The Prototype Validation Exercise (PROVE) was a mini field campaign conducted at the Jornada Experimental Range in the Chihuahuan Desert, near Las Cruces, New Mexico in May 1997. The goals of PROVE were to:

• Gain experience in the collection and use of field data for EOS product validation
• Develop protocols for coordination, measurement, and data archival
• Compile a synoptic land and atmospheric data set for testing algorithms

The remote-sensing portion of PROVE involved investigators from three NASA Earth Observing System (EOS) instrument teams:

• MODIS (Moderate-Resolution Imaging Spectrometer)
• ASTER (Advanced Space-borne Thermal Emission and Reflectance Radiometer)
• MISR (Multi-Angle Imaging Spectro Radiometer)

The campaign also coincided with the AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) flight coordinated by the U.S. Department of Agriculture and with Jornada Long-Term Ecological Research projects in the same basin.
