We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
Muggy conditions are essentially unheard-of in Rūdbār on May 28.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in Rūdbār on May 28 varies throughout the day, with a daily average of 10.5 miles per hour.
The windiest time of day is around 4:00 PM, with an average hourly wind speed of 14.1 miles per hour, mostly staying between 9.6 miles per hour and 18.0 miles per hour, and rarely falling below 6.4 miles per hour or exceeding 22.5 miles per hour.
The calmest time of day is around 4:30 AM, with an average hourly wind speed of 7.2 miles per hour, mostly staying between 5.2 miles per hour and 9.0 miles per hour, and rarely falling below 3.3 miles per hour or exceeding 11.5 miles per hour.
For reference, on June 15, the windiest day of the year, the daily average wind speed is 11.1 miles per hour, while on December 9, the calmest day of the year, the daily average wind speed is 6.5 miles per hour.

Shortwave Solar Power
This section discusses the incident shortwave solar power 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 peak incident shortwave solar power per square meter is 1.03 kilowatts at around 11:45 AM.
In contrast, the corresponding value on June 18, the brightest day of the year, is 1.04 kilowatts at around 10:45 AM. The corresponding value on December 20, the darkest day of the year, is 0.61 kilowatts at around 10:45 AM.

Temperature and Dew Point
There is only a single weather station, Zabol, in our network suitable to be used as a proxy for the historical temperature and dew point records of Rūdbār.
At a distance of 146 kilometers from Rūdbār, 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.
The station records are corrected for the elevation difference between the station and Rūdbār according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
All 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.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . 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.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
