THIES CLIMA 3D Stereo Disdrometer

Overview

The THIES CLIMA 3D Stereo Disdrometer uses stereo imaging to analyse precipitation particle size, velocity and spatial shape, and identifies non-hydrometeors such as insects and seeds. Temperature measurement, Ethernet and RS-485 communication and internal SD-card storage support precipitation-spectrum and microphysics research.

Key features

• Stereo images provide particle dimensions, motion and shape information for precipitation analysis.
• Covers 0.08–40 mm particle sizes and 0.2–20 m/s velocities, from small precipitation particles to larger hail.
• Distinguishes non-hydrometeors to help exclude insects, seeds and other foreign objects.
• Integrated Pt100 temperature measurement accompanies precipitation intensity, type and spectrum data.
• Ethernet, RS-485 and internal SD-card storage; TCP/IP supports up to five clients.
• The 2026 fact sheet specifies particle-image output: up to four images per telegram, for particles in the focus area.
• Embedded Linux supports SSH, SFTP and SCP access, with remote firmware updates over Ethernet.
• Standard camera heating and extended-heating variants suit different icing risks and power supplies.

Technical specifications

Model and configuration differences

System configuration and options

• Optional instrument stand 4.3187.61.x00; match pole diameter and site foundation to the installation.
• The manufacturer lists LNM View and Thies CLIMA Viewer tools; select software for the communication and analysis requirements.

Applications

Precipitation microphysics, meteorological stations, weather-radar validation and rain, snow and hail particle-spectrum observations.

Selection

Choose standard or extended heating for the available power supply and icing conditions, then specify network access, storage and particle-image requirements.
