Daily Photosynthetically Active Radiation (PAR) now available for Puerto Rico


Daily photosynthetically active radiation (PAR) is now available for Puerto Rico. PAR is estimated from net radiation using a regression equation developed in Florida (pre-fire equation, Sumner, 2001). Click here to access images and data

Students from across Puerto Rico attended the NOAA CREST Summer Camp this week on the UPRM Campus.  This afternoon, they attended a workshop by Dr. Eric Harmsen, which focused on the use of GOES-PRWEB for scheduling irrigation in Puerto Rico.  Irrigation scheduling is important for water conservation and for achieving optimal crop yields.  The presentation is provided below:

GOES-PRWEB results questionable until NEXRAD is back online

I received an email from Ernesto Rodriguez of the National Weather Service in San Juan this morning, regarding the rainfall data from NOAA’s Advanced Hydrologic Prediction Service (AHPS).  GOES-PRWEB uses the AHPS, so until NEXRAD is back online, the GOES-PRWEB results will be questionable.


Here is the email from Ernesto:

AHPS data is questionable without the NEXRAD. Until the NEXRAD returns, the AHPS analysis will be created using the Terminal Doppler Radar(TWDR) at Punta Salinas(Toa Baja) and rain gauges(from USGS).
Please, remember that the TDWR is not very useful to detect showers over the southern half of Puerto Rico and the extreme west of Puerto Rico.
