These two graphs show the response curves for 3.9 and 10.7 micron channels. The radiance increases more rapidly with increasing temperature for the 3.9 micron channel than for the 10.7 micron channel. Thus, the sensitivity of the GOES-8 3.9 micron channel is plus or minus 0.0086 radiance units. Notice that as temperature decreases temperature uncertainty dramatically increases. The uncertainty is 0.23 degrees at 300 K and 5.9 degrees at 230 K. The result of this uncertainty is most evident as noise in pixels with cold cloud tops, which is not the case for the 10.7 micron channel.
