63-953 Climate and Satellite Data Analysis
MS Integrated Climate System Sciences
Date: 3.2.2014-7.2.2014
Place: Geom 1536c
Course objectives
The participants will learn to practically work with climate model, reanalysis, in-situ station and satellite data. Organized as a group project, the participants will further learn the principles of project management and shared software development.

Topics for group work
Coverage bias in the HadCRUT4 temperature series and its impact on recent temperature trends
Kevin Cowtan and Robert Way fill the gaps of the HadCRUT temperature data set by using satellite data. Compare their new reconstruction of surface temperature data to independent in-situ observations and reanalysis data.
Cowtand and Way (2013) methods and data are freely available:
Surface temperatures are available from the International Arctic Buoy Programme (IABP) website:
Cowtan and Way (CW2013) reconstruction
- Review methods of Cowtan and Way (2013)
- Write code to read and plot the data
- Calculate trends and variabilites
Variations in Surface Air Temperature Observations in the Arctic
- Review methods of Rigor et al. (2000)
- Write code to read and plot the gridded buoy data
- Calculate trends and variabilites
Reference:
Data intercomparison
(advanced programming skills needed)
- Write code to interpolate the different datasets in a common grid
- Compare CW2013, buoy and reanalysis data (variability and trends)
Soil moisture
- Sampling bias
