Since its launch in August 1997, the Advanced Composition Explorer has been measuring the elemental, isotopic, and ionic charge-state composition of solar energetic particles with three new, high-resolution instruments (SEPICA, SIS, and ULEIS). These studies span the energy range from ∼20 keV/nucleon to >100 MeV/nucleon, and include elements from He to Ni (2≤Z≤28). This paper reviews early highlights of these investigations and discusses the implications for theories of the origin, acceleration, and transport of solar energetic particles. © 2000 American Institute of Physics.

    The 1991 November 15 X1.5 flare was a well observed solar event. Comprehensive data from ground-based observatories and spacecraft provide the basis for a contextual interpretation of gamma-ray spectra from the Compton Gamma Ray Observatory (CGRO). In particular, spectral, spatial, and temporal...

    Solar surface irradiance (SIS) is an essential variable in the radiation budget of the Earth. Climate data records (CDR's) of SIS are required for climate monitoring, for climate model evaluation and for solar energy applications. A 23 year long (1983-2005) continuous and validated SIS CDR based...
