1 | K-factor | 07/23/2013 | PWVSTAC | Dimensionless scale factor between ZWD and PW | CO | NREL | KF | ||||
2 | Precipitable Water (PW) and PW error | 07/23/2013 | PWVSTAC | Precipitable Water amount and the associated error from the estimation process. | CO | NREL | PWV | ||||
3 | D0810016 | Surface pressure | 07/23/2013 | PWVSTAC | Measured using SolarTAC primary Vaisala PTB110 analog pressure sensor by Campbell CR1000 datalogger, then converted to an ASCII string which is sent via UDP to the Trimble Net9R GPS-Based PWV data acquisition system. The pressure measurement is required for the PWV calculations. | CO | NREL | Campbell Scientific | CS106 | SP | |
