**Desirable measurements at ''Anchor Stations''**/

Continuously:
Atmospheric transmittance (spectral)
Net radiation flux; preferable all four radiation fluxes plus in addition independently the net flux
Bowen ratio (including the measurements of air temperature and humidity at two levels)
Soil heat fluxes and temperatures at least at four levels
Precipitation
Soil moisture at three levels: near surface, intermediate, root layer
Effective radiation temperature of the surface
Ground water (piezometric) level

Occasionally (especially under extreme situations):
Sensible and latent heat fluxes separately by advanced methods (e.g. eddy correlation)
Vegetation parameters such as leaf area index (LAI), fractional coverage, biomass area density, stem flow, stomata resistance, vegetation height, vegetation structure, leaf orientation & size
Land use at and around the station

From time to time at longer intervals:
Soil quality
Radiometric characteristics (e.g. reflectance function)

At the central data bank the following derived quantities have to be computed from the measured values:

Wavelength dependent optical depth and vertical distribution of water vapour mass as needed for the correction of satellite data. The goal must be to derive a climatology of aerosol optical properties for the region. If reliable algorithms become available to compute atmospheric corrections from measurements made in space, this network serves the validation of these algorithms and the quality control of atmospheric corrections. This task can be supported by measurements made in the areas of the anchor stations by aircraft in order to obtain a better areal coverage.

Daily and monthly values of all flux components (radiation, sensible heat, latent heat, soil heat flux respectively heat storage in the soil).

Soil moisture as the difference between precipitation, latent heat flux, and storage.

Ratio of directional reflectance to albedo (according to models parametrized with respect to the measured quantities that are still to be developed).

Surface conductance.
