Deconstructing the Steig AWS Reconstruction

(This is merely a test of a full post.. The full post can be found at

http://www.climateaudit.org/?p=5151 )

So how did Steig et al. calculate the AWS reconstruction? Since we don’t have either the satellite data or the exact path they followed using the RegEM Matlab files, we can’t say for sure how the results were obtained. However, using a little mathemagic, we can actually take the sequences apart and then we can also calculate reconstructed values for those times when the reconstructions have been replaced by the measured temperature values. I realize that there are problems with the AWS data sets, but for our purposes that is irrelevant. This analysis can easily be repeated for the updated results if and when Prof. Steig does the recalcs.

Test Post

This is for testing various techniques:

Upload of an equation from a pdf converted to a jpg

equation1

Seems to work reasonably well. Now a slightly smaller png file:

equation1a

Not bad.

Try WordPress latex:

Now redo the equation above:

SSE = \sum\limits_{k = 1}^r {\sum\limits_{t = 1}^N {\left( {Y_k \left( t \right) - \alpha _k - \beta _k X\left( t \right)} \right)^2 } }

Yes!! It works.

BSI = .465 \cdot (1.000624)^{\left( {.99 + .914T} \right)^3 }

{\rm F(x) = }\int\limits_{{\rm - }\infty }^{\rm x} {{\rm g(t)h(x - t)dt}}

Post an R script as a block quote:

download.file(“http://www.climateaudit.org/data/antarctic_mann/Data.tab”,”temp2.dat”,mode=”wb”);load(“temp2.dat”)

slopes = function(tsdat) {
star = min(time(tsdat))
slopes = rep(NA,12)
for (i in 1:12){
dat.win = window(tsdat,start=c(star,i),deltat=1)
yr = time(dat.win)
slopes[i] = ifelse(sum(!is.na(dat.win)) < 2, NA, coef(lm(dat.win~yr))[2])
}
slopes}

slope(Data$aws[,8])

all.slope = function(alldat) {
nc = ncol(alldat)
slop = matrix(NA, nrow = nc, ncol = 12)
colnames(slop) = month.abb
for (j in 1:nc) {
slop[j,]= slope(alldat[,j])}
slop}

test3 = all.slope(Data$aws[,6])

Quotes copy out wrong. This needs fixing.

New test:

Attach text document as .doc file:

collation_functions

SS = {1 \over 2}\sum\limits_{t = 1}^N {\sum\limits_{i,j = 1}^r {\mathop \delta \nolimits_i (t)\mathop \delta \nolimits_j (t)\left( {(x_i (t) - \mu _i ) - (x_j (t) - \mu _j )} \right)^2 } }

SS = \sum\limits_{t = 1}^N {\sum\limits_{k = 1}^r {\omega _k (t)\delta _k (t)\left( {x_k (t) - \tau (t) - \mu _k )} \right)^2 } }

SS = \sum\limits_{t = 1}^N {\sum\limits_{k = 1}^r {\omega _k (t)\delta _k (t)\left( {x_k (t) - \tau (t) - \mu _k (m(t))} \right)^2 } }

x_k (t) = \tau (t) + \mu _k  + \epsilon _k (t), t = 1,...,N,  k = 1,...,r
