Tracking Long Term and Recent UAH Channel 5 Anomally Trends
In this post I present combined long term and recent trend charts of UAH Channel 5 temperature anomalies using R’s figure inside figure capability. This approach provides a better picture of global temperature trends than UAH’s day-of-y...
RClimate Script: Global Mean Sea Level Trend by Month
This RClimate Script lets users read a NetCDF file and plot the latest satellite altimetry based global mean sea level data from 1993 to the latest completed month. The trend chart shows NOAA’s Laboratory for Satellite Altimetry altimeter global mean sea level with the seasonal signal removed and inverted barometer. I will add this...
RClimate Script: Sea Surface Temperature (SST) Anomaly Trends
This RClimate Script lets users retrieve and plot the National Climatic Data Center’s monthly Sea Surface Temperature (SST) Anomaly dat series . Links to the NCDC data file and my RClimate script are included. Users can run my script with a simple R source() statement. NCDC SST Anomaly I’ve discussed the Hadley SST anomaly...
RClimate Script: NINO 3.4 SST Anomaly Trends
This RClimate Script lets users retrieve and plot the weekly NOAA NINO 3.4 SST anomaly data for 1990 to the most recent value. Links to the NOAA data file and my RClimate script are included. Users can run my script with a simple R source() statement. NINO 3.4 SST Anomaly I’ve discussed ENSO and...

RClimate Script Introduction
Would you like to be able to generate a GISS temperature anomaly trend chart on your PC with just 1 line of R script? What about downloading the R script to your PC so that you can edit the script to fit your needs? In this post I present my first RClimate Script so that...
Arctic Sea Ice Extent Trends With R
This post shows how to retrieve on-line Arctic Sea Ice Extent data from the National Snow and Ice Data Center (NSIDC), consolidate the data files, generate a csv file, summarize and plot the data and post it as a Google Docs so that interested readers can download and analyze this data series themselves. Links...
Understanding the Science of CO2’s Role in Climate Change: 3 – How Green House Gases Trap Heat
This post, the 3rd (1st here, 2nd here) in the series on Understanding the Science of CO2’s Role in Climate Change, discusses how water vapor, CO2, CH4, O3 and N2O absorb and emit the Earth’s longwave radiation, changing the Earth’s energy balance. I’ve made a 5 panel chart that shows spectra data for 5 ...
Solar Trends: Sunspot Numbers Since 1749
This is the 1st in a series of posts I will be doing on solar trends. In this post, I show how to retrieve online monthly sunspot data back to 1749, calculate average annual sunspot numbers (SSN), plot the monthly and annual average SSN as well as a lowess smooth, add the...
