Data Product Overview

Purpose​

Use this page to understand what ClearSKY outputs are and how to choose stable defaults for production workflows.

ClearSKY delivers cloudless Sentinel-2 compatible outputs for monitoring across historical and recurring time ranges.

Model Families​

  • Stratus: harmonized BOA-focused workflow with stable core bands.
  • Nimbus: Sentinel-2 compatible workflow with broader band support options.

For model-by-model details, see Models: Stratus and Nimbus.

Output Behavior​

  • Outputs are multi-spectral GeoTIFF products.
  • Projection, resolution, and band selection are chosen at request time.
  • Derived index expressions can be requested in processing flows.

For canonical technical values, use Data specification.

Practical Production Defaults​

  • Prefer UTM EPSG output when downstream stack supports it.
  • Keep Model and SatelliteConstellations consistent inside a single time-series.
  • Run availability checks before large recurring download jobs.
  • Prefer explicit band lists in automation instead of broad discovery values.

Common Failure and Fix​

  • Failure: time-series comparability drifts because settings changed between runs.
  • Fix: version your request template and enforce fixed model/constellation/projection defaults per pipeline.
