Method synopsis

Continuous measurement of specific differential phase (KDP) using slanted W-band polarimetric radar to detect signatures of dendritic growth and secondary ice production in snow. Radar operated at 40° elevation to sample the dendritic growth layer and measure polarimetric variables.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Investigating KDP signatures inside and below the dendritic growth layer with W-band Doppler radar and in situ snowfall camera (2025), Atmospheric Chemistry and Physics. Implementations in other papers (listed below) may differ.

1. Deploy LIMRAD94 W-band radar
   LIMRAD94 was mounted on a novel cold-temperature scanning unit at 2995 m altitude at Rocky Mountain Biological Laboratory (RMBL), positioned 525 m from nearest ARM Mobile Facility (AMF2) and VISSS location. Operated at 40° elevation with 151° azimuth towards VISSS, AMF2 and CSU X-band radar.
