Material to Calculate Jet Indices (Code, Input Data and Output Data)

This dataset accompanies the paper "Atlantic Jet and Recurrent Weather Patterns Drove Past Hydroclimate Extremes in Europe" by Stefan Brönnimann, Jörg Franke, Veronika Valler, Ralf Hand, Eric Samakinwa,,3 Elin Lundstad, Angela-Maria Burgdorf, Laura Lipfert, Lucas Pfister, Noemi Imfeld, and Marco RohrerThe zip-File contains the R code for calculating the jet indices described in the paper as well as the calculated indices. It contains the filsCode: jet_Indices.RInput: pattern_strength.txt, pattern_tilt.txt, pattern_latitude.txt (files with the patterns from which jet indices are calculated with linear regression, rows = longitudes from 30° W to 40°E, columns from 75 to 35° N (north to south)latitude_weights.txt: latitude weights for the regression, rows = longitudes from 30° W to 40°E, columns from 75 to 35° N (north to south)z500.ltm.RData long term mean Z500 for calculating anomalies, dimensions are longitude (30° W to 40°E), latitude (75 to 35° N), and calendar month (Jan-Dec)ModE-RA_m041_geopoth_50000_abs_1420-2009.nc is a sample input file from ModE-RAIndices:ModE-RAclim-strength File with monthly indices of jet strength from 1421-2008 for all 20 members of ModE-RA (#41-60)ModE-RA-tilt File with monthly indices of jet tilt from 1421-2008 for all 20 members of ModE-RA (#41-60)ModE-RA-latitude File with monthly indices of jet latitude from 1421-2008 for all 20 members of ModE-RA (#41-60)ModE-Sim-strength File with monthly indices of jet strength from 1421-2008 for all 20 members of ModE-Sim (#41-60)ModE-Sim-tilt File with monthly indices of jet tilt from 1421-2008 for all 20 members of ModE-Sim (#41-60)ModE-Sim-latitude File with monthly indices of jet latitude from 1421-2008 for all 20 members of ModE-Sim (#41-60)ModE-RAclim-strength File with monthly indices of jet strength from 1421-2008 for all 100 members of ModE-RAclim (#01-100)ModE-RAclim-tilt File with monthly indices of jet tilt from 1421-2008 for all 100 members of ModE-RAclim (#01-100)ModE-RAclim-latitude File with monthly indices of jet latitude from 1421-2008 for all 100 members of ModE-RAclim (#01-100)
