CloudSci builds advanced optical particle measurement instruments that use digital holography, multi‑angle scattering, and on‑board machine‑learning to deliver real‑time size, concentration, and morphological data for atmospheric aerosols, cloud ice crystals, and bioaerosols. Their Passive Aerosol Imager provides open‑path, in‑situ imaging of coarse particles, while the Airborne Multi‑Angle Aerosol Size Spectrometer offers high‑resolution size distributions for aircraft deployments, enabling precise, calibrated data for research, air‑quality monitoring, and climate studies.

Problem
Accurate measurement of atmospheric particles—especially coarse-mode aerosols, cloud ice crystals, and bioaerosols—is limited by traditional sampling instruments that rely on inlet lines, suffer from sampling artifacts, and lack real‑time imaging or chemical analysis capabilities.
Solution
CloudSci develops advanced optical particle measurement systems that combine digital holography, multi‑angle scattering, and computational imaging to capture high‑resolution size, concentration, and morphological data without direct sampling. Their Passive Aerosol Imager (PAI) uses an open‑path triggered holographic sensor to image coarse particles in situ, while the Airborne Multi‑Angle Sizing Spectrometer (AMASS) provides real‑time, high‑resolution size distributions for aircraft‑mounted deployments. Both instruments integrate modern optics, custom electronics, and on‑board machine‑learning algorithms for automated particle detection, sizing, and classification, delivering calibrated data streams that can be directly used in atmospheric research, air‑quality monitoring, and climate studies.
Target Audience
Primary customers are atmospheric research institutions, government air‑quality agencies, and aerospace research programs that require precise, real‑time aerosol and cloud particle measurements for field campaigns, aircraft studies, and climate modeling.
Features
- Open‑path digital holography in the PAI eliminates sampling lines, reducing artifacts and preserving particle integrity
- Real‑time on‑board hologram processing and machine‑learning based particle detection for immediate size and concentration outputs
- Multi‑angle scattering optics in AMASS deliver high‑resolution size bins and particle waveform capture within a standard PMS canister form factor
- Configurable size ranges (4 µm to >100 µm for PAI; wide aerosol size spectrum for AMASS) and concentration handling
- Robust mechanical and electronic design for field and airborne deployment, including aircraft‑compatible mounting
- Integrated data pipelines that output calibrated particle metrics for downstream scientific analysis
