irrad_Kipp.data: Ground level solar irradiance (measured)

Description

Dataset containing mean, maximum, minimum and standard deviation values for global radiation data expressed as (energy) irradiance. Values are summaries of 12 consecutive readings acquired once every 5 s. The data set covers 17 consecutive days.

Usage

irrad_Kipp.data

Format

A data frame with 24479 rows and 5 variables. variables.

Details

The variables are as follows:

• time_EEST POSIXct Local time according to EET coordinates.

• UTC POSIXct Local time according to UTC.

• e_irrad_mean numeric (W m-2)

• e_irrad_min numeric (W m-2)

• e_irrad_max numeric (W m-2)

• e_irrad_sd numeric (W m-2)

These data are part of a much larger data set (Aphalo, 2023). Instrument used: Kipp SMP3 smart pyranometer, factory calibrated, mounted on permanent tripod at approximately 2 m height. Data collected with a Campbell Scientific CR6 datalogger. Wavelength sensitivity range of the pyranometer is 300 nm to 2800 nm. Location: Viikki campus of the University of Helsinki. Coordinates: 60.226803 N, 25.019205 E.
