Objectives

   * Establish linkages between site data archives to facilitate improved product access and knowledge assessments of the long-term stability and interoperability to address the challenges of the Terrestrial Carbon Observation (TCO) theme.

* Ramp-up validation efforts, leveraging off of the infrastructure and protocols developed through existing site activities,

   * Address science questions suitable for combined field and multi-resolution data.

   * Enable ready collaboration between validation investigators and existing science networks and programs.

   *  Facilitate validation activities directed at better product knowledge and assessment of the products’ stability and interoperability.
