If the Flight of the Concords taught me anything, it's that you can't trust Australians. This morning I was poking around the DataMarket site, when I noticed something suspicious about Australian sheep production: I decided to investigate further: ju...
In this post I set both UAH 5.4 and RSS 3.3 global temperature anomaly series to a common baseline period (1981-2010) to compare them. Since both the UAH 5.4 and RSS 3.3 series are satellite based , they exhibit striking … Continue reading →
In this post I set both UAH and GISS global temperature anomaly series to a common baseline period (1981-2010) and compare them. Even though the UAH series is satellite based and GISS series is station based, the series exhibit striking … Conti...
In this post I show one simple and 2 multiple regression models to assess the role of time, El Nino – La Nina SSTA and volcanic activity (SATO) on UAH global temperature anomaly trends. The 3rd model provides a reasonable … Continue rea...
In this post I compare GISS LOTAs during 5 El Nino – La Nina cycles (2010, 1998, 19883, 1973 and 1970). El Nino – La Nina Cycles In a previous post I showed the Nino 34 SSTA cycles for 2010, … Continue reading →
In this post, I use a quadratic regression model to forecast the September, 2011 Arctic Sea Ice Extent. The model was developed with 1980 – 2010 data. Links to the R script, source data and how-to article on polynomial regression … ...
In a previous post, I showed the Lower Stratospheric Temperature Anomaly (TLS) Trends (link). A reader submitted the following comment: “The lower stratosphere temperature profile is essentially flat from ca. 1995 to the present. This approxima...
In this post I review the temperature structure of the atmosphere and lower stratosphere temperature (TLS) anomaly trends. Temperature Structure in the Atmosphere In post 1 of this series, I developed this RClimate chart of temperature soundings whic...
I am pleased to announce my CTS.csv file which includes 18 climate monthly time series in one easy to access csv file. This is part of my goal of having a user friendly way for do-it-yourself citizen climate scientists to … Continue reading ...
This post shows how to use RClimate.txt to retrieve a climate time series and write a csv file in 5 lines of R script. One of my readers, Robert, wants to be able to download climate time series data and … Continue reading →
