24. AUSTRALIAN SITES FOR THE VALIDATION OF SATELLITE
RETRIEVALS OF THE RADIATIVE PROPERTIES OF LAND
SURFACES

6.
CONCLUSION AND FUTURE
This paper has outlined the goals of the CIGSN network, described its
first two sites, and presented some preliminary results from a campaign to
validate the comparison of top-of-atmosphere radiances measured at the sites
by the ATSR-2 with surface measurements. Similar campaigns will be
planned to validate the data and products of several satellite sensors to be
launched over the next few years. A third CIGSN site is planned for tropical
Australia to extend the validation activities to conditions of high humidity.
