Daily Reference Evapotranspiration (ETo) for Haiti and the Dominican Republic
Daily reference evapotranspiration (ETo) is now available for Haiti and the Dominican Republic. CLICK HERE to visit the new pragwater page, which provides a link to the daily image data and the method background information. The page also provides information related to the practical application of the results for scheduling irrigation in Haiti and the Dominican Republic.
ACKNOWLEDGEMENTS: This research received partial funding from the following sources: NOAA-CREST (grant NA06OAR4810162) and USDA Hatch Project (Hatch-402). Special thanks to Dr. John Mecikalski for providing the solar radiation data, and Alejandra Rojas for providing various GIS maps used in this research. I would like to thank my student, Victor Reventos, who made this possible through his Python programming skills.

The GOES-13 satellite was offline from September 25 through October 19, 2012. During this time, solar radiation data for PR and the northern Caribbean Region were not available. However, the water and energy balance algorithm (GOES-PRWEB) continued to function with estimated solar radiation data. GOES-PRWEB results for solar radiation and 24 other hydro-climate variables are available at

This is bad news for the Caribbean Region. And this is very bad news for those of you that regularly download solar radiation data from pragwater.com or rely on results from GOES-PRWEB. The National Oceanic and Atmospheric Administration (NOAA) confirmed Monday that GOES-13 has been placed in stand-by mode, following increased vibrations, or “noise,” observed in imagery over the past couple of days.
