N1 - Funding Information:
This campaign benefited greatly from the competent staff at the ARS Jornada Experimental Range, who were called upon numerous times to solve field problems. The MISR team, particularly Mark Helmlinger, also helped many teams with various problems. We sincerely thank them. We also thank Dan Baldwin and Bill Emery (CU/CCAR), who provided the AVHRR data; Marc Leroy (CNES/CESBIO), who provided the POLDER data; the Landsat Science Project Office, which provided the Landsat imagery; and J.P. Anderson, who provided the meteorological data. JLP thanks NASA's Terrestrial Ecology Program (D. Wickland, Manager), Nader Abuhassan, and the AERONET team for their support. Finally, we are indebted to Laura Rocchio, Barbara Nolen, and Kris Havstad for their support and efforts. Barbara also provided the land-cover map in Fig. 2 . This project was largely funded by the MODLAND, MISR, and ASTER teams.

N2 - The Earth Observing System (EOS) instrument teams must validate the operational products they produce from the Terra spacecraft data. As a pilot for future validation activities, four EOS teams (MODIS, MISR, ASTER, and Landsat-7) and community experts conducted an goals of the Prototype Validation Exercise (PROVE) included (1) gaining experience in the collection and use of field data for EOS product validation; (2) developing coordination, measurement, and data-archiving protocols; and (3) compiling a synoptic land and atmospheric data set for testing algorithms. PROVE was held at the USDA-Agricultural Research Service's (ARS) Jornada Experimental Range, an expansive desert plateau hosting a complex mosaic of grasses and shrubs. Most macroscopic variables affecting the radiation environment were measured with ground, air-borne (including A VIRIS and laser altimeter), and space-borne sensors (including A VHRR, Landsat TM, SPOT, POLDER, and GOES). The Oak Ridge Distributed Active Archive Center (DAAC) then used campaign, data sets to prototype Mercury, its Internet-based data harvesting and distribution system. This article provides general information about PROVE and assesses the progress made toward the campaign goals. Primary successes included the rapid campaign formulation and execution, measurement protocol development, and the significant collection, reduction, and sharing of data among participants. However, the PROVE data were used primarily for arid-land research and model validation rather than for validating satellite products, and the data were slow to reach the DAAC and hence public domain. The lessons learned included: (1) validation campaigns can be rapidly organized and implemented if there are focused objectives and on-site facilities and expertise; (2) data needs., organization, storage, and access issues must be addressed at the onset of campaign planning; and (3) the end-to-end data collection, release, and publication environment may need to be readdressed by program managers, funding agencies, and journal editors if rapid and comprehensive validation of operational satellite products is to occur.
