ARTS Microwave Single Scattering Properties Database (Oriented Particles)

A 2019 database contains microwave and submillimeter wave single scattering data for azimuthally randomly oriented frozen hydrometeors. It includes data for one aggregate and one pristine ice crystal habit, across 35 frequencies from 1 to 886 GHz and three temperatures (190, 230, 270 K). The dataset was created by researchers at Universität Hamburg using the discrete dipole approximation method.

Use Cases

• Modeling polarized radar backscatter based on oriented ice particle scattering properties.
• Simulating passive microwave brightness temperatures for satellite remote sensing based on hydrometeor scattering data.
• Developing retrieval algorithms for ice cloud properties based on scattering data across 35 microwave frequencies.
• Validating radiative transfer models based on single scattering properties of oriented frozen hydrometeors.

Strengths

• Includes data for two distinct ice crystal habits (aggregate and pristine).
• Covers a broad frequency range of 35 points from 1 to 886 GHz.
• Provides scattering properties at three specific temperatures: 190, 230, and 270 K.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.

Collection Method

Data were calculated using the discrete dipole approximation method (DDA) in combination with a self-developed orientation averaging approach.
