under contract for NASA has performed flawlessly in its first year on orbit as the most accurately calibrated radiometer
in the twelve-satellite GPM constellation.
In building these capabilities, the scientists at the Optical Technology Division of NIST (OTD) became experts by the late 1990s in designing and building cryogenic radiometers
The Simultaneous View Correlation Radiometer
(SVCR) was designed specifically for the realSens[TM] instrument to detect the presence of leaked natural gas near the Earth's surface from an airborne platform.
This, of course, assumes that the spectral distribution of the lamp is reasonably stable, and the ratio of energy in the radiachromic response band is constant with respect to the radiometer
band of interest for correlation.
Canopy reflectance was calculated for each waveband based on an intercalibration of the nadir-viewing and the up-looking radiometers
with respect to a calibrated barium sulfate panel.
With more than 200 microwave radiometers
in operation worldwide, the company is the world leader in ground based microwave radiometer
product innovation and sales.
Spyak, A 400 nm to 2500 nm absolute spectral radiance comparison using filter radiometers
, Metrologia 35 (4), 563-568 (1998).
Differences in detectors, filters, construction, and principles of operation result in the fact that different narrow-band radiometers
give different results when measuring broad-band sources.
EIT's Palm Probe is the newest member of EIT Instrument Market's family of radiometers
The thermal imagers and the radiometers
that Pretory will distribute and provide services with are the aircraft based systems of these same technologies which include the MAVR-S multi-spectral high resolution apparatus, the TAVR-S high resolution multi-spectral apparatus, and the multi-spectral radiometer
Myneni of Boston University and his colleagues discovered the enhanced plant growth by analyzing data from radiometers
flying on weather satellites.
It offers a line of infrared temperature measurement instruments, thermal imaging systems, radiometers
, spectrometers, and blackbody sources for the calibration of infrared thermometers.
