Level 3A does not remove flares, so it is useful for short-term flare studies. Users that wish to publish the results derived from TIMED data should normally offer co-authorship to the PI or his/her designated team member. Co-authorship may be declined. Appropriate acknowledgement to institutions, personnel, and funding agencies should be given. spase://CNES/Person/T.Woods PrincipalInvestigator Dataset description http://lasp.colorado.edu/data/timed_see/level3a/README_SEE_L3A_012.TXT timed-see-flux PartOf EUV / X ray spase://SMWG/Repository/CNES/CDPP-AMDA Online Open AMDA at CDPP http://amda.cdpp.eu Text AMDA is a science analysis system provided by the Centre de Donnees de la Physique des Plasmas (CDPP) supported by CNRS, CNES, Observatoire de Paris and Universite Paul Sabatier, Toulouse http://lasp.colorado.edu/data level3a spase://CNES/Instrument/CDPP-AMDA/TIMED/SEE Irradiance 1997-09-02T00:00:12Z 2019-03-02T23:59:47Z PT90M Earth.NearSurface.Ionosphere SEE Level 3A data files contain observation averaged solar irradiance spectra in 1 nm intervals extracted from the EGS Level 2A and XPS Level 2A data products. Shortward of 27 nm, a solar model is scaled to match the XPS broadband data. SEE Level 3A data files also contain 38 emission lines extracted from EGS Level 2A spectra, and the XPS Level 2A diode irradiances. For normal operations, SEE observes the Sun for about 3 minutes every orbit (97 minutes), which usually gives 14-15 measurements per day. The SEE Level 3A data are time averaged over each observation, after applying corrections for atmospheric absorption, degradation, and to 1-AU (no flare removal). A suborbital (sounding rocket) payload is flown approximately once a year for TIMED SEE absolute calibrations. The first SEE suborbital calibration flight was on Feb. 8, 2002, the second was on Aug. 12, 2003, the third was on Oct. 15, 2004, the fourth was on Oct. 28, 2006, and the final SEE calibration flight was on Apr. 14, 2008. There are also three SDO EVE calibration flights used for checking SEE degradation trends - May 3, 2010, Mar. 23, 2011, June 23, 2012, Oct 21, 2013, and June 1, 2016. flux : spectra timed_sp_high Merged median solar irradiance for XPS and EGS flux at 1nm bins W/m**2/nm Spectrogram -1 flux : lines timed_ln_high Integrated median spectral line irradiance W/m**2/nm TimeSeries -1
