A workshop on the use of JDSP/ESE tools for sustainability applications was conducted at ASU on January 27, 2012. The main speaker was SenSIP Collaborator Prof. Linda Hinnov from Johns Hopkins University. Hands-on sessions included analysis of environmental data using the JDSP tool.
Organizers:
Prof. Linda Hinnov, Johns Hopkins University
Prof. Andreas Spanias, Arizona State University
Karthikeyan Ramamurthy, Arizona State University
Description:
Analysis of Earth system signals, important to the assessment of global climate change, will be conducted with free online Java-DSP/ESE tools. An introduction to signal processing is followed by a tutorial that examines modern records of global temperature, atmospheric carbon dioxide and sea level. The aim is to understand interactions between CO2 climate change and sea level. Several modern climate change datasets will be analyzed and compared.
Workshop Outline:
1) Learn basic signal processing with the online J-DSP/ESE Laboratory
– Signal and noise
– Trend estimation
– Spectral analysis
– Filtering; differencing
– Correlation; coherency
2)Analyze instrumental time series data of critical climate components/drivers
– Global temperature records (GISS, NCDC, HadCrut, Berkeley)
– Atmospheric carbon dioxide/fossil fuel emissions records
– Global sea level records (tidal gauge v. satellite)
3) Address fundamental questions such as
– What are the variations (frequencies) in these records?
– Do fossil fuel emissions explain the rise in pCO2?
– How is pCO2 correlated with global temperature?
– Does global temperature correlate with sea level?
– Forecasting temperature and sea level change for the next 10, 50, 100 years?
The event is co-sponsored by NSF (Award No. 0817596) and the SenSIP Center, Arizona State University.
