It includes time series of the Montgomery streamfunction contour level from May to September for each day at 12:00 UTC during the period 1980-2023 at 350 K, 370 K, 390 K and 410 K, representing the boundary of the Asian Summer Monsoon Anticyclone as calculated by the proposed method. In addition, we provide the Montgomery streamfunction data defined on a regular 1° × 1° grid.CC0 WaiverKachula O., Vogel B., Günther G., and Müller R.: An optimization-based approach to track the Asian summer monsoon anticyclone across daily and interannual variabilitymsfb_05_09_350K.ncapplication/x-netcdfmsfb_05_09_370K.ncapplication/x-netcdfmsfb_05_09_390K.ncapplication/x-netcdfmsfb_05_09_410K.ncapplication/x-netcdfts_background_350K.ncapplication/x-netcdfts_background_370K.ncapplication/x-netcdfts_background_390K.ncapplication/x-netcdfts_background_410K.ncapplication/x-netcdf
