The Blackboard

RSS posted their observed temperature anomalies for the lower troposphere yesterday. The October anomaly of 0.282C fell relative the September anomaly of 0.474C. The drop of nearly 0.2C sounds large– but, “hey!” that’s weather in our lower troposphere! (The UAH October anomaly of 0.284 C was lower than their November anomaly of [...]

UAH temperature anomalies were officially posted yesterday. I thought you all might like to see a graph of temperature anomalies with uncertainty intervals. I included a trend of 2C/century for references:
As you can see:

The trends for both UAH and RSS are negative since 2001 with RSS having the larger negative trend.
If [...]

Here’s the skinny on recent RSS anomalies, in graphical form:
Temperature anomalies in pictures:

April’s RSS of 0.202 C dropped to a May RSS of 0.090C.
For those who prefer to notice anomalies rose, the May 2008 RSS of -0.078C rose to a May 2009 RSS of 0.090C.
For those wondering how UAH and [...]

RSS posted their anomaly: The Lower Troposphere warmed relative to the temperature in March 2009 and April 2008. I’ve created a very cluttered graph illustrating many things about RSS below:
As you can see:

The observed temperature from April, 2009, which is circled in red, and enclosed in a black triangle is up from March [...]

As most of you are no doubt aware, both RSS and UAH reported temperatures for the troposphere during my absence: Both dropped relative to February.
Needless to say, Anthony and Roy both scooped me on these (as did David.) But I won’t let that stop me from posting some images.
Below, I plotted RSS [...]

The torrential March rains in the Chicago area immersed my Comcast connection. When I got back on line, I discovered my readers had alerted me to the odd divergence in RSS and UAH temperatures. Here’s the scoop:

UAH says the temperature anomaly for the lower troposhpere rose from 0.304 C in Jan 2009 to 0.35 [...]

The RSS Anomaly has been reported here. Though we have been freezing our rears in Chicago, the global temperature anomaly rose relative to December. Since much of the focus for tropospheric temperatures involves values since the satellites began, I computed the trend since 1979. (The graph only displays since 1980.)
Interestingly, January’s anomaly [...]

The RSS anomaly for December has been posted.

Dec 2008: 0.174
Nov 2008: 0.216
Dec 2007: 0.096

So it’s quite a bit warmer than Dec. 2007, but colder than last month. It’s on the low side relative to temperatures since Jan 2001 (which I use as my start date for comparing AR4 projections to observations.)
Here’s a [...]

The RSS November anomaly is 0.216 C. This is higher than 0.131 C for Nov. 2007 and 0.181 C for October 2008.
I may have scooped the others… I guess we’ll see.
