During ATOMIC/EUREC4A NOAA's P3 aircraft "Miss Piggy" had several sampling objectives, including surveying the large-scale state of the atmosphere with dropsondes (albeit from a lower altitude than HALO), surveying the state of the ocean with remote sensing a AXBTs (oceanic dropsondes), profiling aimed at sampling water isotopes, and in situ sampling of clouds.
Of the high-level sampling strategies used during the campaign the P3 most commonly employed
- transit
- circle
- cloud
- profile
- axbt
The current version (v0.5) of the flight segmentation files is incomplete. The main purpose has been to supply accurate start and end times for the circles in which dropsondes were launched to facilitate the construction of the JOANNE combined dropsonde dataset. Flight segmentation for flight RF01-RF05 was performed by Adriana Bailey at NCAR using flight-level data. Much rougher segmentation of the remaining flights comes from transcription of flight reports by Robert Pincus and should be revised. Feel free to volunteer.
