Extreme Rainfall Variability in Australia Patterns

Ensemble-mean 20CR fields have been used to examine Queensland rainfall variability (Klingaman et al.2013) and climate variability in southeast Australia (Ashcroft et al.2014).The 20CR fields used in this study are outgoing longwave radiation,mean sea level pressure (MSLP),zonal and meridional winds,and specific humidity.Climate Data Sets NCAR - Climate Data GuideThe CRU TS series of data sets (CRU TS = Climatic Research Unit Timeseries) contain monthly timeseries of precipitation,daily maximum and minimum temperatures,cloud cover,and other variables covering Earth's land areas for 1901-2015 (CRU TS4.0 is a recent release).Climate Data Sets NCAR - Climate Data GuideIt is only necessary to set one or two filters to narrow the results list significantly.Search by the parameters that you are most interested in,such as by variable (e.g.sea level pressure,SST,precipitation),data type (e.g.satellite,climate index,reanalysis),OR collection (e.g.Climate Data Record,obs4MIPS,diagnostic data sets).
