Sign Up For AlertsĪll new students and new employees should register for emergency alerts. You will be notified via text message and email. Please review our full terms contained on our Terms of Service page.Manhattan College’s e2campus emergency notification system is used to communicate with members of the campus community regarding situations that may pose a threat to the safety, health or well-being of members of our community and/or weather situations that may interrupt scheduled classes or activities. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series.

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 Manhattan and the stations that contribute to our estimates of its temperature history and climate. Teterboro Airport (KTEB, 3.6%, 7 mi, northwest, -108 ft elevation change).
La Guardia Airport (KLGA, 6%, 5 mi, east, -105 ft elevation change).New York City, Central Park (KNYC, 90%, 0.3 mi, southwest, 39 ft elevation change).The stations contributing to this reconstruction are: The estimated value at Manhattan is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Manhattan and a given station. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Manhattan.įor each station, the records are corrected for the elevation difference between that station and Manhattan 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 Manhattan, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016.
