Cloud-free Sentinel-2 imagery, on demand
ClearSKY fuses optical and SAR observations to reconstruct cloudy Sentinel-2 scenes into analysis-ready imagery for GIS workflows, machine learning and visualization.ClearSKY reconstructs cloudy Sentinel-2 scenes with optical + SAR fusion, ready for GIS workflows, ML and visualization.
What changes after the clouds
A monitoring workflow built around usable pixels.
ClearSKY turns cloudy satellite observations into dependable imagery for recurring monitoring, from reconstruction and delivery to ordering, analysis, and integration.
Reconstruction
Optical & SAR AI Fusion
Our AI combines optical and radar (SAR) imagery to reconstruct missing Sentinel-2 data, preserving spectral integrity and enabling 100% analysis-ready, cloud-free images.
Operations
Near Real-Time Delivery
Order cloud-free Sentinel-2 imagery on demand, processed in near real time without interpolation.
Ordering
Seamless Workflow
Monitor exact AOIs or selected grid coverage to fit your needs, down to 0.5 km² for Field Monitoring. Skip manual cloud masking and get analysis-ready data instantly.
Cadence
Continuous Monitoring
Access flexible revisit speeds from daily to weekly. Cloud-free imagery is excellent for tracking NDVI, deforestation, land cover changes, and other environmental metrics.
Analysis-ready data
Less preparation. More usable signal.
Avoid the hassle and jump straight into actionable insights with perfectly preprocessed, analysis-ready imagery. No more time-consuming cloud masking or calibration.
Trusted in production
Trusted by leading organizations
ClearSKY is used by teams that need dependable satellite imagery for operational monitoring.
Order via API or dashboard
Use the dashboard for quick ordering and exploration, then automate the same workflow in production via API.
Monitor exact AOIs
Best for farms, research plots, scattered fields, and custom boundaries. Draw an AOI or import geometry and monitor exactly what you need.
Flexible order setup
Configure sources, cadence, timeframe, and outputs. Results stay available so you can pull exactly what you need later, via dashboard or API.
- Draw or upload an AOI polygon
- Set frequency (daily → weekly)
- Choose timeframe + outputs
- Add to cart, order, then automate repeats
Nimbus base pricing from 1 November 2026 · required inputs included
€1.82/km²/mo · 0.5 km² minimum
Optional Landsat 8/9 adds 10% to the selected model price.
Monitoring cadence
Cloud-free Sentinel-2 monitoring without the quiet gaps.
Get cloud-free Sentinel-2 imagery on your schedule, from daily to weekly revisit rates. No more gaps in monitoring due to cloud cover, just uninterrupted satellite insights tailored to your needs.
Near real-time evidence
Today's imagery should reflect today's conditions.
Our near real-time data fusion uses only current and past sensor inputs, avoiding future data and model-based interpolation. The full-width graph makes that temporal behavior easier to inspect.
Fusion walkthrough
Multi-sensor fusion in action
Watch cloudy optical and SAR observations become one cloud-free output using only observations available at that point in time.
