What kind of off-season second crop grew in Europe (Copernicus)

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

What it measures. Flags whether an off-season secondary crop was present and sorts it into one of four types based on timing and length: short summer, long summer, short winter, or long winter. A second season is only assessed where a main season was found.

How it's made. Produced yearly from 2017 onward from satellite-detected crop timing, 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 identify cover-cropping patterns and seasonal farming choices, valuable for soil-protection policy, agricultural research, and land-management monitoring.

Official description

The Secondary Crops Type (CPSCT) dataset indicates the presence of an off-season secondary growing season and classifies it into one of four categories based on emergence date and season length: Short Summer (1), Long Summer (2), Short Winter (3), and Long Winter (4). A secondary season is only evaluated if a main season has been detected. A season shorter than 100 days is considered a short variant; otherwise it is a long variant. If the secondary crop emergence occurs before September and after the end of the main season, it is classified as a summer variant; otherwise it is a winter variant. Typically, the secondary season involves planting a cover crop. 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 Type product is part of the European Union's Copernicus Land Monitoring Service. This dataset includes data from the French Overseas Territories (DOMs).
