ORION® Setup Sample Clauses

ORION® Setup. The ORION® open path analyser was deployed at OR’s Hellisheiði geothermal power complex, near to active production well sites. The site chosen was the ‘Hot Spring Hill’ area (UTM 27W 483195 7098022). This site is of interest to OR as there is much geothermal activity at the surface, including gas escaping from fumaroles. An overview of the site layout is shown in Figure 1a and 1b. Figure 1a shows the general settings and the location of the area under test with respect to the main control building. Figure 1b focuses on the area specifically under consideration and shows the configuration of the instrument and retroreflector deployment on the site. Eight retroreflectors were deployed in a 180° arc over a 150 x 350m area to the south-east of the instrument. Their positional co-ordinates are given below in Table 1. A sonic anemometer was deployed together with temperature, pressure and humidity sensors to measure the wind vector and associated atmospheric data needed for the final data processing. Table 1. Listing of all the retroreflector geographical co-ordinates corresponding to positions marked in Figure 1. Figure 2a. Picture of one of retroreflectors deployed against a backdrop of the site with active fumaroles.
