1. SCIAMACHY - The Need for Atmospheric Research from Space

Fig. 1-1
Atmospheric science spaceborne instruments and missions since 1970 with relevance for SCIAMACHY. The list of missions is not intended to be complete but to illustrate the progress in spaceborne instrumentation for atmospheric composition monitoring. (Courtesy: DLR-IMF)

Fig. 1-5
Global, annual mean radiative forcings (W/m2) due to a number of agents for the period from pre-industrial (1750) to present (2005). The height of each box denotes a central or best estimate value. The vertical bars visualise an estimate of the uncertainty range, for the most part guided by the spread in the published values of the forcing. A 'level of scientific understanding' index is associated to each forcing, with high, medium and low levels, respectively. (Courtesy: adapted from IPCC 2007)
