Reliability scores for the fallow-land duration map (Copernicus)

CLMS VLCC Fallow Land Duration Confidence Layer (CPFLDCL) Europe 10m yearly V1
biosphere ESA ESA Copernicus active
In plain English

What it measures. A companion quality layer that estimates, in days, how uncertain the measured length of fallow time is for each field over a five-year window. Fields that lay fallow for entire calendar years carry a special flag instead of a value.

How it's made. Covers 2017 to 2021, produced by the EU's Copernicus Land Monitoring Service as a 10-metre grid over Europe's 38-country reference area, including French overseas territories.

How & where you'd use it. A technical support file that lets analysts gauge how much confidence to place in the fallow-land duration figures before using them in agricultural or policy analysis.

Official description

The Fallow Land Duration Confidence Layer (CPFLDCL) is an ancillary dataset accompanying the CPFLD layer. It quantifies the uncertainty of the total fallow land duration over the five-year reference period, expressed in days (range: 1–200). The uncertainty is derived from the uncertainty of the harvest events that define the fallow land duration. If the fallow land duration over the years always entails the full calendar year, it is not possible to calculate a confidence value and a dedicated flag is assigned. This dataset covers the period 2017–2021 in 10-metre rasters (fully conformant with the EEA reference grid) in 100 × 100 km tiles covering the EEA-38 countries. The HRL Fallow Land Duration Confidence Layer product is part of the European Union's Copernicus Land Monitoring Service. This dataset includes data from the French Overseas Territories (DOMs).
