HelioClim-3 unified format

Last update: Feb. 2018

 

Horizontal plane (tilt =0)

  1. Date: format "yyyy-mm-dd"
  2. Time: format "HH:MM"
  3. Global Horizontal irradiation over the period in Wh/m² (-999 if no data)
  4. Clear-Sky: Irradiation over the period if the sky were clear in Wh/m²
  5. Top of Atmosphere: Irradiation over the period at the top of the atmosphere (extraterrestrial) in Wh/m²
  6. The reliability column has several forms depending of the time step:
    1. Code: 0: no data, 1: sun below horizon, 2: satellite assessment, 5: interpolation in time, 6: forecast
    2. Nb slots (%): ratio of the number of valid slots and the number of slots during the daylength in percent
    3. Nb valid days: number of valid days in the period

  If option "+Add Meteo" is set:

  1. Temperature: Temperature at 2 m above ground in Kelvins
  2. Relative Humidity: Relative humidity at 2 m above ground in %
  3. Pressure: Pressure at ground level in hPa
  4. Wind speed: Wind speed at 10 m above ground in m/s
  5. Wind direction: Wind direction at 10 m above ground (0 means from North, 90 from East...) in degrees
  6. Rainfall: Rainfall in kg/m2 (= rain depth in mm)
  7. Snowfall: in kg/m2
  8. Snow depth: in m

Tilt different from 0 (fix-tilted or trackers)

  1. Date: format "yyyy-mm-dd"
  2. Time: format "HH:MM"
  3. Direct Inclined: irradiation over the period in Wh/m² (-999 if no data)
  4. Diffuse Inclined irradiation over the period in Wh/m² (-999 if no data)
  5. Reflected inclined irradiation over the period in Wh/m² (-999 if no data)
  6. Global Inclined irradiation over the period in Wh/m² (-999 if no data)
  7. Direct Horizontal irradiation over the period in Wh/m² (-999 if no data)
  8. Diffuse Horizontal irradiation over the period in Wh/m² (-999 if no data)
  9. Global Horizontal irradiation over the period in Wh/m² (-999 if no data)
  10. Clear-Sky: Irradiation over the period if the sky were clear in Wh/m²
  11. Top of Atmosphere: Irradiation over the period at the top of the atmosphere (extraterrestrial) in Wh/m²
  12. The reliability column has several forms depending of the time step:
    1. Code: 0: no data, 1: sun below horizon, 2: satellite assessment, 5: interpolation in time, 6: forecast
    2. Nb slots (%): ratio of the number of valid slots and the number of slots during the daylength in percent
    3. Nb valid days: number of valid days in the period
