Global Horizontal Irradiance Dataset for Mauritius, Rodrigues, and Agalega Islands.

This dataset comprises Global Horizontal Irradiance (GHI) data collected at one-minute intervals from 12 sites across Mauritius, Rodrigues, and Agalega islands. The sites include Agalega, Bramsthan, Curepipe, Ferney, Goodlands, Grenade, La Mivoie, Mahebourg, Nicolay, Port Mathurin, Rose Hill, and Souillac. The data were acquired using base stations consisting of TMF100 Data Loggers and MS-802 EKO Pyranometers. Each site's data collection duration varies. The dataset is stored in CSV format and includes timestamp in the format yyyy-mm-dd HH:MM, site name, latitude, longitude, and Global Horizontal Irradiance measurements (W/m²). The Global Horizontal Irradiance data for each site was organized into individual .csv files contained in the folder named by Site, with each Site stored within its respective island directory. These island directories, in turn, were stored within the main Data directory. An example of file name format for the csv files is “MAURITIUS_Bramsthan_lat_-20.214_lon_57.737_2018-01-01_2018-01-31”, “Mauritius” corresponds to island, “Bramsthan” to the Site Name, “-20.214” to the latitude, “57.737” to the longitude, “2018-01-01” to the first date of recorded data for the csv and “2018-01-31” to the last date of recorded data for the csv.
