## Trajectory / Display / Endpoint File Format

The trajectory model generates its own text output file of ASCII end-point positions. The trajectory display program processes the end-point file. The format of the file is given below:

Record #1

I6 - Number of meteorological grids used in calculation

Records Loop #2 through the number of grids

A8 - Meteorological Model identification
5I6 - Data file starting Year, Month, Day, Hour, Forecast Hour

Record #3

I6 - number of different trajectories in file
1X,A8 - direction of trajectory calculation (FORWARD, BACKWARD)
1X,A8 - vertical motion calculation method (OMEGA, THETA, ...)

Record Loop #4 through the number of different trajectories in file

4I6 - starting year, month, day, hour
2F9.3 - starting latitude, longitude
F8.1 - starting level above ground (meters)

Record #5

I6 - number (n) of diagnostic output variables
n(1X,A8) - label identification of each variable (PRESSURE, THETA, ...)

Record Loop #6 through the number of hours in the simulation

I6 - trajectory number
I6 - meteorological grid number or antecedent trajectory number
5I6 - year month day hour minute of the point
I6 - forecast hour at point
F8.1 - age of the trajectory in hours
2F9.3 - position latitude and longitude
1X,F8.1 - position height in meters above ground
n(1X,F8.1) - n diagnostic output variables (1st to be output is always pressure)
