Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database. Land Use data comes from the Global Land Cover SHARE database, published by the Food and Agriculture Organization of the United Nations.Įlevation data comes from the Shuttle Radar Topography Mission (SRTM), published by NASA's Jet Propulsion Laboratory. This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid. The stations on which we may fall back include but are not limited to Reno/Tahoe International Airport, Lake Tahoe Airport, Truckee Tahoe Airport, Bridgeport Sonora Junction, Blue Canyon-Nyack Airport, Naval Air Station Fallon, Placerville Airport, and Derby Field.Īll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition, by Jean Meeus.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis.
For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations. In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required. When available, historical temperature and dew point measurements are taken directly from this weather station. This report illustrates the typical weather at Carson Airport, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016.Ĭarson Airport has a weather station that reported reliably enough during the analysis period that we have included it in our network.
