Prototype Validation Exercise (PROVE) Project/Campaign Document

Summary:

The Prototype Validation Exercies (PROVE) was a mini field campaign conducted in May 1997 near Las Cruces, New Mexico, U.S.A, at the Jornada Experimental Range. Prove sought to gain experience in the collection and use of field data for EOS product validation, to develop protocols for coordination, measurement, and data- archival, and to compile a synoptic land and atmosphere data set for testing algorithms.

1. Project/Campaign Overview:

Name of Project/Campaign:

The PROtotype Validation Exercise (PROVE)

Project/Campaign Introduction:

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 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.

Project/Campaign Mission Objectives:

The goals of PROVE were to:

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

Discipline(s):

Earth Science

Geographic Region(s):

Jornada Experimental Range in the Chihuahua Desert, New Mexico, U.S.A.

Detailed Project/Campaign Description:

A diverse group of researchers from both within and without the EOS community gathered in late May 1997 at the Jornada Experimental Range near Las Cruces, New Mexico, for the Grassland Prototype Validation Exercise (PROVE). Grassland represents the first PROVE campaign (a Forest PROVE was held in August), and was the result of a joint agreement by MODIS, MISR, and ASTER, and also included participants from the USDA-Agricultural Research Service (ARS), Jornada Long Term Ecological Research Project (LTER), Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC), Boston University, and the Universities of Arizona, Colorado, Montana, Nebraska, and Oklahoma. GSFC physical scientist Jeff Privette, who helped coordinate the activity, stated, "The PROVE campaigns focus on how quickly and accurately we can measure the relevant parameters for the validation of MODIS and other AM instrument products over a range of surface conditions. During the PROVE campaigns we are prototyping remote sensing algorithms, as well as methods for collecting field data commensurate with satellite spatial resolutions, and asking how we can measure the relevant parameters on the ground to validate the planned remote sensing products.

Five data sets were compiled during this compaign:

• GOES-8 Images
• Land Cover and Leaf Area
• MQUALS Reflectance
• Surface Albedo
• Vegetation Reflectance
