As
the total relative uncertainties in radiance calibrations of this dataset are approximately ≤ 5 % for visible and ≤ 2 % for IR cloud retrievals (where absolute uncertainties are < 10 % and < 3 % respectively).
The ISCCP calibrations are now the most complete and accurate set of calibrations available for the imaging radiometers on the weather satellites:
total relative uncertainties in the radiance calibrations are estimated to be ≲ 5 % for visible and ≲ 2 % for infrared; absolute uncertainties appear to be < 10 % and < 3 %, respectively.

This figure gives a sense of the wide
uncertainty distribution in the
total anthropogenic forcing
relative to just the GHG forcing (which also includes methane, N2O, etc) which is a prime reason the instrumental record doesn't inherently give good constraints on sensitivity.
Therefore, the
total annual and global mean radiative forcing during the LGM is likely to have been approximately — 8 W m — 2
relative to 1750, with large seasonal and geographical variations and significant
uncertainties (see Section 6.4.1).
Long - term changes may have less
uncertainty (
relative to the
total change) than short term changes.
Therefore, the
total annual and global mean radiative forcing during the LGM is likely to have been approximately — 8 W m — 2
relative to 1750, with large seasonal and geographical variations and significant
uncertainties (see Section 6.4.1).
Kohler et al. (2010; doi: 10.1016 / j.quascirev.2009.09.026) estimate
total forcing at the LGM to be — 9.5 W / m2
relative to preindustrial, with Gaussian
uncertainty having a standard deviation of between 0.9 and 1.9 W / m2.
