Field spectrometer data of calcrete from Mormon Mesa.
These values are published in our
Remote Sensing of Environment paper (in Adobe PDF) in Figure 9. That article details what these values are, and how we measured or calculated them.
The data are:
-1. The wavenumber band centers of the M21 Fourier transform spectrometer used, in inverse centimeters (cm-1).
-2. The emissivity of the diffuse aluminum target used to measure the downwelling radiance. The values given are convolved to match the field spectrometer band centers, and are on a scale of 0 to 1.
-3. The radiance measured of the diffuse target in the field. The measured data were compensated for the emissivity of the aluminum target in order simulate measuring a target with emissivity=0 (reflectance=1). The equation is given in our manuscript, and the result is the downwelling radiance, shown in Figure 9. Values given in W/cm2 sr cm-1 that have been multiplied by 106.
-4. The radiance measured of a region with near 100% coverage by calcrete. Values given in W/cm2 sr cm-1 that have been multiplied by 106.
-5. A blackbody fit to the measured calcrete radiance (see manuscript for details). Values given in W/cm2 sr cm-1 that have been multiplied by 106.
The data may be freely used, but please reference:
