Description
Quality controlled and gap-filled continuous solar irradiance measurements at 16 m above ground level measured on a boom extending from the tower above the forest canopy at Hartheim Forest Research Site (ICOS Associate Ecosystem Site DE-Har, UFR Code: HARTHM, 7.59814ºE, 47.93391ºN, 201 m) measured using a ventilated pyranometer CM21 (Kipp & Zonen, Delft, Netherlands). The pyranometer was operated on the 30 m tower connected to a C23X data logger.
- Quality controlled above-canopy solar irradiance data are available and aggregated at 10min, 30min, hourly, daily, monthly and yearly resolution for the year 2013. Values are averages during the periods shown.
- Solar irradiance in this dataset is equal "global irradiance" or "global hemispherical irrandiance" and does not distinguish between direct and diffuse irradiance.
- Modeled extraterrestrial irradiance (based on the NOAA General Solar Position Calculations of the NOAA Global Monitoring Division and considering the Earth's elliptical orbit) is provided for comparison, along with the ratio of solar irradiance to extraterrestrial irradiance at 10min, 30min, hourly, daily, monthly and yearly resolution. Extraterrestrial irradiance is average of period show.
- Number of hours with solar irradiance >5 W/m2 (daylight hours) and > 120 W/m2 (sometimes used as threshold for "sun hours") provided on daily, monthly, and annual scale.
- Number of days with solar irradiance >5 W/m2 (quality check) and > 120 W/m2 ("sun hours") provided on monthly, and annual scale.
- Detailed information on gap-filled data is provided.
- Note: All times are provided in UTC, not local time.
