Models: Stratus and Nimbus
Model Overview
| Model Name | Status | Base Price (EUR/km²) | Data Product | Resolution | Required Inputs | Optional Inputs |
|---|---|---|---|---|---|---|
| Stratus-2 | available | €0.20 | Level-2A | 10 m | Sentinel-1, Sentinel-2, Landsat 8/9 | None |
| Stratus-3 | available | €0.20 | Level-2A | 10 m | Sentinel-1, Sentinel-2, Landsat 8/9 | None |
| Stratus-2 Fast | available | €0.18 | Level-2A | 10 m | Sentinel-1, Sentinel-2 | Landsat 8/9 |
Stratus-3 is production-available and currently follows the same pricing bands as Stratus-2. See Model pricing for rates. Stratus-2 Fast is production-available and supports optional Landsat 8/9 input. In latency-sensitive workflows, leaving Landsat unselected can reduce time to full availability. Stratus-2 (No Snow) is planned for deprecation and is not recommended for new orders.
Display Names vs API Values
Docs and dashboard screens use display names like Stratus-2 and Stratus-2 Fast.
API requests use Model values (for example Stratus2, Stratus2Fast) and these can differ from display punctuation.
Always use the canonical values returned by GET /api/tasking/models (or the OpenAPI spec) when building API payloads.
Available Models
Stratus-2
Stratus-2 is the original ClearSKY Vision cloud-removal model and the ‘Product’ winner of the CASSINI Challenges. It leverages data from Sentinel-1 (ascending and descending), Sentinel-2, and Landsat 8/9 to produce cloudless, multi-spectral Sentinel-2 imagery. Thanks to its advanced data cleaning capabilities, Stratus-2 excels during periods with haze, thin cirrus clouds, and cloud shadows, delivering clear and accurate images. Its SAR (Synthetic Aperture Radar) capabilities make it particularly powerful in northern countries, where high SAR revisit frequencies significantly enhance image timeliness and provide more up-to-date imagery.

Stratus-3
Stratus-3 is available in production and delivers cloudless, multi-spectral Sentinel-2-compatible imagery for operational monitoring workflows. It uses the same core input constellation and output contract as Stratus-2.

Stratus-2 Fast
Stratus-2 Fast is optimized for lower-latency cloudless delivery while preserving Sentinel-2-compatible outputs. Sentinel-1 and Sentinel-2 are always required, while Landsat 8/9 is optional. Keeping Landsat unselected can improve delivery speed in latency-sensitive workflows; selecting Landsat can improve usable coverage in some areas at add-on cost.
