※Cloud data screening with brightness temperature at window channel.
  • Red plots mean FTS grid observation.
  • Green plots mean FTS target observation.

Selection criteria of the TANSO-FTS monitor data

  • Select the TANSO-FTS exposure within 1 [deg.] of the CEOS site.
    (※Railroad valley: within 0.09 [deg.] of the site.)
  • Cloud screening by radiance ratio of band1 WN1(13166.556[cm^-1]) / band2 WN6(6008.327[cm^-1]).
