Estimated solar radiation from satellite remote sensing is now available for download at https://pragwater.wordpress.com/solar-radiation-data-for-pr-dr-and-haiti/. The half-hourly and daily integrated solar radiation data is provided at a 1-km spatial resolution for PR and a 2-km spatial resolution for DR and Haiti.
Sorry to inform you that the solar radiation data for the Caribbean region, stored on the pragwater.wordpress.com website, has been suspended due to the recent severe weather in Alabama (since April 27th). Data processing should be restored within a few days.
As of May 5th, solar radiation data is now back online. Sorry for the inconvenience.
