ACRIMII  

Definition

  • The second Active Cavity Radiometer Irradiance Monitor (ACRIM) satellite solar monitoring experiment (ACRIM II) has been providing total solar irradiance observations since its launch as part of the Upper Atmospheric Research Satellite (UARS) in late 1991. The UARS is a three-axis stabilized, Earth-oriented spacecraft with an orbit at inclination of 57 degrees and altitude 585 km. The UARS orbit provides about 60 minutes of sunlight in each orbit of which about 35 minutes are available for solar viewing. During this period the Solar/Stellar Pointing Platform points the instrument to the center of the Sun. For more information link to: "http://www.ngdc.noaa.gov/stp/SOLAR/IRRADIANCE/uars.html" (en)
