The graph on the left shows the blackbody radiance at 10.7 microns as a function of temperature. The sensitivity of the GOES-8 10.7 micron channel is plus or minus 0.22 radiance units. The associated temperature uncertainty increases with decreasing temperature for this as well as the other infrared channels. Here the temperature uncertainty is plus or minus 0.13 degrees at 300 Kelvins and plus or minus 0.31 degrees at 230 Kelvins. Looking at the image on the right, notice that details in both cold thunderstorm tops and the warm surface features appear noise-free.
