The Ocean Mixed Layer, SST, and Climate Change

By Andy May As described in my previous post, the ocean “mixed layer” is sandwiched between the very thin “skin” layer at the ocean surface and the deep ocean. The skin layer loses thermal energy (“heat”) to the atmosphere primarily through evaporation, gains thermal energy from the Sun during the day, and constantly attempts toContinue reading “The Ocean Mixed Layer, SST, and Climate Change”

Recent USHCN Final v Raw Temperature differences

By Andy May While studying the NOAA USHCN (United States Historical Climate Network) data I noticed the recent differences between the raw and final average annual temperatures were anomalous. The plots in this post are computed from the USHCN monthly averages. The most recent version of the data can be downloaded here. The data shownContinue reading “Recent USHCN Final v Raw Temperature differences”

HADCRU Power and Temperature

By Andy May Generally, it is agreed that the Earth’s top-of-atmosphere (TOA) energy budget balances to within the margin of error of the estimates (see Kiehl and Trenberth, 1997). The incoming energy, after subtracting reflected energy, is thought to be roughly 239 W/m2 which matches, within the margin of error, the outgoing energy of roughlyContinue reading “HADCRU Power and Temperature”
