted Detection and Ranging

Task input dataset for heat-assisted-detection-and-ranging in FrontierPhysics, hosted by BenchFlow.

This repository preserves the input files from dccc2025/tmp_dataset_hadar at revision 970d6d16874f3668e0d95e32eb5411a01c9ede05, the snapshot pinned by FrontierPhysics PR #183. The scientific inputs and DATASET_CARD.md are unchanged.

Contents

The complete input bundle is approximately 2.13 GB:

• Five DARPA IH Dataset LWIR hyperspectral scenes, each with an ENVI .bsq cube (425,984,000 bytes) and .hdr header.
• Five matching spectral attenuation files in attenuation/.
• Five matching zenith downwelling radiance files in downwelling_radiance/.
• DATASET_CARD.md, with acquisition metadata, array schemas, units, calibration corrections, and citations.

The original directory layout is preserved for use as /root/inputs in the FrontierPhysics task environment. Each scene's cube, attenuation, and downwelling files share a filename stem.

Use a commit revision for benchmark builds. PR #183's environment/hf/build_checksums.txt contains the SHA-256 checksums for all 21 scientific input files. Its environment/hf/inputs.lock selects the repository, and environment/hf/commit_id.txt selects the revision.

The input bundle and scientific documentation were prepared by Cheng Dai / dccc2025. The source repository labels the bundle Apache-2.0; that metadata is preserved here. The cubes come from the DARPA IH Dataset, and their headers retain the original distribution statements. See DATASET_CARD.md for the source citation and atmospheric product documentation.
