Reliability scores for pre-emergence bare-soil maps (Copernicus)

CLMS VLCC Bare Soil Before Confidence Layer (CPBSBCL) Europe 10m yearly V1
biosphere ESA ESA Copernicus active
In plain English

What it measures. Expresses how uncertain the bare-soil-before estimates are, in days (1 to 80), based on the confidence in detected crop emergence and harvest dates.

How it's made. ESA Copernicus generates it annually at 10-metre resolution across the EEA-38 countries as a quality companion to the bare-soil-before layer.

How & where you'd use it. A supporting quality measure that tells analysts how much to trust the timing of pre-planting bare-soil periods.

Official description

The Bare Soil Before Confidence Layer (CPBSBCL) is an ancillary dataset accompanying the CPBSB layer. It quantifies the uncertainty of the bare soil period before the emergence of the main annual crop, expressed in days (range: 1–80). The uncertainty is based on the uncertainty of the emergence and/or harvest events that define the bare soil period. Emergence events occurring after the calendar year that marks the end of the bare soil period will not be included in the uncertainty calculation. This dataset is provided annually starting with 2017 in 10-metre rasters (fully conformant with the EEA reference grid) in 100 × 100 km tiles covering the EEA-38 countries. The HRL Bare Soil Before Confidence Layer product is part of the European Union's Copernicus Land Monitoring Service. This dataset includes data from the French Overseas Territories (DOMs).
