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. Figure 1a. General settings of the area under test (yellow perimeter) with respect to the main power plant control building. Figure 1b. Overview of the geothermal well field site, which supplies the Hellisheiði power plant. The ORION® was located at the corner of the pad containing two geothermal xxxxx and surveyed over a 180° arc from south-west to north-east of the pad. 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.
