Animated Images of Arctic Sea Ice Extent Decline
R Script to Build Animation of Arctic Sea Ice Extent – Update 9/3/12
In my previous post I showed an animation of Arctic Sea Ice Extent from the 1980′s through August, 2012 (link). In this post, I show how to build this Arctic Sea ice Extent animated chart. Source Data The Arctic Ice … Continue reading →
Comparison of UAH and RSS Time Series with Common Baseline
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 →
Comparison of UAH and GISS Time Series with Common Baseline
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 … Continue reading →
UAH Temperature Anomalies Following Predictable Pattern
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 reading →
Comparison of GISS LOTAs During 5 El Nino – La Nina Cycles
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 →
September 2011 Arctic Sea Ice Extent Forecast
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 … Continue reading →
Assessing Climate Trends: Eyeball versus 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 approximately mirrors the temperature trend … Continue reading →
Atmospheric Temperature Structure : 2 – Stratospheric Cooling
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 which I update … Continue reading →
Climate Time Series In a Single CSV File: Update 1
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 →
