Cloud‑Free Data for Research
Clean, consistent time‑series without cloud‑mask headaches. Spend time on science, not preprocessing.
Trusted by leading organizations




The Cloudy Challenge
Clouds and irregular revisit intervals break experiments and reduce statistical power. Researchers spend more time masking, gap‑filling, and harmonizing than testing hypotheses. Inconsistent mosaics make comparisons across years or sites risky, and student projects often run out of time preparing data. You need a stable, cloud‑free baseline that preserves spectral fidelity so methods are reproducible and results defensible.
- Persistent cloud cover
- Broken / delayed time-series
- Weak audit evidence
Our Solution
ClearSKY fuses optical and SAR satellites using artificial intelligence to reconstruct complete, Sentinel-2 compatible images. You get cloud-free, analysis-ready data via dashboard or API, so you can focus on decisions, not cloud, shadows and image gaps. Spend your budget on questions and models, not on cleaning data—and publish with confidence.
- Reproducible inputs
- Easy to use
- Time saved
Clouds out, decisions in!
Consistent, frequent, gap-free views for hard to reach places.
