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.
I will be offering the following two courses next semester at UPR-Mayaguez. Please click links for more information.
This week we announced that GOES-PRWEB is operational. Daily data since January 1, 2010 is now available at the link:
http://academic.uprm.edu/hdc/GOES-PRWEB_RESULTS/
Today, 26 months of monthly averages and totals were uploaded to the link: http://academic.uprm.edu/hdc/GOES-PRWEB_MONTHLY_RESULTS/
Annual averages and totals will be uploaded next week.

Incidently, I noticed an interesting result in yesterdays data. In the area of the Arecibo Space Observatory, there was approximately 300 mm of rainfall and almost as much surface runoff. This was a really huge storm, 300 mm is around 12 inches!! Over 12 inches of rain was measured at the USGS Station 50028000 RIO TANAMA NR UTUADO. The precipitation, discharge and gauge height plots from the USGS website are given below.
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:

New results will be published daily. Historical results are available from January 1, 2010. A list of the available output is provided below.

Management of Drip/Trickle or Micro Irrigation
By Megh R. Goyal, PhD, Professor in Agricultural and Biomedical Engineering, University of Puerto Rico
http://www.appleacademicpress.com
This important book—the only complete, one-stop manual on microirrigation worldwide—offers knowledge and techniques necessary to develop and manage a drip/trickle or micro irrigation system. The simplicity of the contents facilitates a technician to develop an effective micro irrigation system. Management of Drip/Trickle or Micro Irrigation includes the basic considerations relating to soil-water-plant interactions, with topics such as methods for soil moisture measurement; evapotranspiration; irrigation systems; tensiometer use and installation; principles of drip/ micro/trickle irrigation; filtration systems; automation; chloration; service and maintenance; design of drip irrigation and lateral lines; the evaluation of uniformity of application; and an economical analysis for selecting irrigation technology.
