Data Set Abstract |
This dataset contains calibrated, 1.05- to 4.8-micron spectra of
Earth acquired by the High Resolution Infrared Spectrometer
(HRII) during the EPOCh and Cruise 2 phases of the EPOXI mission.
Five sets of observations were acquired on 18-19 March, 28-29 May
and 04-05 June 2008 and on 27-28 March and 04-05 October 2009 to
characterize Earth as an analog for extrasolar planets. Each
observing period lasted approximately 24 hours, and spectra were
acquired twice every 2 hours. During the observing period in May
2008, the Moon transited across Earth as seen from the
spacecraft. HRII spectra were not acquired during the first
attempt of an Earth south polar observation on 27-28 September
2009 because fault protection turned that instrument off; the
full sequence was successfully rerun on 04-05 October 2009.
Version 2 corrects an error in the IR absolute calibration that
previously inflated all spectra by a factor of 2. |
