MPD-THERMO

MicroPulse DIAL Thermodynamic Profiling Study

1 June 2026 - 30 September 2026

Lead Scientist: Scott Spuler

Observatory: SGP (Southern Great Plains)

The MicroPulse DIAL (MPD) is a cost-effective, active remote sensing instrument for continuous thermodynamic profiling in the lower troposphere (100 m to 6 km). This proposal focuses on validating its newly developed temperature capability and the Multi-Pulselength Mode (MPM) operating technique. The MPM technique was developed to overcome near-range blind zones, enabling profiling closer to the surface. The validation experiment, planned for the SGP central facility for 90 days between June and September 2026, will compare observations from several MPD units against established techniques –– radiosondes, microwave radiometer, infrared spectrometer, and the SGP Raman Lidar –– to develop confidence in the measurement and confirm its potential to meet or exceed requirements for continuous, high-resolution thermodynamic data.
