      abstract     = {Limb sounding instruments play an important role in the
                      monitoring of climate trends, as they provide a good
                      vertical resolution. Traceability to the International
                      System of Units (SI) via onboard reference or transfer
                      standards is needed to compare trend estimates from multiple
                      instruments. This study investigates the required
                      uncertainty of these radiation standards to properly resolve
                      decadal trends of climate-relevant trace species like ozone,
                      water vapor, and temperature distribution for the Gimballed
                      Limb Observer for Radiance Imaging of the Atmosphere
                      (GLORIA). Temperature nonuniformities of the onboard
                      reference blackbodies, used for radiometric calibration,
                      have an impact on the calibration uncertainty. The
                      propagation of these nonuniformities through the retrieval
                      is analyzed. A threshold for the maximum tolerable
                      uncertainty of the blackbody temperature is derived, so that
                      climate trends can be significantly identified with GLORIA.},
