Contains the spectral curves for the atmospheric conditions called :name.
The width of this table is the same as that of
/SpectralSamples and columns in this table correspond to
wavelengths stored in that table. The curves for solar declination sample in
column i of /SolarDeclinationSamples can be found
according to the following table.
| Curve | Row | Units |
|---|---|---|
Ground-reaching solar irradiance |
|
W / (cm^2 micron) |
Path radiance per meter |
|
W / (cm^2 sr m micron) |
Path extinction per meter |
|
1 / m |
Hemispherical sky irradiance |
|
W / (cm^2 micron) |
