question and some correction

by slava.suslin » Mon Apr 23, 2018 11:26 am America/New_York

Good day,

If I remember right, the half-width of visible main bands of SeaWiFS and MODIS are 20 nm and 8 nm, respectively. Is it right?
In which document I could find information on the half-width bands of VIIRS/Suomi-NPP instrument?

to some correction:
in https://oceancolor.gsfc.nasa.gov/data/viirs-snpp/  written " .. VIIRS has 22 spectral bands ranging from 412 nm to 12 nm. .. " Is bold text correct?

thank you,
slava

Slava,

Most SeaWiFS bands are indeed 20nm wide, however the NIR bands are 40nm wide.  MODIS "ocean" bands are nominaly 10nm, with a few wider (412nm is 15nm).
The visible bands on VIIRS are nominally 20nm wide, but as with SeaWiFS and MODIS, one size does not fit all.  Thankfully, we have a webpage dedicated to such things :grin:

https://oceancolor.gsfc.nasa.gov/docs/rsr/rsr_tables/

...and the 12nm should be 12um - it will be updated shortly

Regards,
Sean
