Model Comparisons
Below are model versus balloon track comparisons. Click on model ID for details regarding temporal resolution and compilation.

"No Nudge" data are compiled by resetting the actual balloon altitude at each new model initialization.

"Nudged" data are compiled by forcing the actual balloon altitude at each model time step.

Numbers 1, 2, 3 & 4 below correlate to Balloons 1, 2, 3, & 4 respectively.
