It provided SI-traceable detector-based spectral radiance
validation of the integrating sphere sources and illuminated diffuse plaques that are used for inter-comparison and pre-launch calibration of the SeaWiFS instrument.
and then (b) the conversion of the spectral radiance
(L) to at-sensor brightness temperature (T(k)) in Kelvin.
Solar insolation I(T) and its spectral radiance
I([lambda], T) related as follows
Emitted spectral radiance
L at wavelength [lambda] from a surface at thermodynamic temperature [T.
To convert the Digital Number (DN) ranging from 0-255 of the Landsat ETM+TIR band into spectral radiance
, the following equation was used :
Intensive phototherapy means a spectral radiance
greater than 30 mcW/[cm.
Detection of phosphorus and nitrogen deficiencies in corn using spectral radiance
AVIRIS is a unique optical sensor that delivers calibrated images of the reflected spectral radiance
in 224 contiguous spectral channels with wavelengths from 400 to 2500 nm.
1996) demonstrated that total plant N could be estimated using spectral radiance
measurements at the red (671 nm) and NIR (780 nm) wavelengths.
As shown in Figure 2, the spectral radiance
of the flare versus wavelength can have a significantly different shape than that of the tracked aircraft, which has a much lower temperature.
Fortunately, atmospheric vapors have narrow line widths that allow the modulation of the AOTF to increase the sensitivity by obtaining first and second derivatives of the spectra, as shown in Figure 7 for a laser line with 1 percent of the spectral radiance
of a glow bar in the background.

to R: [lambda] = derive trace gas 310-1,680 nm; concentrations: HCHO, [DELTA][lambda] = BrO, IO, CI[O.
A methodology for using a calibrated filter radiometer to measure and monitor the spectral radiance
of calibration sources is described.
Meanwhile, Luc Tuymans's suavely disquieting canvases at the Belgian pavilion emit a spectral radiance
, and along with the Gerhard Richters and the Richard Turtles in the Italian pavilion, constitute proof that painting need not strive, Twombly-style, for the mannerist big gesture to hold its own with installation.
Measurement error is estimated for each average spectrum, following the approach outlined in Bianchini and Palchetti (2008), by calculating the radiometric noise equivalent spectral radiance
(NESR) due to detector noise, the calibration error (Cal Err) due to the calibration uncertainty, and the standard deviation of the mean (STD).
