These files contain spectra of the downwelling infrared radiation observed in the Central Tropical Pacific during the CEPEX experiment. Observations were made from the Vickers ship by FTIR (Dan Lubin data). Three different days of observations are included; many more spectra are available in the full CEPEX archive. Data consists of wavenumber in 1/cm, and radiance in W/m**2/Steradian . For March 14 the brightness temperature is also included.
