IHW Comet Halley Infrared Polarimetry: 137 Observations from 1985-1986

NASA's International Halley Watch (IHW) archive includes infrared polarimetry data on Comet Halley. The data collection contains 137 observations submitted by scientists, spanning from September 16, 1985, through June 1, 1986. This subnetwork data was part of a larger, multi-disciplinary archive augmented by spacecraft measurements.

Use Cases

• Analyzing the polarization properties of Comet Halley based on infrared observations.
• Studying temporal changes in the comet's coma and dust based on the 9-month observation period.
• Comparing ground-based infrared polarimetry data with spacecraft measurements mentioned in the description.
• Researching comet composition and dust grain properties based on polarimetric data.

Strengths

• Contains 137 specific observations.
• Covers a defined 9-month time range from 1985-09 16 to 1986-06-01.
• Data is part of a curated NASA archive with discipline specialist evaluation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known, but the specific variables and measurement details are not described.
• Data is historical, with the last metadata update listed as 2026-03-13; freshness should be verified.
