TPEx 2024 observational data and model data along flight path - Merged

Content TPEx (TropoPause compositon gradients and mixing Experiment) was the central field campaign of the TPChange research center. It took place in early summer 2024 with measurement flights in the time window from 10 to 21 June 2024. All data have a time resolution of 1 second. The data basis was the time from the GPS files. Existing data gaps in the time series were filled with NaNs. For multiple data points per second, an average was used. If there was no data from a measuring device during a flight, or not all variables were available, they were added with NaNs.
