The following are ‘living documents’ and will be updated throughout the FRM4VEG program of work.

The ‘FRM Protocols and Procedures’ documents are manuals for calibrating field instrumentation, conducting field measurements in relation to both campaign and permanent field acquisitions, as well as describing how those measurements should be treated for upscaling to satellite pixels.

The ‘Validation Methodology’ documents provide an overview of the methodology used to validate satellite products over vegetated FRM-compliant field sites.

The ‘Technical Handbooks’ should be used as a guide to operate the in situ measurement instruments. Their purpose is to provide an instrument technical description, together with information about maintenance and calibration history, pre-deployment uncertainties estimates, and steps required to achieve FRM status.
