GOES-PRWEB results questionable until NEXRAD is back online

/ pragwater / 2 Comments

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.
Regards,
–Ernesto Rodriguez

Replacement Weather Satellite for GOES East

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.  For more information visit http://www.accuweather.com/en/weather-news/key-us-weather-satellite-goes/78844

This post has implications on data from the following pragwater web pages:

Groundwater over-exploited in agricultural regions, study finds


Groundwater footprints of aquifers that are important to agriculture are significantly larger than their geographic areas. Higher footprint values indicate widespread stress. (Nature Publishing Group)
