Title: Wind resource assessment: San Nicolas Island, California

Abstract

San Nicolas Island (SNI) is the site of the Navy Range Instrumentation Test Site which relies on an isolated diesel-powered grid for its energy needs. The island is located in the Pacific Ocean 85 miles southwest of Los Angeles, California and 65 miles south of the Naval Air Weapons Station (NAWS), Point Mugu, California. SNI is situated on the continental shelf at latitude N33{degree}14` and longitude W119{degree}27`. It is approximately 9 miles long and 3.6 miles wide and encompasses an area of 13,370 acres of land owned by the Navy in fee title. Winds on San Nicolas are prevailingly northwest and are strong most of the year. The average wind speed is 7.2 m/s (14 knots) and seasonal variation is small. The windiest months, March through July, have wind speeds averaging 8.2 m/s (16 knots). The least windy months, August through February, have wind speeds averaging 6.2 m/s (12 knots).

  • During June and July, 1987, Project FIRE was conducted in the Southern California offshore area. Fire (First ISCCP Regional Experimental) is a cloud research program to validate/update the ISCCP (International Satellite Cloud Climatology Project) database and cloud/radiation parameterizations used in the general-circulation models. Coordinated surface, aircraft, and satellite observations of marine stratocumulus cloud within and just above the marine boundary layer were made by a myriad of participants. This report presents data from airborne profiles taken near San Nichols Island, CA, during Operation FIRE (1987). Aerosol size distributions, air and surface temperatures, cloud top temperatures, and relative humidities are tabulated.more » The NOSC airborne platform was employed to investigate the low-level horizontal variability of the marine-boundary-layer structure.« less
  • Shipboard and island measurements show that clean maritime air prevailed over San Nicolas Island, California, for two periods of a day or more each during the twelve days of data collection and moderately continental air prevailed for the remainder of the time. Moderately continental air was encountered out to 200km from shore on 8 and 9 May on a dogleg course from Monterey to the San Nicolas Island area. Maritime air was encountered throughout the direct return trip along the coast, showing that the relative continental/maritime nature of the air at a given location in the area is more dependentmore » upon prevailing winds than on distance from land. Radon measurements at the NRL tower site on San Nicolas Island were in good agreement with shipboard data throughout the area, suggesting a relatively uniform distribution of air over a large area, whether it be maritime or moderately continental. The moderately continental conditions prevailing at San Nicolas Island are not unlike those previously encountered for one or more days in remote Pacific areas in air of Asian origin.« less
  • This report analyzes the local wind resource and evaluates the costs and benefits of supplementing the current diesel-powered energy system on San Nicolas Island, California (SNI), with wind turbines. In Section 2.0 the SNI site, naval operations, and current energy system are described, as are the data collection and analysis procedures. Section 3.0 summarizes the wind resource data and analyses that were presented in NREL/TP 442-20231. Sections 4.0 and 5.0 present the conceptual design and cost analysis of a hybrid wind and diesel energy system on SNI, with conclusions following in Section 6. Appendix A presents summary pages of themore » hybrid system spreadsheet model, and Appendix B contains input and output files for the HYBRID2 program.« less
  • Radon concentration in the near surface air at San Nicolas Island, California, was measured. Unreported results for January and July 1980 are emphasized. For six of eight days during the January session the measured radon concentration was greater than 40 picocuries/cubic m corresponding to a continential air mass. Only the first day involved a maritime air mass with radon concentration less than about 6 picocuries/cubic m. In contrast to all the previous sessions, maritime, air dominated the ten day session in July 1980, with radon concentrations generally less than about 5 picocuries/cubic m.
  • Radon (222) measurements showed that maritime air prevailed for four of the nine days of sampling from April 30 to May 10, 1978. There were, in addition, two days of small continental influence and three days of moderate continental influence. This period was in contrast to May 8 to 22, 1978 (CEWCOM-78) and November 17 to 21, 1979, where in the former, there were only two brief periods of maritime air, and in the latter only one sample was taken that was not continental.
