Weekly and Monthly Agricultural Rainfall Deficit for Puerto Rico, 2015


Rainfall deficit is defined here as the rainfall minus the reference evapotranspiration (ETo), and has been used in previous studies in Puerto Rico (e.g., Harmsen et al., 2009).  The “true” rainfall deficit is dependent on the potential crop evapotranspiration, however, the reference evapotranspiration may serve as an approximation of the potential crop evapotranspiration for a typical, mature crop.  If the monthly rainfall deficit is positive it means that there was more rainfall than the crop needed, if, however, the rainfall deficit is negative then the monthly rainfall was insufficient to meet the crop water requirement.   To view the monthly estimated rainfall deficit for Puerto Rico, click below:

PRAGWATER now providing daily reference evapotranspiration for Cuba


Daily reference evapotranspiration (ETo) is now available for Cuba at the following link: Northern Caribbean ETo.  The link also includes ETo data for Puerto Rico, the US Virgin Islands, Hispaniola and Jamaica.

Downscaled Climate Data Projections for Puerto Rico Now Available


The Caribbean Landscape Conservation Cooperative (CLCC) has just announced the release of downscaled climate data projections (through 2099) for Puerto Rico.  This is a valuable resource, which will allow scientists from many fields to evaluate climate change impacts in their respective fields.

The data have the following characteristics:

Projections of daily maximum and minimum temperature and twenty-four hour cumulative precipitation for over 200 long-term weather stations throughout the region for the period 1960-2099 based on Global Climate Models (GCMs) from the Third Coupled Model Intercomparison Project (CMIP3) used for the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (AR4 IPCC).

Projection datasets are available for three greenhouse gas emission scenarios: high (A2), medium (A1B), and low (B1). The global model output for precipitation and temperature were downscaled to local station locations by Hayhoe (2013): 71 stations for precipitation, 29 stations for maximum temperatures (Tmax) and 27 stations for minimum temperatures (Tmin).

FINCA ALZAMORA WEATHER DATA AVAILABLE ONLINE


Today a new weather station was installed in the Finca Alzamora, UPRM campus, Mayaguez Puerto Rico.  Data from the weather station are available from two websites:  WeatherLink  or WeatherUnderground.  The WeatherUnderground site allows you to download archived data in a coma delimited text format that can be imported into Excel.  Data being collected include:  air temperature, dew point temperature, RH, wind speed and direction, solar radiation, UV index, soil moisture tension and soil temperature.  A value of the reference evapotranspiration is available on the WeatherLink page.  We are still working out a few kinks, but should have it running smoothly within a few days.

The weather station was purchased with funds from the UPRM NOAA CREST Project.

Photos from a Class Field Trip to the Coloso Valley


On April 25, 2014, students from the TMAG 4035 Soil and Water Management course at  UPRM visited the farm of Sr. Patiño in the Coloso Valley near Aguada, PR.  This post includes some of the pictures that were taken during the field trip.

PR remains on SpaceX’s launch radar


PR remains on SpaceX’s launch radar

Puerto Rico could still land a planned private rocket launchpad that would give a lift to the lagging local economy and make the island a player in a bold new industry that is starting to take off.

SpaceX — formally named Space Exploration Technologies Corp. — has yet to nail down where it will develop the world’s first commercial rocket-launching complex, but a site in Texas has emerged as the frontrunner in a race that includes Puerto Rico, Georgia and Florida.   Read more
