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 | meanPBLmeanABL | 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) | |
| 8 | meanPv | PVU | mean potential vorticity for all the particles | |
| 9 | rmsHBefore | km | total horizontal RMS (root mean square) distance before clustering | |
| 10 | rmsHAfter | km | total horizontal RMS distance after clustering | |
| 11 | rmsVBefore | m | total vertical RMS distance before clustering | |
| 12 | rmsVAfter | m | total vertical RMS distance after clustering | |
| 13 | pblFract | ablFract | % | fraction of particles in the PBL |
| 14 | pv2FractstartoFract | % | fraction of particles with PV<2pvu | |
| 15 | tropoFract | % | fraction of particles within the troposphere | |
| 16* | clLon_N | degrees | mean longitude position for all the particles in cluster N | |
| 17* | clLat_N | degrees | mean latitude position for all the particles in cluster N | |
| 18* | clZ_N | m | mean height for all the particles in cluster N (above sea level) | |
| 19* | clFract_N | % | fraction of particles in cluster N (above sea level) | |
| 20* | clRms_N | km | total horizontal RMS distance in cluster N |
