Venµs spectral bands
Update: Solar irradiance values have slightly changed (and significantly for band B2)
Here is a text file that provides VENµS spectral responses. The first column provides the wavelength, in µm, and the successive columns provide the spectral response of each band, from B1 to B12.
Solar Irradiance
The following table provides the Equivalent wavelength of each Venµs channel, and the equivalent irradiance, if you want to convert Venµs reflectances into radiances.
| Spectral band | Equivalent Solar irradiance (W/m2/µm) | Equivalent wavelength(nm) |
| B1 | 1661.634 | 423.9 |
| B2 | 1954.005 | 446.9 |
| B3 | 1990.678 | 491.9 |
| B4 | 1830.509 | 555.0 |
| B5 | 1669.217 | 619.7 |
| B6 | 1670.402 | 619.5 |
| B7 | 1510.949 | 666.2 |
| B8 | 1428.368 | 702.0 |
| B9 | 1290.557 | 741.1 |
| B10 | 1163.151 | 782.2 |
| B11 | 965.547 | 861.1 |
| B12 | 879.865 | 908.7 |
Thank You very much!
Hi,
Just a question: in the Figure, B4 and B5 appear to cover approximately the same spectral range, while in the Table it is B5 and B6 that appear to cover the same range?
I guess there is a mistake about B5 somewhere…
Exact, and thanks for this comment ! You should trust the table and not the figure. Now, I need to find where the bugged code that produced the figure was. I guess the issue is that the band numbering starts at 0…
