Satellite-Based Daily Evapotranpiration Estimation in Puerto Rico
Presented by Eric Harmsen

Part 1 Part 2 Part 3 Part 4 Part 5

Since this presentation was given in June of 2009, we have completed the operational version of the GOES-Puerto Rico Water and Energy Balance algorithm (GOES-PRWEB). For more information click HERE.

Monthly Average Solar Radiation Images Available for Puerto Rico


Monthly average solar radiation images for Puerto Rico can be downloaded at the following link:
http://academic.uprm.edu/hdc/GOES-PRWEB_MONTHLY_RESULTS/solar_radiation/

The images includes 26 months of data starting in January 2010.  Other atmospheric/hydrologic data images are also available at the following link:

GOES-PUERTO RICO WATER AND ENERGY BALANCE (GOES-PRWEB) IS NOW OPERATIONAL


GOES-PRWEB is finally operational.  I would like to thank my student, Victor Reventos, who made it possible through his Python programming skills.  Here is a link to the results:

CROP WATER USE ( HARGREAVES ET EQUATION) WOLFRAM ALPHA WIDGET


CROP WATER USE ( HARGREAVES ET EQUATION) NEW WOLFRAM ALPHA WIDGET. Reference: Hargreaves, G. H. and Z. A. Samani, Reference Crop Evapotranspiration from Temperature. Appl. Eng. Agric., ASAE. 1(2). 1985,. pp.96-99.

Widget Application: Suppose you want to schedule irrigation by replacing the water evapotranspired by your crop each day.  1. Click on the appropriate link to get yesterdays solar radiation for your location: Puerto Rico or Northern Caribbean, 2. Check the internet for the average daily air temperature at your location (average = (minimum + maximum)/2),  3. Get the appropriate crop coefficient for your crop from this link, and 4. Finally, enter solar radiation, air temperature and crop coefficient into the widget to estimate ET. Multiply ET x acres x 1069.0663 to get the number of gallons of water you need to apply to your field.
