MJO TimeseriesPSD is creating a set of MJO timeseries that quantify current and historic MJO activity.
The links and descriptions are below as well as links to some other MJO timeseries created at other institutions. A description of the format is available.
Daily Time series from 1979 to 2013
The OLR MJO Index
|Projection of 20-96 day filtered OLR, including all eastward and westward wave numbers onto the daily spatial EOF patterns of 30-96 day eastward filtered OLR.||OMI values|
The Filtered OLR MJO index.
|Univariate EOF of normalized 20-96 day filtered OLR averaged from 15S-15N.||FMO values|
The Real-time Filtered OLR MJO index.
|Real time OMI derived from OLR anomaly data with the previous 40 day mean removed and a 9 day running mean applied, projected onto the spatial EOF patterns of FMO.||RFMO values|
Kiladis G.N., J. Dias, K.H. Straub, M.C Wheeler, S.N. Tulich, K. Kikuch, K.M. Weickmann, M.J. Ventrice. A comparison of OLR and circulation based indices for tracking the MJO. Submitted to Monthly Weather Review, 2013.An animation of the daily EOF's is available (realtime player format).
