Global satellite observations of land surface properties offer temporally and spatially explicit information essential to understanding landatmosphere interactions and their impacts on the Earth system and climate. The value of these data for science applications and research is dependent upon the known accuracy of the data. The Committee on Earth Observation Satellites (CEOS), recognized as the space arm of the Group on Earth Observations (GEO), plays a key role in coordinating the land product validation process. The Land Product Validation (LPV) subgroup of the CEOS Working Group on Calibration and Validation (WGCV) aims to address the challenges associated with global land product validation. The mission of the LPV subgroup is to foster and coordinate international validation activities for satellitederived land products, to develop international validation protocols for land products, promote data sharing, and to ensure that data and results are available to the user community. Since the establishment of the subgroup in 2000, significant progress has been made toward the validation of several land products, including land cover, active fire, LAI, and albedo. Additional products such as burned area, soil moisture, vegetation phenology, and land surface temperature now require similar validation efforts. The recent emphasis on the independent and systematic evaluation and validation of terrestrial essential climate variables (ECVs) has prompted the establishment of 8 focus groups within LPV (Land Cover, Biophysical, Surface Radiation, Fire, Soil Moisture, Land Surface Temperature, Phenology, and Snow Cover), each led by two internationally independent community members. This structure, implemented in 2009, allows for a stronger working group with a closer proximity to the corresponding land community. This working group enhances feedback and collaborative efforts in relation to global independent validation and product intercomparison, and associated ground network and measurement databases. The LPV subgroup has strong collaborative links with the GOFC-GOLD land and fire implementation teams, through which Forest Carbon Tracking, UN-REDD, and the Global Land Cover validation exercise activities are being promoted.
