Climate Indexes

1 Scope and Purpose

1.1 QBO (Quasi-Biennial Oscillation)

Original source: http://www.geo.fu-berlin.de/en/met/ag/strat/produkte/qbo/

Alternative source: http://www.cpc.ncep.noaa.gov/data/indices/

Data available at: /asl/s1/chepplew/data/atmosSci/QBO/

Sample plot: pdo_tsplot_jan2017.png

Matlab reader: /home/chepplew/myLib/matlib/load\_qbo\_index.m

Maybe filename and dirname have to be identical

1.2 ENSO & SOI (Southern Oscillation Index) Equatorial (Nino) SST

There are several options depending on Nino-regions and analysis type:

The multivariate index: https://www.esrl.noaa.gov/psd/enso/mei/index.html

Original source: http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/ensostuff/detrend.nino34.ascii.txt

Data available at: /asl/s1/chepplew/data/atmosSci/ENSO/nino12.tab, nino3.tab, nino34.tab, soi.tab, MEI.tab

1.3 Solar Cycles & Solar Flux

1.3.1 400 years Solar Flux

Original sources: Lockwood, M., Owens, M.J., Barnard, L. (2014) JGR, Centennial variations in sunspot number, open solar flux and streamer belt width.
Data available at: /asl/s1/chepplew/data/atmosSci/Solar/JGR_Lockwood_OSF3_supplementarydata.txt with matlab reader: osf_reader.m also in that directory.
And detailed solar wind variations (speed, magnetic field, proton density and proton temperature at: /asl/s1/chepplew/data/atmosSci/Solar/srep41548-s{2,3,4,5}.txt With matlab reader srep_reader.m also in that directory.
