Both the hourly and daily data are provided in the product. The hourly data are grouped by day in distinct NetCDF files, which are named as “EPIC_SW_PAR_Hourly_yyyymmdd.nc” where “yyyy”, “mm”, and “dd” denote year, month, and day (UTC time). The daily data are grouped by month in distinct NetCDF files, which are named as “EPIC_SW_PAR_Daily_yyyymm.nc” where “yyyy”, and “mm” denote year and month (UTC time). Each NetCDF file contains latitude, longitude, time, diffuse SW, direct SW, diffuse PAR, direct PAR, and the corresponding quality flags which indicates where the pixel is gap-filled or not.
The scale factor for the direct and diffuse SW/PAR is 0.1. The total SW/PAR can be calculated by combining the direct and diffuse components. The information about the version, creation date, reference, contact mails, and other comments are also included in the file.
