The CEOS Land Product Validation Subgroup

LPV Goals

To increase the quality and efficiency of global satellite product validation by developing and promoting international standards and protocols for:
  • Field sampling
  • Scaling techniques
  • Accuracy reporting
  • Data and information exchange

International Collaboration

Beyond the collaboration of LPV within the CEOS structure and related space agencies, we closely collaborate with many national and international institutions. LPV has close links to the Terrestrial Observation Panel of GCOS, to GOFC-GOLD, as well as to many in situ networks (most relevant networks are listed under the corresponding focus areas). LPV is actively seeking collaboration with ongoing validation projects such as QA4ECV and QA4EO.

LPV History 

Land Product Validation (LPV) is a subgroup of the Working Group on Calibration and Validation of CEOS.

The Land Product Validation subgroup arose out of the recognition in the late nineties that standardized approaches to global product validation were essential for wide acceptance and use of proposed global land products. Several programs at the time were aimed at global monitoring of Earth processes, many with plans to distribute higher level data products. A common approach to validation would encourage widespread use of validation data, and thus help us to move toward standardized approaches to global product validation. With the high cost of in-situ data collection, the potential benefits from international cooperation are considerable and obvious.

Requests for assistance from the original Integrated Global Observing Strategy (IGOS) pilot projects and two subsequent ad hoc meetings of the WGCV identified a clear need for improved international collaboration concerning the validation of land products derived from Earth observing satellites. A new subgroup within the WGCV was proposed to the CEOS Plenary in Stockholm at the end of 1999, receiving full support. The LPV was officially adopted as a subgroup at the WGCV-17 meeting in October of 2000.
