1,PWVSTAC,30-Minute GPS-based Precipitable Water Vapor measurements <ul> 	<li>Raw data is sampled by <a href="http://www.trimble.com/infrastructure/netr9-gnss-reference-receiver.aspx">Trimble Net9R</a> data acquisition every 30 or 60 seconds and send to <a href="http://www.suominet.ucar.edu/">UCAR</a> every hour for data processing. 	<li>PWV processed data is grabbed by MIDC every hour (25 minutes from the top of the hour) from the <a href="http://www.suominet.ucar.edu/cgi-bin/pw_plots.cgi?site=STA2">UCAR web site</a> and converted to "classic" Campbell data logger format so that it can be made available on the MIDC web site; which requires converting UTC to Mountain Standard Time (MST).  Note:  Prior to January 2017 the SolarTAC PWV data on the UCAR web site was using a different <a href="http://www.suominet.ucar.edu/cgi-bin/pw_plots.cgi?site=STAC">station identifier</a>. 	<li>Data processing at UCAR takes 1 hour 35 minutes and resulting data sample rate is 30 minutes. </ul>
