Since field portable spectroradiometers are often used to calibrate and validate satellite imagery, it is essential that all calibrations are traceable to accepted standards and that performance tests are carried out to confirm sufficient performance in key areas. The deployment of increased spectral resolution airborne imaging systems, such as Jet Propulsion Laboratory (JPL) Airborne Visible Infrared Imaging Spectrometer Next Generation (AVIRIS NG), require high resolution field spectroradiometers that match or exceed the performance of the airborne systems. This paper will discuss the impact of improved spectrometer resolution between 350 and 2,500 nm spectral range. This paperalsodiscusses radiance and wavelength calibration methods for field portable spectroradiometers and presents typical protocols for deriving spectroradiometer signal to noise ratio (SNR) for measurements performed using solar illumination. Finally, we will also show a new graphical user interface on a mobile device designed to aid the typical user acquire data in the field. This user interface was specifically designed to support typical field measurement protocols employed in ground based reflectance spectroscopy and radiometry.
