CDAWeb Data Explorer

Plot Data : select one or more variables from list below and press submit.

Also create PS and PDF best quality outputs (all plot types except images and plasmagrams).

Many panels per dataset are allowed but <=4 panels optimal for standard Y-axis height and single page display.

Use coarse noise filtering to remove values outside 3 deviations from mean of all values in the plotted time interval.
Change the X-axis width for time-series and spectrogram PNG plots (NEW default=3).
Plot width factor: Change the Y-axis height for time-series and spectrogram plots (NEW default=2).
multiply by: Autoscale time axis (useful for finding discrete bursts/events).
Combine all time-series and spectrogram plots, for all requested datasets, into one plot file.
Plot overlay options.

Overlay vector components of selected variables.
Overlay selected variables or variable components that are identical among the datasets chosen

(Supported constellations: MMS, Van Allen Probes (RBSP), THEMIS, Cluster, and GOES).

Automatically link all identical variables as variables are selected.

Create V3.9 CDFs for download: select one or more variables from the list below and press submit.

Create Version 2.7.2 compatible CDFs (Default is Version 3.9)
