![]() 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 Bar Harbor and the stations that contribute to our estimates of its temperature history and climate. KBHB, 93% 9 mi, 33 ft CWSS, 4% 74 mi, 33 ft CWVU, 3% 92 mi, 0 ft © OpenStreetMap contributors (CWVU, 2.9%, 92 mi, east, 0 ft elevation change) (CWSS, 4.0%, 74 mi, northeast, 33 ft elevation change) Hancock County-Bar Harbor Airport (KBHB, 93%, 9 mi, northwest, 33 ft elevation change).The stations contributing to this reconstruction are: The estimated value at Bar Harbor is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Bar Harbor and a given station. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Bar Harbor.įor each station, the records are corrected for the elevation difference between that station and Bar Harbor according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. Beware! The strength of the UV rays is increased nearly double-fold by the reflection of the snow.This report illustrates the typical weather in Bar Harbor, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. The solar radiation is most powerful near the mid-day, so the exposure to the direct Sun should be reduced accordingly. ![]() Take precautions - Protection against sun damage is advised. Note: In October, the average maximum UV index of 3 translate into the following recommendations: A UV Index estimate of 3 to 5 represents a medium vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
