August Global Temperatures

[dopeydog]

UAH are in. August = .23

Any predictions on which way gistemp goes from its +.60 July anomaly number?

My WAG for August: .62

After Rio there was Kyoto. After Kyoto, there was Copenhagen.

Copenhagen ... the legend continues.

Any predictions on which way gistemp goes from its +.66 July anomaly number?

The GISS anomaly for July was +0.6. Using the satellite baseline (1979-1998) the GISS anomaly was +0.36 which was lower than the UAH (and RSS) anomaly.

I've corrected my numbers ... can't currently find what giss data set I'd been mistakenly looking at (maybe global SSTs?). Thanks, at any rate.

Prediction?

GISS typically reports anomalies vs the 1951-80 mean (and that's what they archive in table format on their site). The .67 anomaly was against that mean.

[woodstove]

I don't think so. (The number I saw was .66, at any rate.)

The land-ocean temp data are here:

data.giss.nasa.gov/gistemp/tabledata/GLB.Ts+dSST.txt

The July number was indeed +.60

[jeroen]

Are there any anomaly maps in already?

[jimcripwell]

GISStemp is in for August; 0.51. I think 6th warmest. YTD 0.53 I think 7th warmest. July was 0.63. Not much sign that, even according to Jim Hansen, global temperatures are still rising.

GISS data for first 8 months each year since 1998

1998 0.64*
1999 0.33
2000 0.37
2001 0.45
2002 0.60*
2003 0.51
2004 0.45
2005 0.62*
2006 0.50
2007 0.61*
2008 0.39
2009 0.53

Fifth warmest since 1998

RSS is 0.270, down from July's 0.392. This is despite a moderate El Nino. If this is an El Nino, I hate to think what a La Nina would look like. January 2008, anybody?

A couple of points here:

1. If an 'official' El Nino does develop it's likely to be fairly weak.
2. In September 1997 the 1997-98 El Nino was ~3 months old (the current one is ~2months old). The Aug '97 satellite anomalies were as follows

UAH +0.10
RSS +0.20

i.e. there is often a significant lag.

Lets not stare blind on el nino's. Next month can go up or down. I am really interestet in the anamoly maps. Last month was up because of the antartic with not much weatherstations. I wonder wat isolated part off the world was hot this month

These are GISS anomaly maps

1. Using the 1951-1980 baseline

2. Using the 1979-1998 (satellite) baseline

data.giss.nasa.gov/cgi-bin/gistemp/do_nmap.py?year_last=2009&month_last=08&sat=4&sst=1&type=anoms&mean_gen=08&year1=2009&year2=2009&base1=1979&base2=1998&radius=1200&pol=reg

GISS has updated their August update with changes all the way back to 1882 ;D If you're following their data, August should be 0.52, not 0.51. Clear your cache and re-download if necessary.

I assume the changes were to...as always...increase the linearity of the data.
