RE_Atlas Solar Photovoltaic (irena:us_solar_all_120512)
This data provides monthly average and annual average daily total solar resource averaged over surface cells of 0.1 degrees in both latitude and longitude, or about 10 km in size. The insolation values represent the resource available to fixed flat plate system tilted towards the equator at an angle equal to the latitude. The data are created using the SUNY Satellite Solar Radiation model (Perez, et.al., 2002). The data are averaged from hourly model output over 8 years (1998-2009). This model uses hourly radiance images from geostationary weather satellites, daily snow cover data, and monthly averages of atmospheric water vapor, trace gases, and the amount of aerosols in the atmosphere to calculate the hourly total insolation (sun and sky) falling on a horizontal surface. The direct beam radiation is then calculated using the atmospheric water vapor, trace gases, and aerosols, which are derived from a variety of sources. Where possible, existing ground measurement stations are used to validate the data. Source: Perez-SUNY/NREL, 2007 The data for Alaska was created using the Climatological Solar Radiation Model (Maxwell, George and Wilcox, 1998; George and Maxwell, 1999). This model uses information on cloud cover, atmospheric water vapor and trace gases, and the amount of aerosols in the atmosphere, to calculate the monthly average daily total insolation (sun and sky) falling on a horizontal surface. The cloud cover data used as input to the CSR model are an 8-year histogram (1985 - 1992) of monthly average cloud fraction provided for grid cells of approximately 40km x 40km in size. Thus, the spatial resolution of the CSR model output is defined by this database. The data were obtained from the National Climatic Data Center in Asheville, North Carolina, and were developed from the U.S. Air Force Real Time Nephanalysis (RTNEPH) program. Atmospheric water vapor, trace gases, and aerosols are derived from a variety of sources, as summarized in the references. The procedures for converting the modeled global horizontal insolation into the insolation received by a flat plate collector at latitude tilt are described in Marion and Wilcox (1994).
Deep Enhanced Geothermal Systems Polygons United States SMU/NREL 2009 (irena:reatlas_us_geothermal)
Map does not include shallow Deep Enhanced Geothermal Systems (EGS) resources located near hydrothermal sites or USGS assessment of undiscovered hydrothermal resources. Source data for deep EGS includes temperature at depth from 3 to 10 km provided by Southern Methodist University Geothermal Laboratory (Blackwell & Richards, 2009) and analyses (for regions with temperatures ≥150°C) performed by NREL (2009). N/A regions have temperatures less than 150°C at 10 km depth and were not assessed for deep EGS potential. Temperature at depth data for deep EGS in Alaska and Hawaii not available. Qualitative classes are based on temperature and depth ranges. Temperature values are not exclusive to any single class and may be located at different depths from one class to the next. Classes express approximate favorability for geothermal resource, with a lower number indicating the possibility of a higher potential value.
Identified Hydrothermal Sites Points United States USGS 2008 (irena:reatlas_geothermalpoint)
Identified hydrothermal sites from Assessment of Moderate- and High-Temperature Geothermal Resources of the United States (2008). This document summarizes the result of the resource assessment in which the identified sites in the data set were gathered and analyzed. The methodology used to develop resource estimates for the identified hydrothermal sites is available in A Review of Methods Applied by the U.S. Geological Survey in the Assessment of Identified Geothermal Resources. Site attributes list most likely values for temperature and reservoir volume and mean estimate for resource potential, taken from a distribution of values.
