| 1 | Air Temperature, Relative Humidity, and Surface pressure | 08/22/2013 | PWVUO | Measured using Vaisala PTU300 pressure/humidity/temperature transmitter, the ASCII string output is sent via RS-232 to the Trimble Net9R as requested (every 60 seconds). The pressure measurement is required for the PWV calculations. | OR | NREL | MET | ||||
| 2 | K-factor | 08/22/2013 | PWVUO | Dimensionless scale factor between ZWD and PW | OR | NREL | KF | ||||
| 3 | Precipitable Water (PW) and PW error | 08/22/2013 | PWVUO | Precipitable Water amount and the associated error from the estimation process. | OR | NREL | PW | ||||
| 4 | Zenith Hydrostatic Delay (ZHD) | 08/22/2013 | PWVUO | Computed from surface pressure measurements. | OR | NREL | ZHD | ||||
| 5 | Zenith Total Delay (ZTD) | 08/22/2013 | PWVUO | Sum of ZWD and ZHD | OR | NREL | ZTD | ||||
| 6 | Zenith Wet Delay (ZWD) | 08/22/2013 | PWVUO | Estimated in GPS analysis software. Directly scalable to PW. | OR | NREL | ZWD |
