Reliability scores for post-harvest bare-soil maps (Copernicus)

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

What it measures. Rates how trustworthy the companion bare-soil-after estimates are, expressed as an uncertainty in days (1 to 80) tied to when crops were detected emerging or being harvested.

How it's made. ESA Copernicus produces it yearly at 10-metre resolution across the EEA-38 countries, as a quality companion to the cropland bare-soil layers.

How & where you'd use it. A technical quality layer: analysts use it to judge how confident they can be in the bare-soil timing data, rather than as a standalone map.

Official description

The Bare Soil After Confidence Layer (CPBSACL) is an ancillary dataset accompanying the CPBSA layer. It quantifies the uncertainty of the bare soil period after the harvest 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. If the preceding harvest event took place in the previous calendar year, it 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 After Confidence Layer product is part of the European Union's Copernicus Land Monitoring Service. This dataset includes data from the French Overseas Territories (DOMs).
