Figure 22.46: Troposphere estimates in TRP file format.<br />

The positive model numbers (1 up to 15) correspond to the same models but<br />

with observed meteorological values used for the computation of the a priori<br />

troposphere zenith delay.<br />

• Mapping function:<br />

1/cos(z) = 1,<br />

Hopfield = 2,<br />

Dry Niell = 3,<br />

Wet Niell = 4,<br />

• Gradient model:<br />

No estimation = 0,<br />

Tilting = 1,<br />

Linear = 2.<br />

• Minimum elevation in degrees<br />

• Tabular interval for zenith parameters and for gradient parameters in seconds<br />

(3) Data part:<br />

• Station name.<br />

• Station flag (see Section 22.8.5).<br />

• Epoch for piece-wise linear parameter representation (second epoch is blank).<br />

In <strong>Version</strong> 4.2 start epoch and end epoch were used for piece-wise constant<br />

representation.<br />

• Zenith delay (total effect) from the a priori model (zero, if observed meteo used)<br />

in m.<br />

• Estimated value (correction to the a priori zenith value) in m.<br />

• Estimated formal rms of the correction in m.<br />

• Total zenith delay (sum of a priori value and estimated correction) in m.<br />

• Gradient parameters and formal rms in north and east directions in m (not<br />

displayed in Figure 22.46).<br />

If a troposphere is introduced only the estimated values (CORR U, CORR N, CORR E) are used.<br />

The a priori zenith delay is reconstructed using the model specified in the header line.<br />
