Research Project: MONITORING ARID LAND COVER CHANGE WITH SIMULATED HYSPIRI DATA

Location: Water Management and Conservation Research

Project Number: 5347-13660-007-04
Project Type: Specific Cooperative Agreement

Start Date: Jul 01, 2012
End Date: Dec 31, 2012

Objective:
The objective of the study is to develop robust techniques that will utilize hysperspectral and multispectral visible to thermal infrared data to estimate net radiation.

Approach:
Research will investigate the benefits of incorporating hyperspectral visible-near infrared data to compensate for atmospheric effects on remote sensing image data and to utilize the modeled effects to refine estimates of atmospheric water vapor effects on thermal infrared data. The investigation will compare modeled shortwave and longwave radiation estimates for three scenarios: high resolution (15 m), moderate resolution (60 m), and coarse resolution (1km). Data for the investigation will be derived from existing airborne data collected over Jornada and Sevilleta, New Mexico from 1999 to 2003. Results from the study will be used to improve modeling of evapotranspiration.
