What is ClearSKY?
Who We Are
ClearSKY Vision builds operational Earth-observation products for teams that need reliable optical imagery even when cloud cover is persistent. Our goal is to increase usable revisit frequency by combining multiple satellite inputs and delivering analysis-ready outputs that slot into existing Sentinel-2 workflows.
What ClearSKY Is
ClearSKY provides cloud-free, multi-spectral Sentinel-2-compatible imagery.
The platform fuses optical and SAR observations to address:
- cloud cover,
- cloud shadows,
- haze and related atmospheric artifacts,
- missing optical pixels.
You can order both historical and recurring data, and access it through dashboard and API workflows.
What "Cloud-free" Means Here
Cloud-free in ClearSKY means reconstruction, not only masking or mosaicking.
Instead of only hiding cloudy pixels, the pipeline reconstructs usable optical outputs from available multi-sensor evidence, while preserving compatibility with Sentinel-2 style processing workflows.
ClearSKY processing is designed for near-real-time usage and does not use future scenes to generate today's outputs.
What You Can Do
- Order with polygons, tiles, or minitiles.
- Choose revisit cadence from daily to weekly.
- Start from small areas (minimum order area is 0.5 km2).
- Download with API or dashboard, depending on your operating model.
- Choose a specific model and output configuration (TOA and/or BOA, depending on model support).
Why Teams Use It
- Better monitoring continuity in cloud-prone regions.
- Less manual cloud-cleaning overhead.
- Easier integration into GIS, ML, and reporting pipelines.
- Flexible ordering and delivery modes for both ad-hoc and production operations.
