where R is the release number (starts from one) with leading zeros. The first row in the trajectory file contains metadata as a set of key value pairs, while the the second row contains the header. The table below gives a detailed description about the different columns.
| Column | Name (header) | Different name in installed version (5a) | Units | Description |
|---|---|---|---|---|
| 1 | time | s | the elapsed time in seconds since the middle point of the release interval | |
| 2 | meanLon | degrees | mean longitude position for all the particles | |
| 3 | meanLat | degrees | mean latitude position for all the particles | |
| 4 | meanZ | m | mean height for all the particles (above sea level) | |
| 5 | meanTopo | m | mean topography underlying all the particles | |
| 6 | meanPBL | meanABL | m | mean PBL (Planetary Boundary Layer) height for all the particles (above ground level) |
| 7 | meanTropo | m | mean tropopause height at the positions of particles (above sea level) | |
| 9 | meanPv | PVU | mean potential vorticity for all the particles | |
| 10 | rmsHBefore | km | total horizontal RMS (root mean square) distance before clustering | |
| 11 | rmsHAfter | km | total horizontal RMS distance after clustering | |
| 12 | rmsVBefore | m | total vertical RMS distance before clustering | |
| 13 | rmsVAfter | m | total vertical RMS distance after clustering | |
| 14 | pblFract | ablFract | % | fraction of particles in the PBL |
| 15 | pv2Fract | startoFract | % | fraction of particles with PV<2pvu |
| 16 | tropoFract | % | fraction of particles within the troposphere | |
| 17* | clLon_N | degrees | mean longitude position for all the particles in cluster N | |
| 18* | clLat_N | degrees | mean latitude position for all the particles in cluster N | |
| 19* | clZ_N | m | mean height for all the particles in cluster N (above sea level) | |
| 20* | clFract_N | % | fraction of particles in cluster N (above sea level) | |
| 21* | clRms_N | km | total horizontal RMS distance in cluster N |
Columns 17-21 get repeated for each cluster.
Receptor output
Output at receptor points are produced when Receptors is set to on in FLEXPART Run. The binary file generated by FLEXPART is split according to species and converted to CSV.
