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 Cleveland is decreasing during September, falling by 1. For the purposes of this report, the geographical coordinates of Cleveland are The topography within 2 miles of Cleveland 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 contains only modest variations in elevation feet. Within 50 miles also contains significant variations in elevation feet. This report illustrates the typical weather in Cleveland, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Cleveland. For each station, the records are corrected for the elevation difference between that station and Cleveland 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 Cleveland is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Cleveland and a given station. To get a sense of how much these sources agree with each other, you can view a comparison of Cleveland 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.

We assume no responsibility for any decisions made on the basis of the content presented on this site. 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.
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.
