What is Copernicus?
Copernicus is an EU programme aimed at developing European information services based on satellite Earth Observation andin situ (non space) data.
Copernicus is implemented by the European Commission (EC) with the support from the European Space Agency (ESA) for the Space component and the European Environment Agency (EEA) for the in situ component (https://emergency.copernicus.eu/mapping/ems/what-copernicus).
The objective of Copernicus
To monitor and forecast the state of the environment on land, sea and in the atmosphere, in order to support climate change mitigation and adaptation strategies, the efficient management of emergency situations and the improvement of the security of every citizen (https://emergency.copernicus.eu/mapping/ems/what-copernicus ).
It combines satellite observation data with data from sensor networks on the Earth’s surface to build a comprehensive picture of our planet and its environment (https://www.eea.europa.eu/about-us/who/copernicus-1 ).
The Components of Copernicus
Three components make up Copernicus: Space, Services and In Situ.
CLMS provides geographical information on land cover and its changes, land use, vegetation state, water cycle and earth surface energy variables to a broad range of users in Europe and across the World.
It supports applications in a variety of domains such as spatial and urban planning, forest management, water management, agriculture, food,...
CLMS is jointly implemented by the European Environment Agency (EEA) and the European Commission DG Joint Research Centre (JRC).
Provide satellite image mosaic in high and very high resolutions and reference datasets.
This include satellite image mosaic from contributing missions covering the territory of Europe as well as Sentinel-2 image mosaic production at global level.
It consists of reference datasets providing homogeneous pan-European coverage of some key geospatial themes, such as hydrography and elevation.
The Land Theme
The land theme is divided into four main components:
Copernicus Global Land Service – Vegetation – Products 2
Fraction of absorbed photosynthetically active radiation (FAPAR)
quantifies the fraction of the solar radiation absorbed by live leaves for the photosynthesis activity
Dry matter productivity features
represents the overall growth rate or dry biomass increase of the vegetation and is directly related to ecosystem Net Primary Productivity (NPP)
Surface soil moisture
relative water content of the top few centimeters soil,
describing how wet or dry the soil is in its topmost layer, expressed in percent saturation.
Soil water index
quantifies the moisture condition at various depths in the soil
Dry matter productivity features
Surface soil moisture
Copernicus Global Land Service – Vegetation – Products 3
Burnt area
shows burned areas and provides information about the fire season
Land cover
land cover maps represent spatial information on different types (classes) of physical coverage of the Earth's surface, e.g. forests, grasslands, croplands, lakes, wetlands
These biophysical products are useful for a wide range of thematic areas (the global crop monitoring, the food security applications; forest, water, and natural resources management; …)

Copernicus Global Land Service - Energy
The incoming solar radiation controls the life on our planet Earth.
To quantify the main responses of the continents to sun illumination, the Copernicus Global Land Service provides, in a timely manner, biophysical variables assessing the energy budget at the land surface.
Copernicus Global Land Service - Energy - Products
Land Surface Temperature
is the radiative skin temperature of the land surface, as measured in the direction of the remote sensor
Surface Albedo
quantifies the fraction of the sunlight reflected by the surface of the Earth
The directional albedo or directional-hemispherical reflectance (also called black-sky albedo)
The hemispherical albedo or bi-hemispherical reflectance (also called white-sky albedo)
Top Of Canopy Reflectances
The Top-Of-Canopy spectral reflectance quantifies the fraction of the sunlight reflected by the surface of the Earth, in a given spectral band.
Albedo
Copernicus Global Land Service - Water
To contribute to a better understanding of Earth’s water cycle, the Copernicus Global Land Service helps to monitor:
Water surface temperature and water quality of medium and large-sized lakes.
Water bodies - surface extent covered by water on a permanent basis
Water level of lakes and rivers
These products are useful for hydrological modelling as well as short- and medium-term meteorological forecasting since they control the water and heat exchanges between land and atmosphere.
Provided for the full globe in a timely manner.
Copernicus Global Land Service - Cryosphere
Snow cover has a strong influence on the Earth's radiation and energy balance.
Snow cover parameters are crucial for the prediction of water balance, streamflow and river runoff in hydrological models and water resource management.
The key cryosphere parameters monitored within the Copernicus Global Land Service:
snow coverextent,
snow water equivalent and
lake ice extent.
Snow cover extent

Ground-Based Observations for Validation (GBOV) of Copernicus Global Land Products
The GBOV service provides multiple years of high quality in-situ measurements to validate 7 core land products:
Top-of-canopy reflectances,
Surface albedo,
Fraction of Absorbed Photosynthetically Active Radiation,
Leaf Area Index,
Fraction of green Vegetation Cover,
Land Surface Temperature and
Soil Moisture

Pan-European Component
Coordinated by the European Environment Agency (EEA) and produces land cover / land use (LC/LU) information in the CORINE
Land Cover data,
High Resolution Layers,
Biophysical parameters and
European Ground Motion Service.
The CORINE Land Cover is provided for 1990, 2000, 2006, 2012, and 2018. This vector-based dataset includes 44 land cover and land use classes. The example shows the classification for 2018.
European Ground Motion Service (EGMS)
Aims to provide consistent, regular, standardised, harmonised and reliable information regarding natural and anthropogenic ground motion phenomena over Europe and across national borders.
The main objective – measuring of ground displacements, including landslides and subsidence, as well as deformation of infrastructure.
The EGMS will also provide tools for visualisation, interactive data exploration and user uptake elements for further ground investigations.
European Ground Motion Service (EGMS)
The timetable for the EEA’s implementation of the EGMS.
Aims to provide specific and more detailed information that is complementary to the information obtained through the Pan-European component.
Focus on different hotspots (areas that are prone to specific environmental challenges and problems).
It will be based on very high resolution imagery (2,5 x 2,5 m pixels) in combination with other available datasets (high and medium resolution images) over the pan-European area.
Local Component - Products
Urban Atlas
provides pan-European comparable LC/LU data covering a number of Functional Urban Areas (mayor EU city area)
Riparian Zone
addresses LC/LU in areas along rivers, i.e. the riparian zones.
Natura 2000
the aim is to map LC/LU in a selection of grassland rich sites and to assess whether those selected sites are being effectively preserved as well as, if a decline of certain grassland habitat types is being halted.
CoastalZones
LC/LU product maps from the European baseline a 10 km landwards buffer.
Imagery and Reference Data Component
Copernicus land services need both satellite images and in-situ data in order to create reliable products and services.
Satellite imagery forms the input for the creation of many information products and services.
Many in-situ data are managed and made accessible at national level.
Copernicus services and particularly CLMS relies on pan-European in-situ datasets created and/or coordinated at European level.
This in-situ data used for verification and validation of several information services in the CLMS portfolio.
