D. Crommelynck et al., PRELIMINARY-RESULTS FROM THE SOVA EXPERIMENT ON BOARD THE EUROPEAN RETRIEVABLE CARRIER (EURECA), Metrologia, 30(4), 1993, pp. 375-379
The experiment SOVA (SOlar VAriability) on board EURECA (EUropean REtr
ievable CArrier) contains two types of radiometers sunphotometers for
measuring the total and spectral irradiance at five wavelengths betwee
n 335 nm and 862 nm. Besides the direct observation of variations of t
he solar irradiance, these measurements will also be used for the obse
rvation of solar oscillations. Preliminary results are presented from
the observations of total and spectral irradiance during the first fiv
e months of the mission (August to December 1992).
