Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents.
Shortwave radiation includes visible light and ultraviolet radiation. The average daily incident shortwave solar energy in Niagara Falls is increasing during April, rising by 1. For the purposes of this report, the geographical coordinates of Niagara Falls are The topography within 2 miles of Niagara Falls contains only modest variations in elevation, with a maximum elevation change of feet and an average elevation above sea level of feet. Within 10 miles also contains only modest variations in elevation feet.
Within 50 miles contains only modest variations in elevation 1, feet. This report illustrates the typical weather in Niagara Falls, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Niagara Falls.
For each station, the records are corrected for the elevation difference between that station and Niagara Falls according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. The estimated value at Niagara Falls is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Niagara Falls and a given station.
To get a sense of how much these sources agree with each other, you can view a comparison of Niagara Falls and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.
All data relating to the Sun's position e. 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 kilometer grid. Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database. Time zones for airports and weather stations are provided by AskGeo.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. 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.
