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. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.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. To get a sense of how much these sources agree with each other, you can view a comparison of Bullhead City and the stations that contribute to our estimates of its temperature history and climate. KIFP, 97% 1 mi, 135 ft KEED, 3% 26 mi, 331 ft KBYS, 0% 117 mi, -312 ft © OpenStreetMap contributors Bicycle Lake Army Airfield (KBYS, 0.3%, 117 mi, west, -312 ft elevation change). Needles Airport (KEED, 3.0%, 26 mi, south, 331 ft elevation change).Laughlin/Bullhead International Airport (KIFP, 97%, 0.8 mi, northeast, 135 ft elevation change).The stations contributing to this reconstruction are: The estimated value at Bullhead City is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Bullhead City and a given station. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Bullhead City.įor each station, the records are corrected for the elevation difference between that station and Bullhead City according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. This report illustrates the typical weather in Bullhead City, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016.
