Length of Europe's off-season second-crop seasons (Copernicus)

CLMS VLCC Secondary Crops Duration (CPSCD) Europe 10m yearly V1
biosphere ESA ESA Copernicus active
In plain English

What it measures. Measures how many days a secondary, off-season crop grew in each field, ranging from about 40 days up to a full year.

How it's made. Produced yearly from 2017 onward from satellite vegetation data, by the EU's Copernicus Land Monitoring Service at 10-metre resolution across Europe's 38 countries, including French overseas territories.

How & where you'd use it. Helps monitor cover-cropping and off-season farming over time, supporting policies that aim to prevent soil degradation and track changing cropping practices.

Official description

The Secondary Crops Duration (CPSCD) dataset provides information on the length of the secondary crop growing season, expressed in days (range: 40–366). The secondary season layers offer valuable information for assessing policy implementation to prevent soil degradation and for monitoring cropping changes during off-season periods over time at regional and national level. 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 Secondary Crops Duration product is part of the European Union's Copernicus Land Monitoring Service. This dataset includes data from the French Overseas Territories (DOMs).
