![]() ![]() 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. 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. KNYC, 90% 0 mi, 39 ft KLGA, 6% 5 mi, -105 ft KTEB, 4% 7 mi, -108 ft © OpenStreetMap contributors 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. ![]() The Department is fully stocked with over 700 million pounds of salt.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. The Department has more than 2,000 plowable vehicles. Additionally, the Department's collection trucks will be turned into snow plows, ready to plow once two inches of snow has fallen. Crews have been placing pretreatment on roadways. The New York City Department of Sanitation says the full fleet of over 700 salt spreaders will be positioned and ready to operate starting Monday afternoon. Open Restaurants roadway dining may operate as normal during this snow event if the business owner deems it is safe to do so. NEW YORK CITY PREPSĪlternate Side Parking regulations will be suspended on Tuesday, February 28. Bus service will be adjusted based on road conditions around the city, and service curtailments on a route-by-route basis are possible.Ĭheck the MTA website for updates. New York City articulated buses will be fitted with chains for Tuesday morning rush hour. MTA says employees will be deployed throughout the operating region spreading salt and clearing surfaces of snow, keeping signals, switches, and third rails operating, and attending to any weather-related challenges. The prep work ahead of the first significant snow storm of the year actually started days ago. ![]() Many of the roads in town already have a coat of brine. ![]()
