<br />. <br /> <br />SECTION 3. - PROBE STATIONS <br /> <br />Ten surface meteorological stations were used by CRADP during the 1984-85 <br />field season. All stations were of the PROBE (Portable Remote observations <br />of the Environment) type but wit~ slightly different characteristics. <br />Table 3-1 provides a numerical identification of the stations as well as <br />sensor assignments by channel. <br /> <br />The PROBE stations transmitted data hourly to the GOES-West Satellite which <br />were then retransmitted to a dovml i nk operated by the Bureau of <br />Reclamation in Denver, Colorado. <br /> <br />Stations RRS (Radar/Radiometer Site) and GM3 (Carson Lake) provided wind <br />speed, direction, temperature, humidity with the usual compliment of sen- <br />sors used in prior years. \ The site RRS also used inputs from the adjacent <br />USU Microwave Radiometer. '" - <br /> <br />Stations GMl and GM2 were co-located witl1in the GMO (Grand ~1esd <br />Observatory). The sensor compliment is described in table 3-1. It should <br />be noted that these stations wer'l~ set up with several nonstandC)rd sensors, <br />compared to the past history of this type of station. The wind sensors <br />were rnounted atop a 54 foot tOWE! r adjacent to the observatory and the NAPA <br />250 ft. tower. The wind sensors were made by Hydro-Tech and by MRI. The <br />primary temperature and dewpoint sensor was an aspirated EG&G sensor. A <br />Rosemount Icing Rate Meter was put on the NAPA tower to detect the presence <br />of 1 iquid water. <br /> <br />All data for the field season WE!re integrated for 4 minute - 38 second time <br />blocks every 5 minutes. Table 3..2 gives the site coding, location, and <br />transmit times for each platforlll. <br /> <br />3-1 <br />
