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 [...]

Dr. Roy reports an August anomaly of +0.231. This is lower than July, and lower than the Channel 5 AMSU reading for August. I bet the average AMSU reading on the day the poll closed which was too high. (My ’sockpuppet Lucia’ also bet high, as did “test person”. Yes. Those are [...]

I know some of you love to hate GISSTemp. But, fair is fair, El Niño is now showing in the satellites data too. Here’s Channel 5 AMSU:
Below, I subtracted the 20 year mean and show daily channel 5 anomalies:

UAH’s temperature anomaly sagged to 0.001C in June, drooping further relative to the 0.04C May value. Despite VG’s encouragement, the tempeature anomaly did not break through the zero barrier. Here’s a plot showing longer and shorter term trends, and highlighting June temperature readings.
My quick scan indicates VG may have posted the closest specific [...]

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 [...]

Troposphere temps up or down? Yesterday, RSS said up; today, UAH says down. Here are the temperature anomalies since UAH began operation:

UAH for March was 0.208 C; April’s 0.091 anomaly is C . That’s quite a drop! (In contrast, RSS rose 0.04C.)
UAH for April 2008 was 0.015 C; April 2009 was 0.244C. [...]

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 [...]

UAH reports the temperature anomaly rose from +0.116C in October to +0.254 C November. Below, I have plotted monthly data for both satellites since Jan 2001 rebaselined to the average for the period. The trend is just the OLS fit to the average of the two monthly anomalies reported by the two [...]
