Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.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. The station records are corrected for the elevation difference between the station and Mardan according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. There is only a single weather station, Benazir Bhutto International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Mardan.Īt a distance of 117 kilometers from Mardan, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records. This report illustrates the typical weather in Mardan, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016.
