Microwave Single Scattering Properties Database (Horizontally Aligned Aggregates of Dendrites)

The database contains physical and microwave single scattering properties of horizontally aligned frozen hydrometeors as large as 11 cm in diameter. 

A description of the aggregation model used for particle generation can be found in:
Leinonen, J., and  Szyrmer, W. (2015),  Radar signatures of snowflake riming: A modeling study, Earth and Space Science,  2,  346– 358, doi:10.1002/2015EA000102.
The code used for particle generation is freely available at: https://github.com/jleinonen/aggregation

The scattering properties of particles were computed using discrete dipole approximation using ADDA software package (https://github.com/adda-team/adda)

Terminal velocity of snowflakes was computed using 4 hydrodynamical models that were implemented as a part of snowScat library (https://github.com/OPTIMICe-team/snowScatt)

Approximately one half of the snowflake structure files and one quarter of scattering properties (for X, Ku, Ka and W band) were generated for the publication of Leinonen and Szyrmer (2015). The remaining part of the dataset was generated using the ALICE High Performance Computing Facility at the University of Leicester.
