Earlier studies of spatial variability in sea surface temperature (SST) using ship-based radiometric data suggested that variability at scales smaller than 1 km is significant and affects the perceived uncertainty of satellite-derived SSTs. Here, we

A Microbolometer Airborne Calibrated Infrared Radiometer: The Ball Experimental Sea Surface Temperature (BESST) Radiometer

Autor: M. A. Izaguirre, William S. Good, William D. Tandy, William J. Emery, Peter J. Minnett

Publikováno v: IEEE Transactions on Geoscience and Remote Sensing. 52:7775-7781

A calibrated radiometer has been developed to enable the collection of accurate infrared measurements of sea surface temperature (SST) from unmanned aerial vehicles (UAVs). A key feature of this instrument is that in situ calibration is achieved with

Comparing the theoretical performances of 1.65- and 3.3-μm differential absorption lidar systems used for airborne remote sensing of natural gas leaks

Autor: Ashwin Yerasi, R. A. Barton-Grimley, William D. Tandy, William J. Emery

Publikováno v: Journal of Applied Remote Sensing. 12:1

Airborne remote sensing approaches to natural gas leak detection have recently become a viable alternative to traditional in situ surveillance methods. However, there have been few formal studies addressing the advantages and disadvantages of the var

Analysis of the impact of wavelength separation on reflectivity error for differential absorption lidar using the ASTER spectral library

Autor: Jarett Levi Bartholomew, Ashwin Yerasi, William D. Tandy, William J. Emery

Publikováno v: Journal of Applied Remote Sensing. 11:1

An investigation of the sensitivity of a gas-detecting, airborne differential absorption lidar to the wavelength-based reflectivity variations of the ground was made using the Jet Propulsion Laboratory’s (JPL) reflectance library. The JPL library c

MOIRE: Membrane Material Property Characterizations, Testing and Lessons Learned

Autor: Jeanette L. Domber, Paul D. Atcheson, Jeff Kommers, Brandon Farmer, Tracy Copp, William D. Tandy

Publikováno v: Spacecraft Structures Conference.

The Membrane Optical Imager (for) Real-time Exploitation (MOIRE) programs’ primary optics are constructed using a membrane material. Using a membrane enables the goal of the MOIRE program to launch large, greater than 10m aperture, optics while sim
